    Copper anodes from the converter process are dissolved electrolytically using an acid copper sulphate solution as an electrolyte The products of this operation are pure copper cathodes and an anode slime which may contain gold and small quantities of the platinum group metals The cells are constructed of rubber-lined concrete...

  • Demo of sulfides from gold cleanup floating on water

    Jan 02, 2014· I was doing a gold cleanup of some gold concentrates from crushed iron ore When I noticed the sulfides floating in cool patterns on the surface tension of the water...

  • How I can separate gold from copper?

    Jul 05, 2019· My answer is to getting the gold free of copper, and it works for any alloy 1 Raise the surface area/volume Beat it until it is as thin as possible, or crush it and do your best to make dust/tiny fragments 2 Put the whole of the sample into a....

  • Copper extraction

    Copper extraction refers to the methods used to obtain copper from its orThe conversion of copper consists of a series of physical and electrochemical process Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors...

  • Acid Leaching

    If the crushed ore contains excess fines it may be advantageous to add a coarse fraction of ore or waste material to avoid the necessity of removing fin STORAGE AND FEEDING THE ORE Steel ore bins of field welded tank type are used since they can be secured in most areas and installed at a lower cost than other forms...

  • Copper Ore

    The copper ore production process operation as defined in Section 31 is simulated for a period of one year with various failure mod The time evolution of the cumulative cost curves and copper output for 100 Monte Carlo (MC) simulations are shown in Figure 5 for easier visualisation More MC simulations can be done while characterising the system...

  • Copper Smelting Process

    We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process Mining for Copper Bearing Ore There are two categories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment...

  • Heap leaching

    Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the ....

  • METALLURGY OF COPPER

    Blocks of blister copper are used as anodes and thin sheets of pure copper act as cathod The cathode plates are coated with graphite in order to remove depositing copper The electrolyte is copper sulphate (CuSO4) mixed with a little amount of H2SO4 to increase the electrical conductivity...

  • copper extraction and purification

    Purification of copper When copper is made from sulphide ores by the first method above, it is impure The blister copper is first treated to remove any remaining sulphur (trapped as bubbles of sulphur dioxide in the copper - hence "blister copper") and then cast into anodes for refining using electrolysis Electrolytic refining...

  • Crushing Ore to Recover Gold

    Jun 11, 2012· Crushing a small ore sample to recover the gold buried inside This sample was found in a lode vein in Marion County, Oregon The ore is heavily laden with copper and pyrite along side of quartz...
