Enrichment of Cobalt Values by Dry Magnetic

By processing the low-grade siliceous ore on a dry belt magnetic separator, a product with 47% Mn at 60% recovery could be obtained. It was observed that along with manganese the cobalt value gets enriched (~Co: 0.38%) more than four times in comparison to the feed.
