Low Grade Better Than High Grade Tell That to My

Copper minerals and ores are found in both igneous and sedimentary rocks; mining of copper ores is carried out using one of two methods: underground mining or open pit mining. For commercial exploitation, copper deposits generally need to be more than 0.5% copper, but preferably over 2%. Figure 1- Primary usage for copper and copper alloys, based on results of a survey of the primary

Copper extraction Wikipedia

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Enhanced methods for nickel recovery from low-grade

High-grade nickel ores are almost exhausted, since they are so heavily exploited and less abundant than the low-grade ores. High-grade nickel oxides are produced by fluid-bed roasting and chlorine-hydrogen reduction of nickel matte. High-purity nickel pellets are produced by using vapour processes, an example of this is the carbonyl process: the copper and precious metals remain as a

Copper ores Danafloat

Home|Mining|Copper ores. 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. A typical copper sulphide ore contains various
