·01 Copper sulfur ore sorting technology Copper sulfur ore contains copper sulfide minerals and iron sulfide ores which can generally be divided into two types 1 Dense massive copper bearing pyrite The gangue mineral content is small and the method of preferential flotation of copper sulfide ore is often used The tailings after copper flotation are
·The main copper ore body in general corresponds closely with the extend of the earliest alteration event and the potassic mineral assemblage zone characterized by the presence of secondary K feldspar and biotite accompanied by abundant anhydrite and magnetite within volcanic host rocks Biotite isotopic composition from Darreh Zar porphyry
·The ore deposition process at the Ak Sug deposit was accompanied by a change in the phase and chemical composition of the ore forming fluid The early high temperature fluid of the porphyry copper stage was heterogeneous and composed of an aqueous vapor and chloride brine with high metal contents which is evident from daughter ore mineral
·The composition of copper ore samples was analyzed with the use of fluorescence and chemical methods Table 1 shows the content of the main valuable component—copper—as well as metals with the highest content that affect the leaching process From fluorescence analysis
To comprehensively reuse copper ore tailings the recovery of γ Fe 2 O 3 from magnetic roasted slag after sulfur release from copper ore tailings followed by magnetic separation is performed
·Magmatic fertility to generate porphyry and high sulfidation copper ore deposits generally develops not at the scale of individual igneous complexes but rather at the scale of petrochemical provinces spanning hundreds of kilometres of arc length and containing many igneous complexes The extent and duration of copper metallogenic provinces and epochs are
·Besides the ore minerals also other sulfides oxides carbonates silicates and alteration minerals were quantified Figure 1 shows an example of a full pattern Rietveld quantification of a copper ore and Figure 2 summarizes the mineralogical composition of the 100 measured copper ore samples
2 ·Copper processing is a complicated process that begins with mining of the ore less than 1% copper and ends with sheets of % pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy
·However recent studies on the timing of sulfide saturation have shown that most magmas from porphyry copper deposits became sulfide saturated before the ore formation—including the two mega deposits of El Teniente and Rio Blanco porphyry copper deposits—which suggests that sulfide saturation is a second order control for ore formation
The method used to extract copper from its ores depends on the nature of the ore Sulfide ores such as chalcopyrite CuFeS 2 are converted to copper by a different method from silicate carbonate or sulfate ores Chalcopyrite also known as copper pyrites and similar sulfide ores are the commonest ores of copper
·The choice of copper ore processing technology depends on its composition the sulfide oxide carbonate and copper silicate content Leaders in copper ore processing include Chile Peru the United States Australia China Russia Mexico Kazakhstan Zambia and Congo Chile accounted for almost a third of global copper produc tion in
The copper ores are mostly found in the north of India The extraction of copper also involves many steps The ore used for extraction is copper pyrites which is crushed concentrated and then heated in the presence of air During heating the moisture gets expelled and the copper pyrites gets converted to ferrous sulfide and cuprous sulfide

·Fig 1 XRD profile of copper rich gold ore sample Fig 2 Sulphides of copper and other metals identified by SEM analysis of flotation concentrate produced from ore for mineralogical analysis Leaching tests Leaching tests were conducted in baffled glass reactors 1000 mL in nominal capacity into which leach solutions 480 mL and the ore
·extracting copper from it a spell was cast on the ore by a nickel It was only red nickel pyrites NiAs for the veins of ore worked in seams also incorporated copper and iron sulphides as well as arsenides In England the term cupronickel was used at the start of the 20th century for an alloy of 80% Cu and 20% Ni

TY JOUR T1 Distinctive composition of copper ore forming arcmagmas AU Loucks Robert PY 2014 Y1 2014 N2 Magmatic fertility to generate porphyry and high sulfidation copper ore deposits generally develops not at the scale of individual igneous complexes but rather at the scale of petrochemical provinces spanning hundreds of kilometres of arc length and
·Mining Mining of copper ores is usually done in large open pit mines which are open holes in the ground that are dug deeper gradually Explosives are used to blast the rock and the resulting boulders are transported for crushing into smaller pieces for processing 2 Extraction There are two main purification processes for the two common
·Entrainment of any suspended sulfide particles is favored by forceful ascent of magmas in the tectonic setting where porphyry copper deposits are found Loucks 2021 and the H 2 O rich and oxidized composition of such fertile magmas promotes subsequent sulfide decomposition and transfer of sulfur and metals to ore forming fluid in the upper
·Abstract The review of copper ore processing flow charts in application at ore mills in Russia and abroad is presented The scope of the analysis embraced the reagent regimes and flotation performance Brief information about collecting agents frothers and depressants is given The influence of actuation medium in flotation of copper nickel ore is studied in terms of
·In 1982 Quintana produced Mst of ore recovering Mlbs of copper 2301 oz of gold and the composition of Copper Flat carbonates does not appear to be completely dependent on context or elemental inheritance On a molar basis Mg and Fe are more abundant than Mn in secondary mafic silicates but Mn is greater than Mg in more than
