Cobalt Flotation Studies were conducted on ores from the Viburnum trend in southeast Missouri. The Viburnum trend deposits occur along the flank of the St.
The Bureau of Mines, in its continuing efforts to improve productivity and enhance the workplace environment of hard-rock underground mines, has investigated mechanical excavation techniques
Objective: Provide a low-maintenance, reliable means of generating bubbles and controlling bubble size for column flotation. Approach: Commercial sparger systems used in flotation columns to process minerals
Objective: Use water-jet-assisted cutting technology to reduce the exposure of mine workers’ to respirable dust. Approach: Install water-jet-assist on mining machines and evaluate its impact on respirable
The use of water jets to augment mechanical rock cutting has advanced greatly since the discovery a decade ago that water jets diminish the forces
The Bureau of Mines has sponsored numerous high-risk research programs over the past decade to improve productivity and health and safety in underground coal mining
Stop Mining Flat Deposit In the previous topic you were introduced to the different methods adapted to mine underground deposits. Well the basic elements are
Zeolites are crystalline aluminosilicates of the alkaline and alkaline-earth metals. They possess many desirable ion- exchange, molecular sieving, and catalytic properties, which make them valuable
Suspended solids are a common impurity in mine water. Mines rely mainly on flocculation and settling for solid removal, but this can be unreliable owing
When certain insulating materials are decomposed by heat, highly explosive gases can be released. These insulating materials cannot be used within enclosures containing high-voltage circuits
