Nowata’s proprietary technology is licensed within Ghana for the manufacture of antiscalants for the West African mining industry.
These antiscalants are used in CIL and heap leach plants to control scaling. There are high temperature products for use in the elution circuit.
Most scale control is geared to calcium carbonate deposits, increasingly calcium sulphate scale is encountered in some operations where cyanide detoxification is accomplished using sodium metabisulphite. This is controlled by a specially formulated product.
