how to extract gold from copper concentrate

for its minerals It is important to note that our goldcoppersilver concentrates are already a highly processed and beneficiated product Whilst the smelters do charge to process our concentrate on average for the contract terms that we have agreed with the overseas smelters we receive 97 of the total value of gold silver and copper

When reviewing Methods of Eliminating Copper from Gold Ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation Preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite azurite and chrysocolla but these acids have but little effect on sulphide copper

To extract precious metals from goldcopper ores and concentrates the presence of copper minerals has detrimental effects on gold extraction unless high

Can someone explain the process of extracting gold once you have obtained a concentrate after putting your alluvial material through a gravity machine We put about 200kg of soil through a gravity machine and ended up with about 2kg of concentrate We then took this to a lab to see what the gold

between the gold and host rock particles in a manner to separate the heavy pieces from the lighter pieces of material Panning is probably the oldest technique used for the recovery of gold Panning is a type of gravity concentration used by prospectors for the recovery of gold from river beds It concentrates the heavy gold

May 08 2008 · I have access to a large amount of Black Sand ore concentrate which has assays showing extremely large concentrations of Gold Platinum and Rhodium But many people say it is worthless because it is impossible to extract the precious metals from the junk especially Iron

How to Extract Gold From Electronics In this Instructable I will show you how to extract gold from computers using products most people have lying around in their homes The way I extract the gold is relatively straightforward and pretty easy but the chemicals used are very danger

Removing the goldbearing rock from the ground is just the first step To isolate pure gold mining companies use a complex extraction process The first step in this process is breaking down large chunks of rock into smaller pieces At a mill large machines known as crushers reduce the ore to pieces no larger than road gravel

So how do you use mercury to extract the gold from goldbearing rock When you mix the finely powdered goldbearing rock with some mercury the gold within the rock dissolves to form whats called a gold amalgam The next step in the process is to separate the gold

Some fairly rich ores require a lot of work to get all the gold and silver out them Historically smelting and roasting of ores have been used to capture the gold from difficult to treat ores Just like those old time miners we dont want to throw any of the silver or gold away as it can be valuable

Mar 19 2010 · At one time mercury WAS used to extract gold from gold ore The rock was crushed and washed over a copper sheet coated with mercury Gold forms an amalgam with mercury and some of the gold

Mar 24 2016 · Extraction of gold from ore revolves around smelting not refining I suggest joining the mining and prospecting forums to learn smelting or leaching techniques Once you have made a good product from ore then you can refine it to a pure metal

HydroCopper technology comprises a chlorideleaching method for copper sulfide concentrates and copper production up to semiproducts As compared with the commonly used sulfate solutions brine solutions offer aggressiveness and stability of the copperI ion and consequently a lower energy consumption in leaching

copper concentrates The essential prerequisite for good gold recovery is a suffi ciently high leaching yield of soluble sulfi des that hinder the dissolution of gold The difference in the gold leaching kinetics in the two concentrates studied is probably due to the presence of coarsegrained gold in the Pyhäsalmi copper concentrate

Gold is a precious conductive and pliable metal that retains a stable value better than many commodities Its chemical properties make it useful for the manufacture of computers parts electronics jewelry and dental work Some people find it profitable to attempt to extract the gold from these scraps then refine and sell it

Copper processing is a complicated process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called cathodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two different processes hydrometallurgy and pyrometallurgy respectively due to the different
