Phosphate ore stage grinding+stage beneficiation process

Phosphate ore stage grinding+stage beneficiation process

The phosphate ore stage grinding stage beneficiation process is a process flow used to treat phosphate rock ores containing both colloidal phosphate ore and apatite. The main purpose of this process is to reduce grinding energy consumption, prevent over crushing, and improve the flotation environment.

Phosphate ore stage grinding+stage beneficiation process

  • 1.Ore crushing:Crush the phosphate rock ore to a suitable particle size for subsequent processing.
  • 2.Stage grinding:The crushed ore is subjected to stage grinding, which involves coarse grinding first and then fine grinding. The purpose of stage grinding is to achieve better dissociation of useful minerals and gangue minerals in the ore, thereby improving the flotation efficiency.
  • 3.flotation:Flotation treatment is carried out on the slurry after stage grinding to separate useful minerals such as collophane and apatite. During the flotation process, it is necessary to add appropriate flotation reagents to improve the flotation efficiency of useful minerals.
  • 4.Concentrate processing:Further processing of the flotation concentrate, such as concentration and filtration, is carried out to improve its purity and quality.

Technological advantages

  • 1.Reducing grinding energy consumption: Through stage grinding, the particle size of grinding can be more concentrated, thereby reducing grinding energy consumption.
  • 2.Prevent over crushing: Stage grinding can prevent the ore from being excessively crushed during the grinding process, thereby protecting the integrity of useful minerals and improving flotation efficiency.
  • 3.Improving the flotation environment: Through stage grinding, useful minerals and gangue minerals in the ore can be better dissociated, thereby reducing the interference of gangue minerals on the flotation environment and improving the flotation environment.
  • The phosphorus ore stage grinding stage beneficiation process is an effective method for processing phosphorus ore. It can reduce grinding energy consumption, prevent over crushing, improve flotation environment, and thus improve the quality and purity of phosphorus ore.

Typical beneficiation plant

Hubei Dayukou Phosphate Mine: The useful minerals in the ore are collophane and apatite. collophane is closely bound to vein minerals and has a finer embedded particle size. The specific process is as follows:
