Canadian mining company writes USA environmental report

By Shardell Joseph

Documents revealed that the Trump administration has allowed British Columbia-based mining company, Midas Gold, largely influence the writing of an environmental report. According to conservation group, Earthworks, which obtained the documents, the input Midas Gold will contribute will aid government approval for its Idaho gold mine project.

An Idaho statesman claimed that access to the environmental report proposed open-pit gold mines in central Idaho, USA, which were previously rebuffed from the Forest Service.

The report, called a biological assessment, would typically be written by the Forest Service or an independent contractor. Its purpose is to examine the potential effect the open-pit mines would have on salmon, steelhead and bull trout protected under the Endangered Species Act.

In February 2018, internal documents show the agency denied Midas Gold's request to participate as a non-federal representative in writing the assessment because the massive project would likely harm protected fish. However, by October 2018, Midas Gold was both participating and leading the writing of the document.

The company claims that Idaho there is over 113 million grams of gold and more than 45 million kilograms of antinomy at the Idaho site. The company plans on additional mining in the two open pits already there and to create a third open pit, doubling the size of the area utilised for the mining. They say they will restore ‘much of the area’ when they finish mining.

Design and Construction of Rock Crushing Machine from Locally Sourced Materials for Indigenous Use-Crimson Publishers

Design and Construction of Rock Crushing Machine from Locally Sourced Materials for Indigenous Use by Ocheri C in Aspects in Mining & Mineral Science

The design and construction of a prototype rock crushing machine was performed this is with a view to ensuring that the designed crusher is capable of crushing rocks, lime stone and solid minerals for indigenous use. The research work was tailored mainly on the design and production of locally fabricated rock crushing machine for indigenous use. To accomplish the entire work within the scope of time therefore necessary parameters were considered, the following activities were also performed according to the procedures discussed in the research work. Available crushing machines in mines were studied to ascertain their associated prospects, challenges and problems. Extensive research was carried out using existing data and information-based literature survey that was used. Detailed design analysis was performed with a view to catering for all the identified challenges. A prototype was constructed to evaluate the design analysis carried out. Rock crushing machines are highly essential in the mineral processing and extractives industries. The few machines in use today in most industries are imported, thus raising the cost of production and depleting foreign exchange earnings. Locally designed rock crushing machines have lot of benefits which translate to job creation, revenue generation and wealth creation. This provides amble opportunities for Government, stakeholders, corporate bodies and individual alike to own such machine since they are affordable since they are manufactured locally which signifies that such machines could be attended to easily by the manufacturer in case of any failure or malfunctioning. It reduces importation, thus fighting the depleting foreign exchange earnings.
