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.

Smelting and Refining Operations

Primary smelting and refining produces metals directly from ore concentrates, while secondary smelting and refining produces metals from scrap and process waste. Scrap includes bits and pieces of metal parts, bars, turnings, sheets and wire that are off-specification or worn-out but are capable of being recycled (see the article "Metal ...

How is Iron Refined from Ore? (with pictures)

 · Iron ore consists of oxygen and iron atoms bonded together into molecules. To create pure iron, one must deoxygenate the ore, leaving only iron atoms behind, which is the essence of the refining process. To coax the oxygen atoms away from the ore requires heat and an alternate atomic partner for the oxygen to bond to.

Extraction of Non-ferrous Metal-

Once the ore is mined, the raw ore is firstly crushed and milled to expose auriferous minerals (mainly native metal). Before leaching, the grain size is prepared to 0.4mm, 74μm or 44μm depending on the leaching test result. In case the raw ore is highly oxidized or of too much slurry, hydrocyclone and thickener are used to remove slurry.
