METHODS OF EXTRACTING WOLFRAM FROM TECHNOLOGICAL WASTE OF WOLFRAM CONTAINING ORES

Abstract

Extracting tungsten from technogenic waste (lying tailings of processing plants and waste cakes), processing concentrates and extracting useful components from them with subsequent use as secondary raw materials is one of the urgent tasks in the field of deep and complex processing of mineral raw materials. This task has several priorities. Firstly, the metal extracted from secondary raw materials is significantly cheaper than the metal extracted from ore due to a number of technological conversions in processing. Secondly, after removing metals from waste, the latter can be usefully utilized into finished products, creating a waste-free technology.
