Nov 07, 2018· The resulting copper from this step is known as blister copper. Blister copper undergoes further firing and purification to remove any remaining impurities. One of the main side effects of the copper smelting process is the production of waste. Refining copper results in three and a half times as much waste as the amount of copper produced.

A typical copper ore contains between % and % copper. A high grade ore produces a high yield of metal. A low grade order produces a low yield of metal. Copper can be extracted from sulfide ores (usually higher grade ores) by direct smelting. The earliest evidence of copper smelting occurs in Serbian artefacts dating from around 5000 BC.

including the environmental fate of the materials that entered the smelting process. The smelting process involves separating the target metal (the metal of value) from naturallyoccurring impurities. A smelter uses heat and oxygen to accomplish this. For example, the El Paso smelter processed predominantly copper which arrived at the
