Extraction of copper from low grade ores
WebWhich solvent is used for extraction of copper from its low grade ore? The most common solvent is 510% sulfuric acid in water. Diluted smelter acid can provide this at low cost. This can dissolve a number of copper minerals, not just the oxide (Eqs. 13.4513.48). The average grade of copper ores in the 21st century is below 0.6% copper, with a proportion of economic ore minerals being less than 2% of the total volume of the ore rock. Thus, all mining operations, the ore must usually be beneficiated (concentrated). The concentrate is typically sold to distant smelters, although some large mines have smelters located nearby. Such colocation of …
