Ore Beneficiation
Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.

The gravity separation separator commonly used for beneficiation of galena is a jig machine. For the coarse-grained galena, we can use the AM30 jig machine, and the selected size of this jig machine can reach 30mm. For that fine-grained galena, we can use the 2LTC-6109/8T jig machine. This jig machine is aimed at 0-8mm fine minerals.
