PROCEDURE FOR PURIFICATION OF MANGANESE CONCENTRATES FROM PHOSPHORUS Russian patent published in 2010 - IPC C22B47/00 C22B1/02 C22B3/04

Abstract RU 2395601 C1

FIELD: metallurgy.

SUBSTANCE: invention refers to metallurgy, particularly to procedure for purification of manganese concentrates from phosphorus. The procedure consists in agglomeration of concentrate with sodium salts at 950-1000°C and weight ratio 1:0.4, and in successive water leaching with transfer of phosphorus into solution. Further concentrate is filtered and dried. Also leaching is carried out under effect of ultrasonic oscillations of 18·10³-22·10³ Hz per second frequency during 15-30 minutes. Finished concentrate is filtered and dried in ultrasonic fields of 18·10³-22·10³ Hz per second frequency.

EFFECT: upgraded quality of manganese concentrate by means of reducing concentration of phosphorus in it.
