The gold should slip down into the smelting vessel. After this occurs, you can cool and remove the gold from the smelting vessel and also remove the slag as well. It''s common at this point to refine the gold through a separate refinement process to ensure a high level of purity.
I am currently separating and extracting gold from margin ore dump (Mod) using the following processes: leaching, carbon in pulp, elution (zadra process) and electro winning. My final product (sludge gold) is contaminated with excessive copper. What method should I apply in order to make sure t
#0183;#32;You must heat the gold containing copper ore until it becomes molten. With the gold being a heavy metal than copper, the gold will settle to the bottom and then you can pour off the copper. 0 0

#0183;#32;You can remove the most common metals found in gold ore (copper, zinc and lead) using elements that bond with oxygen at lower temperatures than gold. This oxidation process will make copper oxide, zinc oxide and lead oxide all of which are less dense than pure gold and will float to the top of your crucible allowing the slag to be sloughed off.
This Guide is best suited for gold plated or pure gold object. THIS SHOULD ALSO NEVER BE ATTEMPTED INDOORS. *Cupellation is a refining process in metallurgy, where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like lead, copper, zinc, arsenic, antimony or bismuth, present in the ore.

I separated gold from gold+copper mixture and finally I am having a solution of copper nitrate and now I wish to separate the copper from the solution. I don''t know the separation process for separating copper from copper nitrate. Please guide me in this aspect. Prabar Natarajan Student India
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

It isn''t, gold(Au), silver(Ag) and copper(Cu) are all separate elements. But if you''re talking about when they add copper or silver to gold, it''s to harden it, so you can''t bend it in your hands.
You may precipitate the copper out of the copper sulphate solution by inserting a metal that is more reactive than copper, such as magnesium or iron. Copper metal will precipitate, but the magnesium/iron will dissolve and you will ultimately be left with a solution of magnesium or
How I can separate gold from copper? Quora
#0183;#32;cement all the values using copper. either a copper buss bar or clean copper pipe. put the copper in the solution for 23 days. after this, any gold, silver, palladium or platinum will be in a black powder on the bottom of the container. siphon the solution from this powder and test with stannous chloride to make sure all PM''s have been removed, and then you can selectively dissolve the metals
All Gold apart from 24c pure Gold contains Copper as an addition. If so it is going to be cant do it at home. You need to use 50% Nitric acid will dissolve the Copper but not the Gold. Then filter off the Copper Nitrate and you are left with a sludge of Gold.
