Aug 12, 2015· Flotation Depressants Flotation Depressants Post navigation Previous Next Sodium cyanide is occasionally substituted for lime in theFlotation is conducted at high pH levels often times greater than 11 using lime to ensure good depression of sulphide minerals, particularly iron sulphides and copper Other depressants used include cyanide and Nokes reagent (thiophosphorous or thioarsenic compounds)Copper Molybdenum Flotation depressant Barium SulphateJun 01, 2020· This work evaluated the performance of S 2 O 3 2− and the mixture of S 2 O 3 2− and Cu 2+ as a novel copper depressant in the selective flotation of chalcopyrite and molybdenite The depression effect was studied by flotation test, and the depression mechanism was revealed through Zeta potential, contact angle, XPS and Raman measurementA novel copper depressant for selective flotation of

COPPER DEPRESSANTS: CORRELATION BETWEEN STRUCTURE

MoS2 depression followed by copper flotation is practi ced in only two plants (notably at the Kennecott Utah Division), using dextrin Starches, saporin, various organi c dyes and formaldehyde are some o f the effective MoS2 depressants2 Arnong the important, commercially used copper depressants, sodiumJul 01, 2021· Prior flotation tests showed that tiopronin was a prospective copper depressant in CuMo sulfide separation With the purpose of further testing the selectivity ability of tiopronin, artificial mixed minerals were utilized for flotationTiopronin as a novel copper depressant for the selectiveThe copper flotation tailings are the feed to the sphalerite flotation circuit where the zinc minerals are floated as explained in the leadzinc flotation section Sphalerite is first activated with CuSO4 and floated typically at elevated pH for iron sulphide depression Combinations of xanthate with either dithiophosphate and/orCopperZinc ores Danafloat

The recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 05%TCu (open pit mines) and 12%TCu (underground mines) is of
