  [PDF] The prereduction and smelting of chromite concentrate …

  SYNOPSIS The prereduction and smelting characteristics of UG-2 ore were studied and compared with those of Winterveld chromite ore. The UG-2 ore proved more reducible, and substantial prereduction (over 70 per cent reduction after 30 minutes at 1250QC) was obtained. No difficulty was experienced in the production oh high-carbon ferrochromium …
