Phosphate flotation dressing
Phosphate flotation dressing
Positive Flotation Process
Direct flotation is the use of effective inhibitors to inhibit gangue minerals, the use of collectors to enrich phosphorus minerals in foam, and can be applied to low-grade phosphate rock, including magmatic rock apatite and sedimentary metamorphic phosphate. Rock ore;
Reverse flotation process
It is mainly used for the separation of phosphate rock and dolomite. The dolomite is floated with a fatty acid collector in a weakly alkaline medium, and the phosphorus mineral is enriched in the tank. The advantage is that the normal temperature flotation is achieved, and the product granularity in the tank is achieved. Thicker is good for product post-processing;
Double reverse flotation process
Double reverse flotation is to make the surface of the silicate positively charged under alkaline conditions and use the anion collector to achieve the separation of the target mineral, that is, first float the dolomite, then reverse flotation silicate, the product in the tank is For heavy concentrates, the line can be operated under normal temperature and coarser particle size conditions.
