Copper Ore Mining Process

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated.

Copper Smelting And Refining Process Pan Pacific Copper

The refined blister copper is poured into casting molds lined up side by side on the revolving circular table of a casting wheel and cast into anode plates for electrolytic refining. The anode plates are approximately 1m x 1m x 0.05m in size, and weigh 380 kg per plate.

Innovations Introduction To Copper Mining Amp Extraction

Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the worlds largest ...

Copper Mining Electrolysis

The blister copper is already virtually pure in excess of 99 copper. But for todays market, this is not really pure enough It is purified further using electrolysis. This is known as electrolytic refining.. The blister copper is cast into large slabs which will be used as the anodes in the electrolysis apparatus see page 4.The electrolytic refining of copper produces the high quality ...

Copper Purification Process Electrolytic Copper Refining

Dec 29, 2017 Copper Electrolytic Refining Process In the electrolytic refining of copper, a thin sheet of high-purity Cu serves as the cathode. The blister copper plates are taken and used as anodes in an electrolyte bath of copper sulfate, CuSO4, and sulfuric acid H2SO4.

Copper Processing Roasting Smelting And Converting

Copper processing - Copper processing - Roasting, smelting, and converting Once a concentrate has been produced containing copper and other metals of value such as gold and silver, the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or ...

Liberating Copper And Nickel A True Story

The copper matte is mixed with reagents in a converter to rid of the remaining sulfides and oxides to produce blister copper containing 97-98 copper. The blister copper is casted into anodes for electrolytic refining where the impure copper is electroplated into pure copper cathode.
