Properties of Copper Ores—Page 3 2. Note the physical appearance of each sample, paying close attention to color, clarity, and any other distinguishing characteristics.
Properties of a substance that can be observed without attempting to change the substance into another substance are physical properties. If the investigation of a property involves an attempt to change the substance into another substance, that property is a chemical property.
Copper ores The main copper sulphide minerals are chalcopyrite (CuFeS2) chalcocite (Cu2S), covellite (CuS), bornite (Cu5FeS4), tetrahedrite ((Cu,Fe)12Sb4S13) and enargite (Cu3AsS4). The largest source of copper is from porphyry ore deposits in which one or a combination of …
Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society.
What is Chalcopyrite? Chalcopyrite is a brass-yellow mineral with a chemical composition of CuFeS 2.It occurs in most sulfide mineral deposits throughout the world and has been the most important ore of copper for thousands of years.. The surface of chalcopyrite loses its metallic luster and brass-yellow color upon weathering.
