Copper extraction refers to the methods used to obtain copper from its ores. The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors. As in all mining operations, the ore must usually be ...
If it's built, the smelter would be the only one of its kind west of the Mississippi River. Potential uses of the silicon metal include aluminum and computer-chip manufacturing. HiTest would like to have the smelter operating by late 2019, but getting there will be a test of the current climate in Washington for large-scale industrial projects.

OSHA conducted sampling during abrasive blasting when both silica sand and staurolite (containing about 2% crystalline silica) abrasives were used. Although the airborne exposure levels outside the helmets were still well over the calculated permissible exposure limit (PEL) when staurolite was used, they were reduced by up to 98%.
