PETKOM-30 REAGENT A NEW COLLECTOR FOR COPPER MINERALS

This paper presents the results obtained with flotation reagents in comparison to conventional reagents, on flotation tests at laboratory level with minerals at the Plants. At the tests, collectors from those Plants were used and these new reagents, with a modification of the particle size distri- bution, Collector dosage and ph of the pulp. These new reagents achieve better metallurgical pa- rameters regarding the standard collector, increasing the law of copper in the concentrate and recovery. Furthermore this reagent has a positive effect, since it is based on a mixture of salts 2- mercaptobenzotiazol, has a reduced toxicity in compared to conventional reagents that causes a better impact on the environment. 1.
