low grade copper ore processing plant mexico

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining

    copper processing: the quest for efficiency at scale | e & mj

    It is no surprise that both GHG emission intensity and energy intensity increase as ore grade decreases. There is a point of inflection, where below an ore grade of around 0.5% copper, the intensity of both metrics rises sharply.” Given that many mines are fast approaching, if not already tackling, similar grades, this is a pressing problem
