Abstract:
With higher environmental protection requirement and gold resources becoming low-grade,fine and impure,mineral processing is more challenging.Therefore,tailings utilization as resources becomes a hot study topic.In the study of gold extraction from roasting cyanide tailings,according to the different embedding status of gold,gold extraction methods are classified as iron oxide inclusion gold extraction,silicate inclusion gold extraction and comprehensive gold extraction as far as the effectiveness of inclusion disintegration in roasting cyanide tailings goes.At the same time,the advantages and disadvantages as well as its applicability of each method are analyzed,providing reference for the selection of gold extraction method for roasting cyanide tailings.
