Copper Mining Info The above flowsheet shows a basic copper mine process from mine to metal There are two distinct types of copper ore the sulfide ore and the oxide ore The sulfide ores are beneficiated in flotation cells while the oxide ores are generally leached First the copper ore from a open pit mine is blasted loaded and Prospecting and exploration are precursors to mining and often occur simultaneously together they can take two to eight years to complete and may cost from $500 000 to $15 million overall Prospecting is the process of searching the region for mineral deposits Historically prospectors would explore a region on foot with a pick and shovel
