The ore grade and depth influence on copper energy input

Aug 21, 2009 el teniente porphyry copper deposit, the world’s greatest intrusion-related cu–mo ore body, is hosted within basaltic–andesitic volcanic and gabbroic rocks mafic complex. this ore body is strongly affected by multiple events of alteration/mineralization with pervasive potassic and chloritic alteration and coetaneous with associated copper mineralization.

Sep 19, 2009 the host rocks, however, have varying amount of magnetite and carbonates in subordinate quantity. the main copper ore is chalcopyrite. pyrrhotite is the most abundant sulphide mineral followed by chalcopyrite and pyrite . magnetite and carbonate occur in subordinate amount. the mineralization occurs in the form of disseminations, stringers and mining.

Iron oxide copper-gold iocg deposits hitzman et al., 1992 are a diverse family of mineral deposits characterised by the following features: 1 cu with or without au, as economic metals, 2 hydrothermal ore styles and strong structural controls, 3 abundant magnetite and/or hematite, 4 fe oxides with fe/ti greater than those in most igneous rocks, and 5 no clear spatial associations mining.

By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. the entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. this allows immense cost savings for transport, since the waste rock is disposed of on-site.May 28, 2021 established in 2004, red rock resources red rock is a natural resource exploration and development company. the company manages a diverse portfolio of mining, oil and gas investments around the world. this includes the migori gold project in kenya and the luanshimba copper-cobalt project in the drc.
