Developing the Technology of Complex Adoption of Phosphate Rare-Earth Metal Ores from the Tatarskoe Deposit

摘要

Results of research into obtaininga conditioned apatite concentrate from the intermediate product of electrical separation (IPES) of the ore-dressing plant of phosphate-rare earth metal ores from the Tatarskoe deposit (Krasnoyarsk krai) are described. The structural and crystalline features of minerals entering the IPES and the effect of reagents on them are investigated. To develop the flotation mode of apatite from the IPES, experiments are statistically planned with the use of the multilevel factorial plan 3~3/9. An apatite concentrate with a P_2O_5 content of 38.4% with a recovery of 95.7% is obtained.
