Petkom-30 reagent a new collector for copper minerals

Abstract

This paper presents the results obtained with flotation reagents in comparison to conventional reagents, on flotation test´s at laboratory level with minerals at the Plants. At the test´s, collectors from those Plants were used and these new reagents, with a modification of the particle size distribution, Collector dosage and ph of the pulp. These new reagents achieve better metallurgical parameters 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 2mercaptobenzotiazol, has a reduced toxicity in compared to conventional reagents that causes a better impact on the environment.

Preventing decomposition of 2-mercaptobenzothiazole during gas chromatography analysis using programmable temperature vaporization injection

“…9 MBT has been extensively employed in 1148 ĐORĐIEVSKI et al chemical industry before it was tried as a flotation collector; 10 it has been used for flotation of copper, lead and zinc minerals. [11][12][13][14] Fig. 1.…”
