| titleOfInvention | Process of flotation concentration of carbonates in a closed-circuit water recycling |
| abstract | The invention relates to the enrichment of minerals and can be used in the complex use of apatite-rare metal carbonatites. The goal is to increase the extraction and quality of apatite concentrate and reduce the consumption of apatite collector. The original ore is crushed, treated with alkaline modifiers, lignosulfonates and a collector containing N-acylamino acids. Then apatite is floated to form a concentrate and chamber product. Sequential flotation of carbonates and mica is carried out from the chamber product. The final products thicken the circulating waters after the apatite and carbonate flotation are conditioned with magnesium sulfate and sodium hydroxide. In this case, the mass ratio of magnesium sulfate, sodium hydroxide and suspended particles is maintained in the range from 1: 0.75.8 to 1 1:12, respectively. Purified particulate circulating waters are combined with neutral circulating waters of mica flotation and returned to the process. The use of the method increases the recovery of apatite by 4% with an increase in its content in the concentrate by 1.0-1.5%. This reduces the consumption of talactam 1.5-2 times. WITH |
