Improves flotation kinetics and intermediate resistance. DEHSCOFIX®FH15. DEHSCOFIX® FH15 is a selective foamer for precious metal and base metal flotation. It is used as an alternative to methyl isobutyl carbinol (MIBC) and low molecular weight alcohol based foams. Typical applications are gold, lead-zinc, and copper mining.
Namibia Custom Smelters (NCS) process a range of copper concentrates in their three furnaces, namely; top submerged lance, copper converter and reverberatory furnaces, in order to produce mattes and fayalitic slags. The copper content of the slags range between 0.8 to 5 wt. % and this is considered too high for disposal to the environment.
