Abstract

The monomineral extraction of molybdenite and stibnite is tested and analyzed using non-frothing flotation, adsorption, IR spectroscopy, multiple frustrated total internal reflection and potentiometric measurements. The ionized sulfhydryl collectors tested at concentrations of 10-4 mole/l in a pH range of 2–12 include butyl xanthate, diisobutyl dithiophosphate, diisobutyl dithiophosphinate and sodium diethyldithiocarbamate. The test nonionized collectors are diesel fuel and O-isopropylNmethyl thionocarbamate. Molybdenite shows higher floatability than stibnite in application of individual collectors in a pH range of 4.5–8.0. Stibnite is better floatable with diisobutyl dithiophosphate, while molybdenite flotation is more active with diesel fuel. The general critical concentration found for the modifiers H2O2 and Na2S2O3 is \(4.4\cdot 10^{-3}\) mole/l—the flotation activity of molybdenite and stibnite is minimal at this concentration of the agents. Different sorption forms of the ionized sulfhydryl collectors are proved by the multiple frustrated total internal reflection infrared spectroscopy. Anisotropism of mineral electrodes Sb2S3 and MoS2 made along and across the crystal lattice cleavage is experimentally confirmed. The ratio rating of grains of low-oxidizable sulfides, broken along the cleavage or in other direction relative to the cleavage, can modify the process properties of molybdenite and stibnite.
