open pit: 90% of ore is mined by this method. ores near the surface can be quarried after removal of the surface layers. the ore is treated with dilute sulfuric acid. this trickles slowly through the ore dissolving copper to form copper sulfate. the copper is recovered by electrolytic refining.copper ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about kg of copper per 1,000 kg of ore copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.phytomining is used to extract copper from soil containing its ore. plants are used to absorb metal compounds such as copper compoundsthis is not enough to make it commercially viable to extract the rock. copper mines are only set up where there is more than of copper per tonne of rock ideally, the figure should be closer to 2%. the flow chart shows you how copper is extracted from its ore feb 21, 2012 ore process flow diagram of copper sulfate process; print. flow diagram of copper sulfate process. posted at:november 15, 2012 4.8 3874 ratings process flow diagram sodium sulfate pag. copper sulphate copper sulphate can soluble in water and diluted acetic acid. the solution appears as weak acidity.
