How to Recover Copper from Solution

25.03.2017  An electrolytic method for the recovery of pure copper from sulphate solutions is far preferable and will produce cheap copper. In all cases a low current density is required. Hard-lead anodes or composite anodes of hard lead and coke of uniform thickness will be used.

Recovery of Copper by Solution Mining Methods - Arizona

The copper-bearing solutions were recovered from sumps located on the 1,000-foot level of the underground mine workings and pumped to the surface, where the copper was initially recovered by precipitation onto tin cans or scrap iron and later by solvent extraction-electrowinning (SX-EW) methods (Ahlness and Pojar, 1983).

Which metal is used to recover copper from a solution of ...

Originally Answered: Which metal is used to recover copper from a solution of copper sulphate? To remove copper from copper sulfate, all you need to do is add a more reactive metal, sodium for example. As sodium is more reactive than copper, it removes the sulfate group from copper and bonds with it, leaving pure copper precipitate. 3.8K views

inorganic chemistry - When recovering Copper from Copper ...

23.05.2017  About a week ago in my Middle School Science Class, we used an aluminum washer and some copper chloride, which we had gotten from creating circuit boards, in a closed system to recover the copper (if it was possible). We resulted in getting some copper flakes, but as a consequence the copper was replaced by aluminum in the chloride solution.

Copper Precipitation Methods

26.03.2017  The copper can be precipitated from this solution by means of scrap iron, the cement copper going directly to the blast furnaces or converters. The use of sponge iron is more attractive than the use of scrap iron, however. It can be made from calcines which contain about 50 per cent. iron. This makes the process independent of the scrap-iron market. But the use of

09.04.2013  The optimal result for simulated copper solution was 99.9% copper recovery efficiency in current density 0.585 A/dm 2 and no iron ion. Due to high concentration of iron and chloride ions in real industrial wastewater, the copper recovery efficiency was down to 60%. Although, the copper recovery efficiency was not high as simulated copper solution, high
