Process of purification of copper

A process for efficient separation/recovery of copper involving selective extraction of the copper ion with the aid of an organic extractant from an aqueous chloride solution containing copper and one or more concomitant elements, discharged from an extractive metallurgy of non-ferrous metals or the like, and subsequent stripping

    Purification of Copper Electrolyte by Solvent Extraction

    Nov 28, 2010 A couple of refineries have adopted the solvent extraction (SX) process in place of the electrolytic route which is commonly employed for the purification of copper electrolyte with respect to various impurities. The SX process based on TBP (Tri n-Butyl Phosphate) solvent is particularly effective in the separation of arsenic from the electrolyte

    In the process of purification of copper, two electrodes of copper are placed in the solution of copper sulphate. The two electrodes are: impure copper rod and thin copper plate. When these rods are connected to the battery, the electricity passes through the solution and the solution undergoes electrolysis. So, there is a formation of \[C{u^{2

    The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu 2 S+O 2 → 2Cu+SO 2. The sulphur dioxide escapes the copper and this causes bubbles to appear and burst as SO2 leaves. This causes the final product to have a very blistery appearance and hence it is called Blister Copper;
