Recovery of Manganese From Slimes by High–Intensity Magnetic Separation

Abstract

Production-scale application of the high-gradient magnetic separator VMS 100/2 to the recovery of manganese from the plant railings is described. It has been found that in one-stage separation the concentrate containing 25 to 28% Mn can be obtained, with the recovery of 65.6%. In a two-stage process the grade of the concentrate was 31.7% with the recovery of 55.8% The final cleaning_ of the manganese concentrate yielded a product with ihe grade of 35 to 41% Mn. *This paper is an adapted version of a paper published, originally in Russian, in Skladirovaniye utilizatisya otchodov pererabotky rud chernych metallov (Nedra, Moscow), 1991, p. 102.
