Select the appropriate reagent for concentrating operation. #1 Cyanide method: It is used when suppressing copper and floating lead. The mixed-use of sodium cyanide and zinc sulfate has a good effect on the inhibition of secondary copper minerals, but it has a dissolving effect on gold and silver, so attention should be paid to the dosage.

From a reagent viewpoint, charged water soluble collectors such as xanthates, dithiophosphates, some thiophosphate analogs including phosphinates, and some recent adaptations of nitrogen based collectors starting from either urea and/or amines, are the most successful reagents used, e. g. Klimpel (1994). Pyrite as it occurs in sulfide mineral systems requires a collector to float.

A high pH, the correct reagent concentration and activation time and a short time delay between reagent additions is favourable for separation of sphalerite from pyrite. Sufficient oxidation potential is also needed (through O(2) conditioning) to maintain effective galvanic interactions between sphalerite and pyrite.
