Description
Technical field
The present invention relates to technical field of mineral processing more particularly to a kind of recovery methods of white tungsten fine ore.
Background technique
In recent years, some mine enterprises were backward in technique due to sorting, and the valuable mineral in ore cannot be made full use of, can only
Single is isolated from ore or a few is easy the valuable mineral sorted, and some valuable refractory minerals are not divided
From companion tailing abandons together, and most of mineral resources is caused to waste.Therefore, the comprehensive reutilization of tungsten resource is even more important.
Currently, the technical method of China's recycling scheelite is mainly method for floating, in floating agent used in floatation,
Collecting agent is based on fatty acid collecting agent, and regulator is based on sodium carbonate and sodium hydroxide, and inhibitor is with waterglass and Yi Shui
Based on derivative medicament based on glass, the method for selecting above-mentioned floating agent to carry out flotation to scheelite is looked forward in many mines in China
Industry has all obtained good application.
It is preferably separated from the tailing containing more fluorites, low-grade scheelite however, existing method for floating can not achieve
Scheelite out.
