Abstract
The report presents the results of a series of bench-scale experiments using the so-called 'cementation' reaction (i.e. electrochemical reduction by contact with a metal of higher oxidation potential) for the precipitation of copper and the reduction of hexavalent chromium in industrial waste streams such as brass mill and metal finishing discharges. Reluctants studied included soft iron shot, particulate iron, and silicon alloys in granular form. The bulk of the work was done using the iron shot as a reductant. Studies were carried out by both a batch process and a continuous process (black-mix reactor). Results were evaluated in terms of percent reduction, dissolution of excess iron and change in pH vs time. (Modified author abstract)
