·Processing of Copper Ore Top Sulfide ore processing Bottom Oxide ore processing The process varies slightly depending on the type of ore that is being mined Sulfide ores are first put through a jaw or gyratory crusher to reduce the rocks to about 7 8 inches This material is then fed to a secondary grinder that further reduces the size
·sulphide/oxide copper gold vein deposit Until June 2009 the sulphide and oxide minerals were respectively recovered by the well established xanthate flotation of sulphides and acid leaching of soluble oxide copper The mixed transitional sulphide/oxide ores were stockpiled in the absence of an economic processing route due to their poor
·The use of thiosulfate to extract gold from refractory ores is promising because of its non toxicity and high selectivity Sulfide minerals pyrite arsenopyrite chalcopyrite major gold carriers in refractory gold ores however hinder gold extraction due to the high consumption of a lixiviant In this study a new method to improve gold extraction from sulfide
Froth flotation is widely used for concentration of base metal sulphide minerals in complex ores One of the major challenges faced by flotation of these ores is the ever varying grade and mineralogy This therefore calls for a continual characterisation and optimisation of flotation parameters such that concentrator performance as a whole is always maintained In this study
·The literature on sulfide minerals is extensive with a number of overview textbooks and monographs Comprehensive reviews can be found in Ribbe Vaughan and Craig and most recently in Vaughan The present article provides a brief overview of the compositions and crystal structures of the major sulfide minerals aspects of their chemistries
Mineral processing In the ore dressing plant the material received from the mine is crushed in several stages and finely ground to a size which ensures that copper minerals are liberated from the waste materials or cases where the next step is leaching most frequently in the case of oxide ores complete liberation of the copper minerals is not always necessary; the ore
Copper processing begins with mining copper ore which contains less than 1% of copper and ends with sheets of % pure copper cathodes Yet the most common source of copper ore is the sulphide ore mineral chalcopyrite which accounts for around 50% of copper production in the world Types of Copper Ore Chalcopyrite
