Generally speaking, copper ore can be divided into three categories: copper sulfide ore, copper oxide ore and natural copper. Before the beneficiation of copper ores, …
Extraction of copper from copper pyrite (C u F e S 2) involves : crushing followed by concentration of the ore by froth-flotation; removal of iron as slag; self-reduction step to produce 'blister copper' following evolution of S O 2; refining of 'blister copper' by carbon reduction
The rotary scrubber is also called trommel scrubber, or drum washer/ scrubber; it can effectively wash and screen ore with high mud content/ solid and get cleaner products. The trommel scrubbers are mainly applied for washing gold, diamond, and other ore (including manganese, copper, tantalum-niobium-tin, iron ore, silica sand, fluorite, etc.).

But, aluminum vs copper crush washer, how do they differ? Copper crush washers are more durable than aluminum crush washers. Also, copper has a higher melting point in terms of heat resistance, making it better than aluminum. Additionally, aluminum is more corrosion-resistant and lightweight but costlier than copper.
