Copper ores - Danafloat

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 the aforementioned minerals occurs.

The Kingdom of Copper - ArcGIS StoryMaps

2021-3-1  During the Iron Age, people in Faynan primarily mined copper ores from the Dolomite-Limestone-Shale (DLS) geological formation, also known as the Burj Dolomite-Shale (BDS). This geological unit formed during the Cambrian Period (around 550 million years ago), and it was particularly rich in high-quality copper ores.

COPPER Copper production

2008-12-16  Copper production About 80 % of primary copper production comes from low-grade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate

Metal in Egypt - UCL

2014-11-4  Iron production requires temperatures from 1100-1150 ºC (the same as for copper smelting). Iron objects appear very sporadically since Naqada III in Egypt. In Egypt iron comes into common usage only from about 500 BC. The normal way to treat iron is to hammer it. Cast iron was not common.
