Copper-sulphide Ore Processing

Copper extraction - Wikipedia

The processing techniques depend on the nature of the ore. If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate the valuable minerals from the waste (gangue) minerals. It is then concentrated using mineral flotation.

Copper Mining and Processing: Processing of Copper Ores ...

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.

Copper Mining and Extraction Sulfide Ores

Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are: See for further information on the leaching process.

Sulphide Leaching - Mineral Processing & Metallurgy

Copper sulphate can be used to separate Copper from Nickel in a sulphide ore or Copper from Fe in Cu -Fe sulphide ore. CuSO 4 solution can also be used for removing Pb, Zn, and Fe from copper sulphide ores. In presence of oxidizing agents: Ferric ion: Ferric sulphate or chloride react with metal sulphides liberating elemental sulphur, e.g.

Copper Sulfide Flotation - Mineral Processing & Metallurgy

Summary of the copper sulphide ore recovery process. It is essential to have flexibility in any mill circuit, but particularly in large-tonnage operations such as this. Changing ore, changing market conditions and many other factors make this flexibility absolutely necessary.

Mining and Extraction: Oxide Ores - processes for ...

The process used to treat sulfide copper ores begins at the mine site, where the copper-bearing minerals are physically separated from the rest of the rock. The flow diagram below shows how the percentage of copper increases as the ore is refined, first physically by froth flotation, then chemically by smelting and finally electrolytic refining.

Sulfide Ore Processing « TCB Metals and Refining

Processing Sulfide Ores Historically, miners have shipped their sulfide concentrates to overseas smelters that have little to no regulations or emissions controls. However, with the implementation of the Mercury Export Ban of 2008 and the high costs of installing equipment to prepare sulfide ores for cyanide leaching, many companies are ...

Frontier Mine A copper sulphide concentrate ... - ERG Africa

The open pit mine’s processing facilities treat over 10Mt of copper sulphide ore annually, producing circa 350kt of concentrate. In 2018, it produced 102 058t copper contained in concentrate. In 2018, we continued investment in our Frontier Mine to extend its life.

Sulfide Ores - an overview | ScienceDirect Topics

Mined sulfide ores contain pentlandite, pyrrhotite, chalcopyrite and gangue rock. A high-grade nickel concentrate is produced from these ores by the following minerals-processing techniques: (a) crushing and grinding the ores to liberate the nickel- and cobalt-bearing minerals from the …

Copper Ore Types: Sulfides vs. Oxides | INN

May 28, 2019 · Both ore types can be economically mined, though they are processed in different ways. Copper sulfide ores are typically the most profitable types of copper ores …

Flotation of Nickel-Copper Sulphide Ore: Optimisation of ...

different levels was investigated. Therefore, the main objective of the study was to optimize the process parameters for the flotation of base metals from a nickel-copper sulphide ore. 2. Materials and Methods 2. 1. Materials The nickel-copper sulphide ore used in this study was supplied by Trojan Nickel Mine located in Bindura, Zimbabwe.

What is the best method for sulfide copper leaching?

A low grade sulphide ore leaching could be contemplated using an oxidative / bacterial heap leach. Another option is to concentrate the sulphides using flotation, then atmospheric or pressure...

(PDF) A Review of the Flotation of Copper Minerals

These oxidised copper minerals are found in weathered regions of most copper sulphide ore bodies The overlaying oxidic ore is usually stockpiled after it is removed from the sulphide lode and left...

Copper Sulphide Ore Pyro-metallurgy Process - Buy Copper ...

Inside the furnace, copper sulphide ore (raw ore or concentrate after beneficiation), react s with the oxygen, and become copper matte (Cu 2 S& FeS, precious metal) which settle down to smelter hearth bottom, slag (non-metal, Ca, Mg and Si) which is on the top, and SO 2 in the off-gas.

Copper sulfide - Wikipedia

Copper sulfides describe a family of stone compounds and minerals with the formula Cu x S y.Both minerals and synthetic materials comprise these compounds. Some copper sulfides are economically important ores.. Prominent copper sulfide minerals include Cu 2 S and CuS ().In the mining industry, the minerals bornite or chalcopyrite, which consist of mixed copper-iron sulfides, are often ...
