ABS ( ammonium bisulfite solution) is used for continuous cyanide removal from industrial waste effluents. Successfully used by Mines as a liquid alternative to SO 2 gas in Inco’s SO 2 /Air process, providing similar performance with the safety of a water-based material.

Thio-Gold ™ (ammonium thiosulfate solution) is an attractive lixiviant for the extraction of gold and silver. Thiosulfate is considered a non-toxic alternative to cyanide and the gold dissolution rates can be faster than conventional cyanidation. In addition, high gold recoveries may be obtained from the thiosulfate leaching of complex and carbonaceous-type ores.

ASD (ammonium sulfide solution) may be used in the copper processing circuit to separate copper from other ores such as molybdenum. ASD may be used by itself or in conjunction with NaHS (sodium hydrosulfide solution) in this process.

In addition, Alkemin, a joint venture of Tessenderlo Kerley, Inc. and Industrial Quimica de Mexico, S.A. de C.V., is manufacturing and marketing Xanthates and Doss. Consult the individual product MSDS for handling and storage information.
