PROCESS FOR TREATING ANODE MUD, ANTIMONY-CONTAINING VOLATILE SLAGS AND DUSTS

摘要

The process for the processing of anodic sludges of stiff and volatile dusts with a content of Sb of 30.60% and variable contents of Pb, Bi, Cu, Ag, Au according to the invention by the metal-thermal reduction for the production of Sb collectors, Pb-Bi-Cu-Ag-Au, which is usually processed in order to increase the extraction yields of the elements contained in the treated batch, performs partially reducing at 750-950 ° C the anode sludge of the slags and volatile dusts, using as Sb-Bi-Pb-Cu-Ag-Al alloy reductant from previous boreholes with more than 20% Sb and with Ag + Au content below 17% in the case of anodic sludge treatment, and ranging from 2 ... 7 %, in the case of the processing of rubble and volatile volatile dusts and added in the proportion of 5-30% of the quantity of materials subjected to metal-thermal treatment.
