Ore microscopy (mineragraphy or mineralography) is the study of polished surfaces of ores or of ore minerals by means of a polarizing, reflected-light microscope and the interpretation of the mineral associations and microtextures so observed. The earliest reference to polished-ore techniques is that of Berzelius of Sweden who, about 1806 ...Web

Separation flotation method can also achieve good results for refractory oxidized copper ore. It is to crush the mineral to a certain particle size, mix 0.1% ~ 1.0% salt and 0.5% ~ 2.0% pulverized coal, and heat it to about 900 ℃ in oxygen isolation. The copper in the ore will precipitate on the carbon particle surface in metal state.Web
