Process 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.
The influence of iron ore characteristics on FeO formation during sintering was examined mainly in terms of chemical composition and the melting characteristics of iron ores. Statistical regression and Xray diffraction were used to further explain the specific effect of iron ore characteristics on FeO formation.
Ore Deposits Formed by Sedimentation. The process of sedimentation results in the formation of some important mineral deposits viz., iron, manganese, copper, phosphate, coal, oil shale, carbonates, cement rock, diatomaceous earths, bentonite, fuller's earth magnesite, sulfur and uraniumvanadium deposits.
