amount of copper in sulphide ore

PDF LEACHING OF A ROASTED COPPER SULFIDE ORE Jhunalyn Parantar ...

In roasting copper was mainly formed to soluble sulfate by The copper sulfide ore was roasted at 900 degrees C water or dilute acid after roasting. Mostly this for one hour. The total copper % CuO and CuSO4 method is applied to pretreatment of copper was determined through the analysis of copper and concentrate with high percentage of sulfur.

Copper Ore Types: Sulfides vs. Oxides An Investor& 39;s Perspective INN

Copper sulfide ores are typically ... the project also features two grinding circuits where high-grade copper concentrate is extracted from sulfide ore. The deposit hosts large amounts of ...

Heap Leaching Oxide and Sulfide Copper Ores

Any additional copper that may have been leached from these ores would only have been possible at the expense of large amounts of acid per pound of copper recovered. The precipitation of copper on iron and the recycle of the spent solutions caused a buildup of iron to 10 grams per liter in the leach liquors.

The Complete Collection of Copper Beneficiation Reagents - Fote ...

Copper and sulfur in copper ore have strong collection properties which is also conducive to improving the recovery of associated gold in copper sulphide ores. The flotation effect of refractory copper-sulfur ore containing secondary copper minerals is better than that with butyl xanthate but its selectivity is worse.

Copper Sulfide - an overview ScienceDirect Topics

The leaching of copper sulfide and copper oxide ores entails partial dissolution to cupric sulfate with sulfuric acid and iron sulfate. The presence of pyrites in many ore deposits and its reaction with water and oxygen to form iron sulfate and sulfuric acid creates an important source of acid.

extraction of metal from sulphide ore metal take copper with reaction ...

Ores are the sediments and the rock that contain some concentrated metal that can profitably extracted from them. To extract the metal of low Reactivity series we use the following method: took example of copper sulphide Cu2S Roasting : It is the process in which the sulphides ores are heated in presence of large amount of air.

How is copper extracted from its sulphide ore? Explain the various ...

Then electrolytic refining of copper is carried out to remove the rest of the impurities present in the ore. The impure copper is made anode and strip of pure copper are made hode. On passing the current as shown in the diagram the pure copper from the anode dissolves into an electrolyte. An equivalent amount of copper is deposited on the ...

Copper Extraction from Sulfide Ores - Latest Contents

This process is used for the extraction of copper from low grade sulfide ore. In this process the crushed and ground ore in bulk about 100000 tons is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides.

Mining Industry Copper Sulfide Ore and Flotation Process - JXSC

1 Types of copper sulfide ore 1 Single copper mineral Its ore characteristic is relatively simple and the only useful component that can be recycled is copper. The gangue minerals are mainly quartz carbonate and sili e. 2 Copper-sulfur ore Called copper-bearing pyrite. In addition to copper minerals iron sulfide can be recovered and ...
