How Mining Works - Resolution CopperOnce ore comes out of Resolution Copper's underground mine, it's processed to separate the copper from the rock before it is sent to be smelted and refined into 99.99% pure copper – ready to be manufactured into a variety of products. The process works like this: A wet grinding process turns the crushed rock into a fine.3. Processing of Copper OreThe next step is to feed the crushed ore into a wet grinding process in tumbling mills. These mills contain the ore, water and steel balls and further reduce the particles to the optimum size for the flotation process which follows. About 80% of copper from ore is generated using flotation, smelting and refining. Oxide ores are.
