3) Temperature and pH. Cobalt is a metal that can be a bit picky when it comes to conditions in which it will electrowin. It doesn't like being too hot, or too cold, and it definitely doesn't like being at the wrong pH. Cobalt prefers a temperature range of 40-600C and a pH of below 2 or greater than 4. These three parameters are not full ...

Jan 01, 1999· Copper blanks have been used in the preparation of thin copper after a 24 hour plating cycle in order to generate starter sheets. Similarly nickel is often plated for typically 24 hours or less, to facilitate the preparation of starter sheets in electrorefining operations in Hybinette cells which employ sulphide anodes placed in protective ...
An electrowinning cell of novel design has been described by Treasure (2000).Named as EMEW R cell, it consists of a cylindrical in place of planar electrodes. The outer tube is the cathode and the inner one is anode. The diameters of the electrode tubes are sized according to the particular application to minimize cell voltage for a given solution chemistry.
to use EMEW (electrowin) technology involving a new design for an electrolytic cell through which the material would be passed for treatment, having first been leached. The EMEW technology, according to Mr Nutter, would provide the opportunity to put in a low operating cost plant to treat materials and produce metals in site.
