1. Beneficiation of phosphate rock: Beneficiation of phosphate rock is the first step in the processing of phosphate rock, which aims to separate useful minerals from impurities in phosphate rock by physical and chemical methods. Common beneficiation methods include gravity separation, flotation and magnetic separation. Gravity separation uses the density difference of minerals in the ore for separation, flotation uses the buoyancy difference of minerals in the ore for separation, and magnetic separation uses the magnetic difference of minerals in the ore for separation.

2. Crushing and grinding of phosphate rock: phosphate rock after beneficiation, need to be crushed and grinding treatment, in order to better release the useful minerals in the ore. Crushing is usually used jaw crusher, cone crusher and other equipment to break phosphate rock into appropriate particle size. Grinding is the use of large mill production and processing phosphate powder machine to fine grind the crushed ore, so that it meets the required fineness requirements.

3. Leaching of phosphate rock: Leaching is a key step in the processing of phosphate rock, through which useful ingredients such as phosphate can be dissolved from the ore. The commonly used leaching methods include acid leaching, alkali leaching and oxidation leaching. Acid leaching uses an acidic solution to dissolve the phosphate, alkaline leaching uses an alkaline solution to dissolve the phosphate, and oxidative leaching uses an oxidizing agent to dissolve the phosphate.

4. Precipitation and filtration of phosphate ores: After leaching, the solution of useful components such as phosphate needs to be precipitated and filtered to separate the solid phosphate products. Precipitation is the use of precipitating agent to convert the phosphate component of the solution into a solid precipitate, and filtration is the separation of the sediment from the solution by filtering equipment.

5. Drying and sintering of phosphate rock: After the sediment is filtered, it needs to be dried and sintered to get the finished phosphate product. Drying is the use of drying equipment to evaporate the water in the sediment, and sintering is the drying of the sediment at high temperature sintering, so that it forms dense phosphate particles.

6. Phosphate ore tailings treatment: phosphate ore processing process will produce a certain amount of tailings, tailings contain unextracted minerals and impurities. In order to reduce environmental pollution and waste of resources, tailings need to be treated. The common tailings treatment methods include tailings stacking, tailings recycling and tailings comprehensive utilization.
