Block of the week: copper ore minecraf
This secondary enrichment occurred when pyrite iron sulfide oxidized, dissolved in rainwater, and formed an acidic iron sulfate solution that dissolved the main copper-ore mineral, chalcopyrite copper-iron sulfide. the dissolved copper was redeposited, principally as the mineral chalcocite copper mining.
Chalcopyrite cufes2 is one of the most abundant copper-bearing minerals, which accounts for approximately 70 percent of the world’s known copper reserves. for more than 30 years, a significant number of processes have been developed to leach copper from chalcopyrite concentrates. these processes recover copper via hydrometallurgical leaching of the copper component of chalcopyrite mining.
Jul 09, 2019 1 chalcopyrite cufes2 chalcopyrite including cu 34.57 is the most common copper mineral in china’s copper mines, has good buoyancy. chalcopyrite is not easily oxidized, and it can maintain natural floatability for a long time in neutral and weakly alkaline pulps.
