Nickel Smelting and Refining IFC

In flash smelting, dry sulfide ore containing less than 1% moisture is fed to the furnace along with preheated air, oxygen-enriched air (3040% oxygen), or pure oxygen. Iron and sulfur are oxi-dized. The heat that results from exothermic re-actions is adequate to smelt concentrate, producing a liquid matte (up to 45% nickel) and a fluid slag.

Behavior of platinum metals during sulfide copper-nickel

Current production and investigation data allow rather correct assessment of nickel, copper, cobalt, iron and sulfur behavior during the pyrometallurgical processing of various copper-nickel concentrates. At the same time, behavior of platinum and noble metals on main pyrometallurgical stages is still insufficiently investigated. There are shown the investigation results of distribution of

extraction of copper other sulfide ores auto-spec

The techniques for extraction of copper from oxidized ores are quite different from those employed for the sulfide ores. The oxidized ores, consisting of the silicates, carbonates and sulfates, are treated by several methods, all involving some form of leaching of the crushed ore with sulfuric acid to produce impure solutions of copper sulfate.

This is crushed, ground and separated into metallics, nickel sulphides and copper sulphides by magnetic separation and flotation in the Matte Separation Plant. All of the precious metal bearing metallics and some of the nickel sulphide are sent to the Copper Cliff Refinery. The remaining nickel sulphide is roasted in fluid bed roasters.
