Copper recovery from chloride solutions using liquid

2017-10-31  Copper chloride hydrometallurgy is an active research area due to higher copper leaching kinetics and recovery, what is also combined with high leaching of metal ions such as iron . Therefore, the efficient separation of copper from iron is utmost importance for a copper recovery process.

Solvent extraction of copper from chloride solution I

2013-5-1  Generally there are four processes to recover copper from chloride solution: (1) the precipitation of CuCl at lower temperature and reduction to Cu in the UBC-Cominco and the Cymet processes (Dutrizac, 1992, Peters, 1977), (2) direct electrowinning of Cu from chloride solution (Moyes et al., 2000), (3) the precipitation of Cu 2 O and reduction

Extractants for Copper Recovery from Chloride Solutions

Extraction of copper(II) from concentrated chloride solutions with hydrophobic pyridine derivatives containing electron-withdrawing substituents (ester and alkilamide groups) is discussed. Pyridine type extractants are effective reagents for recovery of copper(II) from chloride weakly acidic solutions. It is possible to select an appropriate structure of reagent to adjust its extraction

Recover Copper and Fully Recycle Spent Copper Chloride

The solution is distilled to first remove water and then to recover the free hydrochloric acid. The distillation continues until the residue is dry. Now the residue is recovered and weighed. For every 1g of copper chloride residue 7 mL of water is added followed by 1 mL of sulfuric acid (98%). The solution is thoroughly mixed.

How to Recover Copper from Solution

2017-3-25  A soluble chloride is added to the sulphate solution of copper and the proper amount of sulphurous acid is added. Moderate heat under pressure—90° C. of heat—precipitated almost all the copper as sub-chloride. The subsequent process of obtaining the copper without volatilization and the recovery of the chlorine offered difficulties.

Removal of chloride ions from a copper leaching solution

The original copper PLS solutions came from the National Copper Corporation (CODELCO), from their hydrometallurgical operations, which contained high concentrations of chloride ions. These solutions contained average concentrations of 22 g/L chloride ions, pH 1.5 1.8 and 20 mg/L uranium. The high chloride contents made the uranium recovery
