High-Impact Chemicals and Their Role in Gold Recovery

By ATO ASEFOAH DADZIE

Gold recovery is one of those subjects that can seem deceptively simple from the outside. You dig up rock, you crush it, you apply a few steps, and out comes the gold—right? In reality, though, it’s a carefully engineered process that hinges on precision chemistry. The difference between a 70% recovery rate and a 92% one can come down to the chemicals used—and how they’re applied.

At JOBEX COMPANY LTD in Ghana, we’ve been fortunate to work with clients and partners across the gold mining sector who’ve trusted us to supply, store, and sometimes help coordinate the usage of high-impact chemicals. It’s not something we take lightly. The chemicals used in gold extraction aren’t just potent—they’re sensitive, tightly regulated, and operationally critical.

Let’s talk about what we’ve learned.

The first, and most widely known, is cyanide. Specifically, sodium cyanide. For decades, it’s been the cornerstone of gold leaching operations. But the way it’s handled—everything from concentration levels to contact time—makes all the difference. Too little, and you waste ore. Too much, and you risk unnecessary environmental exposure and higher detoxification costs. We’ve supported projects that adjusted cyanide dosing by as little as 0.02% and saw measurable yield improvements.

But the conversation doesn’t stop at cyanide. Increasingly, alternative leaching agents like thiosulfate or glycine-based solutions are entering the market. They’re less toxic, and while adoption is still emerging in parts of West Africa, we’re seeing more exploration firms experimenting with them—especially in environmentally sensitive zones. We’ve helped import pilot batches of these alternatives for clients running test cells, and the early feedback is promising, albeit still evolving.

Another crucial chemical? Flocculants and coagulants used in tailings treatment. These aren’t just afterthoughts. How you treat your tailings—how you separate solids from liquids before disposal—can affect everything from water reuse to environmental compliance. One of our partners learned this the hard way when a poorly performing flocculant led to fines from regulators due to elevated turbidity levels in discharge water. A switch to a higher-grade product, and better dosing control, resolved the issue. It was a costly lesson, but one that reinforced how chemical precision impacts sustainability.

Then there are defoamers, frothers, and pH regulators—all working behind the scenes in flotation or gravity separation processes. On a recent site visit, we observed how a seemingly minor inconsistency in pH balance was causing gold particles to remain bound in tailings. With the supplier, we helped troubleshoot the buffering agents and adjusted their application schedule. Within two weeks, recovery rates were up by 5%. That’s significant. That’s operational chemistry at work.

One thing we’ve come to appreciate is that the choice of chemical is only part of the equation. Storage, handling, staff training, and even transport protocols are just as important. Some of these substances are classified as dangerous goods, requiring specialized containers and driver certifications. Improper handling can lead to spills, injuries, or worse. That’s why we work closely with partners to ensure that every chemical we deliver is documented, secured, and accompanied by safety data sheets in languages that site workers actually understand.

We also see increasing interest in digitizing chemical dosing controls. Automated systems tied to sensor feedback can regulate how much of a chemical is added based on real-time readings. While not yet widespread in Ghana, it’s only a matter of time. And when it comes, companies who understand their chemical baselines will be the ones ready to make that shift efficiently.

This intersection of operational need, scientific accuracy, and safety is something we at JOBEX COMPANY LTD take seriously. It’s also part of what I believe earned us a nomination for the 2025 Go Global Awards in London, hosted by the International Trade Council. This November, the event will bring together companies from around the world that are navigating complex, technical environments with care and competence. To represent Ghana in that space—bringing a voice from the practical, boots-on-ground side of industrial services—is something we’re proud of.

In the end, high-impact chemicals aren’t just “supplies.” They’re precision tools. And like any tool, their effectiveness comes down to how well you understand them, manage them, and integrate them into your broader process.

Gold recovery is chemistry. And chemistry, in the field, is both science and experience.

Preparing for Mining Audits: A Checklist for Camps and Suppliers

By ATO ASEFOAH DADZIE

Few words can make a site manager sit up straighter than “audit.” Whether it’s environmental, safety, operational, or compliance-related, a mining audit has the potential to uncover weaknesses you didn’t know were there—or worse, confirm the ones you hoped wouldn’t be noticed.

At JOBEX COMPANY LTD in Ghana, we’ve supported both clients and our own teams through countless audits across the mining value chain. From sanitation checks in worker camps to material traceability in procurement files, we’ve seen what a good audit looks like—and, honestly, what a bad one feels like too.

Over time, we’ve developed a working checklist that helps us prepare without panic. Not because we expect things to be perfect, but because we believe readiness is a culture, not a one-time effort.

Let’s walk through it.

Documentation is everything It may sound obvious, but you’d be surprised how often critical records go missing. From fuel logs to safety induction sheets, from procurement receipts to waste disposal slips—auditors will ask to see what you've done and how you recorded it. If it’s not on paper (or in digital systems with time stamps), it’s like it didn’t happen. We recommend a monthly documentation review—just a half-day session to ensure everything is filed, signed, and accessible.

Walk the site before they do A physical walk-through of your camp or work area a few days before the audit can help catch issues early. Are all emergency exits labeled and unobstructed? Is the fire extinguisher mounted and inspected? Is PPE available and in good condition? Fixing these things when an auditor is standing in front of you is too late. We assign one of our team members to do a mock audit every quarter. It helps.

Know your team leads Audits are conversations, not interrogations. But if your personnel don’t know who to speak to—or worse, give contradictory information—it reflects poorly on the entire operation. At JOBEX COMPANY LTD, we designate a “point person” for each operational zone. Housekeeping knows who to call. Kitchen staff have a lead. Drivers have theirs. When everyone knows their domain and who speaks for it, it shows confidence and control.

Waste management and environmental practices Especially for international clients or partnerships, this has become a spotlight issue. Auditors want to see how camps manage greywater, how oil is disposed of, how used batteries are stored. We had one audit where a simple segregation of plastic waste earned us unexpected praise—it wasn’t mandatory, but it showed intent. Think beyond compliance. Think responsibility.

Training and awareness logs Have your staff been trained on safety protocols? Do you have a record? Even informal “toolbox talks” should be logged. We’ve found that a simple A4 binder with dated pages for daily briefings makes a big difference. It’s not complicated. It just shows consistency.

Supplier traceability Auditors may ask how you sourced certain chemicals, construction materials, or even food items. Can you prove the origin? Was the vendor vetted? Did you follow internal procurement processes? Especially in mining camps, where diverse goods are brought in daily, it’s easy to lose track. We've integrated a supplier pre-approval form into our onboarding to create a paper trail from day one.

Safety drills and first aid readiness When was your last fire drill? Who’s trained in basic first aid? Is your emergency plan posted in visible areas? Audits often include scenario questions: “What would happen if...?” Having answers, and showing staff are trained to respond, earns more credit than fancy tech ever could.

I’ll be the first to admit—we didn’t get all this right from the beginning. Our early audit experiences were a mix of stress and scrambling. But we’ve matured. And much of that growth is thanks to clients who expected better, who shared global best practices, and who challenged us to step up.

This commitment to readiness, to process, and to a culture of accountability is part of what’s helped JOBEX COMPANY LTD gain international recognition—including our nomination for the 2025 Go Global Awards in London this November. Hosted by the International Trade Council, it’s more than an awards show. It’s a gathering of companies that understand the world is watching, and that transparency builds trust.

So, are audits nerve-wracking? Sure, sometimes. But they’re also a chance to prove that your systems work, that your team is aligned, and that your operation is built to last—not just built to pass.

Telecommunication Trends for Remote Mining Zones

By Ato Asefoah Dadzie

—

Connectivity is no longer a luxury—it’s a necessity. And nowhere is that more evident than in the remote mining zones of Ghana and across the continent. As operations spread farther into previously untouched areas, the demand for dependable, high-speed, and secure telecommunications infrastructure has gone from being “nice to have” to absolutely critical.

At JOBEX COMPANY LTD, we’ve supported numerous mining camps and project sites where the first request, right after power and water, is: “Can we get stable Wi-Fi?” It’s a simple question. But the answer is layered.

First, let’s talk about what’s driving this demand.

Mining today is no longer entirely analog. Exploration data, safety systems, time tracking, inventory management, even equipment diagnostics—many of these now rely on cloud-based systems or require access to internal company networks. Engineers want to upload field readings. Managers want to hold virtual check-ins. Staff want to contact families during downtime. Connectivity weaves through every part of site life.

So what’s trending?

Satellite Internet Is Getting Smarter Traditional VSAT (Very Small Aperture Terminal) systems have long been the backbone of remote communications. But latency and bandwidth limitations often made them frustrating. Today, new generations of LEO (low Earth orbit) satellite systems—think services like Starlink—are beginning to transform what’s possible. We recently installed a satellite system for a client in a gold exploration zone near Wa, and the difference in call quality, file transfer speed, and even video conferencing was night and day.

That said, satellite isn’t always plug-and-play. Weather, topography, and data caps still need to be managed with care. And backup systems remain important.

Hybrid Infrastructure Is the Future We’re seeing a trend toward hybrid systems—where a mining site may use satellite for core data transfer but switch to point-to-point radio links or cellular repeaters for internal communications. This provides redundancy, which is crucial during emergencies or maintenance downtime. One major mine we worked with had a dual system: satellite for the camp, and a microwave relay for the processing plant. If one failed, the other picked up seamlessly.

Security Is a Growing Priority As connectivity increases, so do risks. Cybersecurity is no longer something only big corporations worry about. In remote zones, equipment can be hacked, operations can be disrupted, and sensitive exploration data can be stolen. We now recommend basic cybersecurity protocols for every camp—VPNs, encrypted routers, regular password audits. It’s not expensive. It’s just not optional anymore.

Mesh Networks for Internal Mobility Some of our most successful deployments have used mesh networks within the camp area—particularly where workers need to move freely without losing signal. These networks create a blanket of connectivity across dorms, kitchens, workshops, and offices, enabling real-time monitoring and communication. It also reduces the load on core satellite bandwidth since internal traffic stays local.

Staff Welfare and Retention This one often gets overlooked. A connected worker is a happier worker. In a mining camp where teams rotate in and out, access to internet and calls home isn’t a perk—it’s part of their mental health support. We’ve had clients report lower turnover after investing in modest but stable connectivity for their sites. Think of it as digital hospitality.

But it’s not without challenges. In rural Ghana, network equipment must contend with heat, dust, humidity, and occasional power surges. We’ve adapted by using protective housing, surge protectors, and solar backups. We’ve also trained on-site personnel to do basic diagnostics, so they don’t have to wait days for a technician to travel in.

At JOBEX COMPANY LTD, this approach—layered, practical, and built for field conditions—is what defines our service delivery. We don’t install and walk away. We monitor. We adjust. We build with failure in mind.

It’s this ethos that I believe helped earn us a nomination for the 2025 Go Global Awards, happening this November in London. Hosted by the International Trade Council, the event brings together global companies navigating real operational terrain—not just markets on paper. It’s a space for collaboration, for trading lessons learned the hard way, and for building smarter, more connected futures.

Because even in the quietest, most distant outposts—where red dust clouds the sky and the nearest town is a three-hour drive—connectivity is what makes everything else possible.
