Make Gold From Copper, Silver amp;Amp; Plant Extracts. Making GOLD from Copper, Silver amp; Plant Extracts. 2003. A. This letter depends on what he really meant. Is he asking how to make 10 or 14 or 18 K gold from 24K gold, or is he asking how to extract pure gold out of an alloy, or is it a dream of making 10K gold into 24K gold by alchemy.
#0183;#32;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 copper(I) ion and, consequently, a lower energy consumption in leaching. Copper(II) ions and oxygen are used as oxidants.
Gold Recovery: Wait dont throw those old electronics in the garbage, theres gold in them there things. How about putting it in your pockets instead of someone elses pocket? Laptops, phones, cameras, and the like are filled with gold plated circuit boards even
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...
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. Melt the Gold sludge in a furnace and you can cast it into Gold metal ingots.
I have been given a project on optimization of copper concentrate grade so as to improve copper and gold recovery. I need help on the main factors which I have to consider in my project. The targeted copper concentrate grade at the plant is 18 20%Cu, but currently the target is not achieved. The p

Extracting Gold Extracting gold is a term related to gold. Learn about extracting gold at HowStuffWorks.
Gold is formed independently from rocks so unlike iron or copper there is no ''ore'' to extract it from. In general gold is acquired by finding nuggets in rocks.
Copper sulphides Concentrates, from the flotation process of copper primary ore; contain, commonly, small amounts of precious metals, such as gold and silver. During the smelting process of those concentrate all gold and silver are practically in the blister copper, which is cast into anodes.

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 dangerou

#0183;#32;Gold is leached at potentials gt;600 mV vs. Ag/AgCl and recovered from the solution by precipitating it on activated carbon or copper concentrate (Hyv#228;rinen et al. 2004, Haavanlammi et al., 2007b
#0183;#32;A. Dissolve all with aqua regia, then ppt out the copper with NaCl, then filter out the copper chloride and then ppt out the gold as pure with sodium metabisulfite mixed with water. Filter the gold fines and smelt. You could try dissolution in Nitric acid and that leaves the residue as gold.
