A method of electrowinning or electrorefining copper from a copper electrolyte solution which contains chloride ions, the method comprising the steps of: (a) forming a polyacrylamide solution by dissolving polyacrylamide, having a molecular weight range of 5,000 to 20,000,000 Daltons, in an acidic medium and under conditions to form a polyacrylamide block copolymer having …
The invention relates to a process that allows electrolytic copper cathodes to be produced, using the pregnant leach solution (PLS) directly in the electrowinning, avoiding the step of mineral concentration by solvent extraction. Furthermore, this process has a modular structure and the full process can be mobilised depending on the requirements of the process itself.
Abstract Electrolytic copper refining allows one to obtain high-purity copper, so analyzing the main ways impurities transition into electrolysis products is a relevant problem. Solving it makes it possible to control the process when changing the composition of raw materials and, as a result, the content of impurities in the anodes. In this work, on the basis of …
The present invention relates, generally, to a method and apparatus for recovering metal values from a metal-bearing materials, and more specifically, a process for recovering copper and other metals through leaching, electrowinning using the ferrous/ferric anode reaction, and the synergistic addition of ferrous iron to the leach step.

1. A method of electrowinning or electrorefining copper from a copper electrolyte solution which contains chloride ions, the method comprising: forming a polyacrylamide solution by dissolving polyacrylamide, having a molecular weight range of 5,000 to 20,000,000 Daltons, in an acidic medium and under conditions to form a polyacrylamide block copolymer having …
Copper electro-refining (Cu-ER) is the principal method for producing >70% of high or 99.97% pure copper cathodes from 97-99% pure blister/fire refined-scrap copper anodes. While the inert and most of less soluble impurities settle as anode slime/sludge, other soluble impurities, particularly the metalloids (group VA/15 elements or Q: As, Sb and Bi) and some transition …
This paper describes the application of an anode-support system (AS) to the direct electrorefining of chopped copper scrap using the bipolar connection (series system). The authors have determined that it is possible to utilize a specially designed basket made with sheet (cathodic face) and mesh (anodic side) titanium, under the same operating conditions used for …
The present invention relates, generally, to a method and apparatus for electrowinning metals, and more particularly to a method and apparatus for copper electrowinning using the ferrous/ferric anode reaction. In general, the use of a flow-through anode—coupled with an effective electrolyte circulation system—enables the efficient and cost-effective operation of a copper …
