Silver Flotation Production Line

The silver flotation process of Xinhai includes three kinds of methods: flotation, flotation & gravity separation, flotation & cyaniding. While the flotation & cyaniding method is the most important process among the three. 

The silver concentrate can get in the process of flotation, then regrinding to the next process including cyaniding and leaching, countercurrent washing, zinc powder replacement, and silver ingot can finally get after the last process of electrolytic dissociation. Thus the process is characterized by high recovery and economic benefits.

The silver flotation process is mainly applied for the recovery of silver and associated metallic minerals, including two categories: one is silver & gold, the other is copper, lead, and zinc associated.

Gold Heap Leaching Production Line

Heap leaching (HL) is a flexible and economic gold ore processing method used to extract gold from low-grade gold ores. In this process, the ore is firstly crushed to fine particles. By spraying the leaching solution to the large piles, the gold-containing solution is leached. Then used the gold processing method of carbon adsorption, zinc powder displacement device, and so on to separate gold from the liquid.

The heap leaching process is always used for low-grade ore, small gold mines, or both. These ores can not be processed by using the conventional gold ore processing method.

Gold CIL Production Line

Gold CIL process (carbon in leach) is an efficient method of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, the CIL process lowers the gold mining operation cost and increases the gold recovery rate to 99%, which is the first choice of modern gold mining and gold beneficiation plant.

CIL mainly applies for the process of above 1g/t grade gold ore and gold ore with large bearing ore volume: silver, platinum, copper, etc. And CIL has a better performance in extracting these minerals at the same time.

Gold Flotation Production Line

Flotation is widely used in gold processing. In China, 80% of rock gold is processed by flotation. The flotation process maximizes the enrichment of gold into sulfide minerals. The tailings can be directly discharged. Flotation in gold mines has low beneficiation costs. Gold Flotation Process is used to process fine gold, sulfide gold-containing quartz ore, multi-metal gold-containing sulfide ore, and carbon-containing ore.

Three Operating Guidelines to Teach You How to Properly Operate Grinding Equipment

As the important equipment in the whole production line of a processing plant, the grinding equipment undertakes the heavy responsibility of grinding operation. But it’s also well-known that grinding equipment wears out a lot, which requires us not only to maintain it regularly but also to pay attention to the daily operation of grinding equipment.

Then, in the daily operation, how should the ball mill operator ensure the normal operation of the equipment? Here, we summed up three grinding equipment operating guidelines, which are briefly summarized as “equal feeding, large sand return, and high concentration”. Properly following these three operational guidelines will prolong the service life of the grinding equipment and help to achieve the ideal grinding effect.

1. Equal Feeding 2. Large Sand Return 3. High Concentration

The above three operating guidelines of grinding equipment briefly summarize the points that should be paid attention to during the operation of grinding equipment. The core behind them lies in the balance between input and output efficiency. Operators of grinding equipment need to improve their operational skills, timely respond to various conditions of grinding equipment, and ensure the smooth operation of the whole grinding process.

How to Separate Lead and Zinc Ores?

Among many minerals, lead and zinc ores are difficult to be separated. And totally, lead and zinc have poor mines than rich mines and with the complicated component. It is an important topic to research how to separate lead and zinc ore in high efficiency.

Now, the lead and zinc minerals that can be used for the industry are mainly galena, blende, bonamite, cerusite, and so on. According to the degree of oxidation, lead and zinc minerals can be classified into sulfide lead and zinc ores, oxidized lead and zinc ores, and mixed lead and zinc ores. We will analyze the processing technology from the degree of oxidation.

What Factors Would Affect Quartz Flotation Processing Plant?

Quartz flotation is one of the common beneficiation methods for quartz purification. Importantly, ignoring the following factors would reduce the quartz flotation efficiency greatly.

There are three factors needed to take into consideration in quartz flotation processing plants. Mechanical is the first factor, such as the type of flotation machine, airflow state, slurry flow state, tank composition, etc.; the second factor affecting quartz flotation is human operation as feeding speed and temperature, etc.; the third factor is the chemical factor---flotation reagent.

We at Xinhai, have not only been focusing on developing the one-stop solution for quartz flotation processing plant but also on our capabilities to help customers optimize the operation of their units.

Guide of Gold Processing Equipment

The gold ore has a high mining value, the gold processing technologies are more complex, and the gold processing equipment used is not the same.

At present, the common gold processing technologies mainly include the cyanide leaching method, flotation method, and gravity separation method. That is, through the crushing, screening, grinding, and classification, the ore is sent to the various gold processing equipment (leaching agitation tank, flotation cell, gravity separator) for separation.

The concentrate obtained by the cyanide leaching, gravity separation, and flotation are smelted by the chemical methods, and the product is finally made into the finished gold. Below, we will mainly explain the gold processing equipment used in the different stages of gold processing.
