Current equipment and technologies for high-effective extraction of fine-grain gold out of placers, ore, and man-caused raw materials of Russia

摘要

Efficient fabrication routes and equipmentto extract fine-grain gold not only out of placers, butalso out of complex ore of non-ferrous, rare, and ferrousmetals have been developed. The man-caused raw materials,i.e. stale waste of concentrating mills and waste ofelectronic industry, can be considered as a sizable source of noble metals.
