In beneficiation method, it is difficult to effectively separate beryl and spodumene when magnetic separation or gravity separation method is used. Therefore, flotation can effectively separate beryl and spodumene.
Complex multi-vein type fluorite ores include quartz-type fluorite, calcite-type fluorite, barite-type fluorite and sulfide mineral-type fluorite. The beneficiation process is generally based on flotation.
There are many kinds of quartz sand beneficiation and purification processes, such as: scrubbing, flotation, magnetic separation, gravity separation, acid leaching process, etc. The following are mainly the quartz sand magnetic separation process and related mineral processing equipment.
The zinc powder replacement process for gold extraction develops on the basis of zinc silk replacement process. Nowadays, it is the main method of gold extraction from cyanization pregnant solution which contains gold. Its process can be divided into the following stages: grinding and classification, concentration and dewatering, leaching and washing, pregnant solution purification, pregnant solution deoxidation and zinc powder replacement.
