2015-11-1  1. Introduction. The selective separation of copper–molybdenum sulfide minerals by flotation mostly relies on the use of various depressants. Sodium hydrosulfide, sodium sulfide, cyanide and Noke’s reagent (thiophosphorus or thioarsenic compounds) are routinely used as the selective depressants of chalcopyrite (Bulatovic, 2007, Pearse, 2005, Prasad, 1992, Yin et al., 2010), the main copper

The Effect of Seaweed Glue in the Separation of Copper

Flotation separation of chalcopyrite from molybdenite was studied using seaweed glue (SEG) as a depressant. Flotation process and mechanism were examined by response surface methodology, flotation tests, adsorption tests, zeta potential measurements and fourier transform infrared (FT-IR) spectra. Response surface methodology with a Box–Behnken design suggested the optimal reagent
