[Introduction]: According to different ore properties of phosphate, Xinhai designs many processes for it such as flotation, gravity separation, chemical leaching, combined dressing, photoelectric sorting, etc. Flotation is widely used in phosphate including direct flotation, reverse flotation, reverse flotation and flotation, and double-reverse flotation process.
[Improvement]: Phosphate Flotation Product Line is applied for complex structure phosphate with fine particle distribution, closed embeddedness relationship, difficult monomer dissociation, etc.
Direct flotation inhibits gangue minerals by effective inhibitors, and the phosphorus mineral is enriched in foam by collecting agent. This process is suitable for low grade phosphate ores including magmatite type apatite and sedimentary metamorphic type phosphorite ore.
Mainly used for the separation of phosphate and dolomite; dolomite is collected with fatty acid collector in weak alkaline medium, and the phosphorus mineral is enriched in the groove. The biggest advantage of reverse flotation process is the realization of the normal temperature flotation.
In alkaline conditions, double-reverse flotation makes the silicate surface positively charged, and the anionic collector separates minerals meaning floating dolomite firstly, and then reverse floating silicate; the product is heavy concentrate in groove; the production line can be carried out at normal temperature and coarse grain condition.
