Copper Mining and Extraction: Oxide Ores

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 | Definition, History, & Facts ...

The search for copper during this early period led to the discovery and working of deposits of native copper. Sometime after 6000 bce the discovery was made that the metal could be melted in the campfire and cast into the desired shape. Then followed the discovery of the relation of metallic copper to copper-bearing rock and the possibility of reducing ores to the metal by the use of fire and ...

Copper Ore Usage | Black Desert Online

Jul 23, 2017· Hey guys, I just wanted to ask what are the common or most efficient ways to use Copper Ore mined by workers. I have been processing them to shards, which I then deposit back into my storage. However, it's a huge loss: I take out 500 copper ores, worth around $500 each. After heating them into shards, I get around 150 shards which are $1000 each.

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.

Copper - Wikipedia

The concentration of copper in ores averages only 0.6%, and most commercial ores are sulfides, especially chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4) and, to a lesser extent, covellite (CuS) and chalcocite (Cu 2 S). These minerals are concentrated from crushed ores to the level of 10–15% copper by froth flotation or bioleaching.
