01 Jig gravity separation process. 1. Ore crushing and grinding: The jig gravity separation process begins with the ore crushing and grinding stages. The raw ore is fed into the crusher to be broken into smaller particles, and further refined through the grinding equipment for better physical separation.. 2. Primary gravity separation: First, the ore is fed into the primary …

SYNOPSIS. Sishen Iron Ore Mine previously used only A-grade material (>60% Fe in situ value) from the pit for beneficiating in the DMS plant to a final product grade of 66% Fe in lump and 65% Fe fine ore. The B-grade (between 50% and 60% Fe) and C-grade material (between 35% and 50% Fe) were stockpiled separately, owing to the inability of the existing DMS plant to …
