Fire refining is used both in primary copper extraction and in secondary copper extraction (recycling). In this process, copper impurities are converted into an oxidic form by selective oxidation at high temperatures and extracted as slag. Depending on whether fire refining is based on solid starting materials – blister copper in solidified form or scrap – or liquid blister copper, a

The process varies slightly depending on the type of ore that is being mined. Sulfide ores are first put through a jaw or gyratory crusher to reduce the rocks to about 7 - 8 inches. This material is then fed to a secondary grinder that further reduces the size to about 1 - 2 inches. The next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the
