Innovations: Introduction to Copper: Mining & Extraction
The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore. By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals. Such ores originate from sulfur-bearing volcanic magmas, which have separated into metal sulfides and siliceous melts.
Production of a Cobalt–Nickel–Iron Alloy from Low-Grade Ore
Abstract. A novel way of producing a cobalt–nickel–iron alloy containing 55% Co, 9% Ni, and 36% Fe from an oxide ore with 1.8% copper, 0.26% cobalt, 2.8% iron, and 0.08% nickel has been established. The ore is initially treated hydrometallurgically via leaching and precipitation steps to upgrade copper, cobalt, iron, and nickel as a bulk ...
