    This is related as: 1) iron sulphide mineral levels are usually much higher than copper concentration, 2) sulphide flotation collectors can float iron sulphides well also, 3) liberation can be an issue making copper and iron separation difficult, andCollectable Copper Ores and Minerals This is a selection of the most commonly collected copper ores Also included are a few other interesting ores of metals often alloyed with copper such as zinc, lead and bismuth Illustrations are beingCopper OresThis copper–molybdenum (Cu–Mo) sulfide ore is generally mined from various locations in the mining site; thus, the mineral composition, oxidation degree, mineral particle size, and grade vary Therefore, in the mining operation, it is common to blend the ores mined from various spots and then process them using flotationMinerals | Special Issue : Recent Advances in Copper Ore

  • A Brief Introduction to Copper Oxide Ores | Fote Machinery

    A Brief Introduction to Copper Oxide Ores As the world's demand for copper continues to grow, the resources of primary copper sulfide ore that are easy to mine and beneficiate have gradually decreased It's urgent to explore and utilize copper oxide ore resources to mitigate the shortage of copper resources The more you know about the copperI Haapala, H Papunen, in Mineral Deposits of Finland, 2015 Discovery of the Outokumpu (Keretti) Copper Deposit The discovery of the Outokumpu copper ore in North Karelia was an epochmaking achievement in the history of the Finnish mining industry The story of the discovery has been described in numerous articles in Finland and abroadCopper Ore an overview | ScienceDirect TopicsIn most cases, the thinlayer process was used where crushed ores (80% −05 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 L·hour −1 ·m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides Of note, 80%–85% copper extraction was commonly achievedCopper Ore an overview | ScienceDirect Topics
