Carbon-in-Leach (CIL) is conventionally used in gold processing operations when preg robbing components are present in the ore. CIL process is becoming attractive even in
Degradation of cyanide occurs in the tailings water discharge to slimes dams. The degree of degradation or cyanide loss in the water recovered depends on
A unique collector dispersion techniques was developed and used to improve the flotation rate and recovery of coarser and ultrafine coal-rich particles in the froth
The bacterial oxidation (BIOX) process for the pre-treatment of refractory ores for gold recovery was developed by the Genmin Process Research laboratory. Early work started
In the past mining accidents were often a consequence of poorly designed equipment and inefficient mining systems. As mining equipment and technology has become better
In situ recovery of minerals has great potential as a mining technology to mine deposits that might otherwise be overlooked by conventional techniques. Some hard-rock
The origins of AEROPHINE 3418A promoter date back to the 1960’s, when it was established that sulfide mineral collectors based on phosphine chemistry demonstrated efficacy.
Blasting plays a key role in all facets of operations. Obviously, drilling and blasting costs are determined by blast design, but the downstream costs that
In many deep mines, the design of a ventilation system to satisfy the airflow requirements might be difficult to implement and expensive to maintain. The
The Bureau of Mines’ Intermountain Field Operations Center, Denver, CO; and the Bureau’s Salt Lake City Research Center, Salt Lake City, UT, jointly studied domestic
