New milling methods, undertaken in order to recover larger quantities of low grade ore, caused the smelting industry to suffer from the mid1890's well into the twentieth century. By 1920, the Durango plant, one of only two American Smelting and Refining Company facilities remaining in the state, was working at low capacity, with rarely more ...

Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has remained dominant for over 130 years because of its selectivity and feasibility in the mining industry. For this reason, the industry has been adjusting its methods for the extraction of gold, by ...

the mine site, followed by additional crushing at the mill. The crushed ore is mixed with water and initial flotation reagents to form slurry. The ore is then ground in rod and ball mills. The slurry may also be ground in autogenous mills (a mill where the ore acts as the grinding medium) or semiautogenous mills (steel balls are added to the ore).
