METHOD FOR EXTRACTION AND PROCESSING OF MOLYBDENUM-CONTAINING ORES Russian patent published in 2015 - IPC B03B9/00 E21C41/26 C22B34/30 

FIELD: mining.

SUBSTANCE: invention refers to the mining industry and may be used during extraction and processing of molybdenum-containing ores. A method for extraction and processing of molybdenum-containing ores involves open-pit field zoning, outlining of solid ore sections different by processing characteristics, selective extraction on the outlined sections with ores allocation to separate the flow from the zones with increased molybdenite oxidation and its direction to luminescent separation. A powellite enriched product of separation after its size degradation is directed to bulk floatation obtaining a rough molybdenic concentrate. Then after molybdenite oxidation in the rough concentrate, powellite is leached in an environment of a molten mixture of chloride and sodium silicate. The tail product of separation after its size degradation is directed to bulk floatation obtaining the molybdenic concentrate.

EFFECT: increasing a level and quality of molybdenum extraction to the end product from balance molybdenum ores with higher degree of molybdenite oxidation.
