An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The ore grade, or concentration of an ore mineral or metal, as ...

How copper is made material, used, processing, steps . The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
In this experiment we will be measuring the concentration of copper sulphate solutions. However, due to the light blue colour of copper sulphate, the colour fades out by the time we'll have made a 10% concentrated solution.
The acid leaching of copper oxide ores generates a vertical acid concentration gradient in the ore heap, which is not generally observed in sulfide deposits. Shafer et al have verified Roman's model and were able to predict the leaching behavior for a relatively large scale column test on coarse ore.
