Abstract

The invention discloses a skarn type tungsten ore beneficiation method. Tungsten concentrates are finally obtained through the steps of raw ore levigation, quick floatation of coarse particles, middling regrinding, quick scheelite flotation, medium grain floatation, fine grinding, fine grain floatation, centrifugal reselection of middlings and the like. Separation indexes of separated skarn type tungsten ore are good, and the grade and recovery rate of the tungsten concentrates are high. The skarn type tungsten ore beneficiation method is stable, efficient, good in separation effect, high in adaptability, high in recovery index, capable of achieving low production cost and suitable for application and popularization.

Description

technical field [0001] The invention belongs to the field of mineral processing, in particular to a mineral processing method of skarn type tungsten ore. Background technique [0002] Tungsten ore is mostly stored in skarn-type deposits, which leads to complex types of gangue minerals derived from ore bodies. Typical gangue minerals such as mica, feldspar, fluorite, epidote, and chlorite have high content and can be Good buoyancy, strong adsorption capacity and severe mudification, easy to enter the tungsten beneficiation process, difficult to disperse and suppress, and affect the recovery of tungsten ore dressing; Difficult to choose. Based on such reasons, the existing tungsten ore mainly adopts two methods for recycling, one is the "Petronov method" based on flotation, which uses sodium carbonate as a regulator, water glass as an inhibitor, and fatty acid as a trap. The collector is used for normal temperature flotation to obtain higher grade (about 2%) tungsten coarse ...
