The recovery of ferrochrome from slag at Zimasco

Nov 01, 1997 The metal was crushed to coarse sizes (<75 nun) at which metal concentrate grades of about 93 per cent could be obtained from magnetic separation and hand-sorting to remove unliberated metal. The grade could be improved by scrubbing or attritioning of the metal to remove surface coatings of slag.

PRODUCTION, CHARACTERISTICS AND USE OF

The ferrochrome slag products are granulated slag as well as classified slag products made by crushing and screening. The main part of slag is granulated. The cr ushed and screened slag products are produced from air magnetic separation. The first stage of slag processing is crushing and sc reening the feed material to fractions
