The major advantage of Carbon in Pulp is not the reduction in the use of zinc dust but rather the impact on the dewatering requirements. Using carbon allows the gold to be recovered on coarse pellets (16 mesh) of activated carbon.
Stibnite (Sb2S3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries. The metal also finds applications in solders and other alloys. Antimony trioxide is the most important of the antimony compounds and is primarily used in flameretardant formulations.
