Copper is extracted from the ore chalcopyrite CuFeS How manykilograms of a 0 862% chalcopyrite ore will be necessary to produce1 00 kg of pure copper? The percentage of copper in chalcopyriteneeds to be known to work this problem

Chalcocite is an important copper mineral ore It has been mined for centuries and is one of the most profitable copper ores The reasons for this is its high copper content (67% atomic ratio and nearly 80% by weight) and the ease at which copper can be separated from sulfur

Bacterial consortium for copper extraction from sulphide

However at the end of the test in Figure 2 the consortium achieved a good extraction of copper being in second place There is a difficulty in the extraction of copper from different bacterial consortium due to the large amount of chalcopyrite present in the mineral studied (70% total Cu)

The biological leach achieved 65% copper extraction in 160 days This level of copper extraction is significantly higher than any previously reported results (typically /10% copper extraction) and represents a significant advance in the bacterial leaching of chalcopyrite ore

Subsequently a mechanism for copper dissolution was proposed by employing relevant experiments including the chemical leaching of chalcopyrite by sulphuric acid and ferric sulphate solutions bioleaching of chalcopyrite in the presence of added ferric ions and cell attachment analysis by scanning electron microscopy

Bornite This specimen contains primarily bornite and chalcopyrite with apatite The first two minerals are primary sources of copper ore Bornite is an important copper ore mineral found in many different types of copper deposit It is also known as peacock ore because of its iridescent purple-blue-green tarnish Fresh bornite however is

May 05 2018The addition of NaCl in the ammonium persulfate-APS (as an oxidant) leaching was investigated APS has some advantages compared with conventional oxidants and its standard redox potential (E) is 2 0 V Effect of six parameters such as NaCl concentration APS concentration temperature time liquid–solid ration (L/S) and stirring speed on the leaching behavior was studied

The pyrite in which small amounts of gold occurs is of crystalline variety (primary pyrite) The characteristics of primary pyrite are a absence of porosity an extreme brittleness a resistance to oxidation and the existence of gold possessing a weak susceptibility to magnetism (due to a fine coating of a iron compound)

A Novel Process for the Treatment of Copper Concentrates

GALVANOXTM –A Novel Process for Copper Concentrates GALVANOX takes advantage of the galvanic effect between chalcopyrite and pyrite Chalcopyrite is a semiconductor and therefore corrodes electrochemically in oxidizing solutions In ferric sulphate media the overall leaching reaction is as follows CuFeS 2 + 2 Fe 2 (SO 4) 3 → CuSO 4 + 5 FeSO

In many societies copper was the first known metal to be widely worked and for over six thousand years copper mining has remained a CHALCOPYRITE The World's Most Important Ore of Copper for Chalcopyrite is a brassy yellow mineral with the chemical composition CuFeS2 or copper iron sulfide

The method used to extract copper from its ores depends on the nature of the ore Sulphide ores such as chalcopyrite are converted to copper by a different method from silicate carbonate or sulphate ores Getting copper from chalcopyrite CuFeS 2 Chalcopyrite (also known as copper pyrites) and similar sulphide ores are the commonest ores of

Chalcopyrite is an Ore it must be smelted in an Ore Smelter to extract Bar of Copper or Bar of Cast Iron with 8% and 4% respectively chance (% showed with all mining skills) otherwise it smelts into Slag Ore is a type of Stone so it can also be used as pavement and to build with Chalcopyrite

However at the end of the test in Figure 2 the consortium achieved a good extraction of copper being in second place There is a difficulty in the extraction of copper from different bacterial consortium due to the large amount of chalcopyrite present in the mineral studied (70% total Cu)

Increasing temperature pH glycine concentration and DO concentration all increase the rate and extent of copper extraction The extraction of copper from "as-received" chalcopyrite flotation concentrate at a particle size of -45 m in solutions containing 0 4 M

Chalcopyrite has a golden yellow color which often resembles Gold However its physical properties such as streak and tenacity are very different from Gold and can easily distinguish it Chalcopyrite is a beautiful mineral with good crystals being fairly common

Solvent extraction in hydrometallurgical processing of Polish copper concentrates 209 The Polish copper ores exhibit very favourable mineralogical composition in terms of leachability Chalcocite (Cu2S) and bornite (Cu5FeS4) easily leachable minerals predominate in the Polish ores while content of chalcopyrite (CuFeS2) and covellite

Copper is much rarer but fortunately can be found in high-grade ores (ones containing a high percentage of copper) in particular places Because copper is a valuable metal it is also worth extracting it from low-grade ores as well Ores are commonly oxides for example bauxite (Al 2 O 3) haematite (Fe 2 O 3) rutile (TiO 2) or sulfides
