Abstract
A gold placer in the valley of the River Bolshoi Kurunakh occurs in complicated geological and mining conditions and is characterized by a highly nonuniform quality of the reserves. Modeling showed that the reserves occur in clusters distributed all over the productive sand extension. High clay content and liberal share of fine gold impede processing and reduce the output. The article offers a combined processing technology for the given placer, based on pre-concentrating of commercial mineral, and designates further research.
