Complex-structure gold placer mining in Yakutia

Open publisher page 2 citations

Abstract

The gold placer in the valley of the River Bolshoi Kuranakh occurs in complicated geological and mining conditions and holds gold of highly nonuniform quality. Modeling shows 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 specifies further research.
