Solid State Reduction of Preoxidized Chromite-iron Ore

Chromite ore is an essential raw material in producing ferrochromium alloys. At present, almost all of the ferro-chromium alloys production is operated by means of the electric furnace smelting process, which generally applies high grade chromite ore as its feed material.1,2) However, a decreasing availability of traditional lumpy ore for smelting

Processing, smelting and refining gold World Gold Council

For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide as laid out in the International Cyanide Code. Gold refining

Direct Smelting of Chromite and Laterite Ores with Carbon

Chromite and laterite ores from local sources were smelted in a vertical tube furnace with activated carbon as reducing agent at 1400°C to 1550°C using graphite crucible under argon atmosphere. It is shown that the grade and composition of the ore are the main factors determining the feasibility of smelting a mixture of chromite and laterite ores to produce a Fe-Ni-Cr crude alloy.
