“…Adsorption studies were performed with the solution depletion/abstraction method, and they stated that the adsorption of xanthates increased and DBDTP decreased for the equimolar mixtures of both the collectors at higher collector concentrations. Alternatively, Corin et al [14] found no evidence of a synergistic effect between diethyl dithiophosphate (DEDTP) and isobutyl xanthate (IBX) for a platinum group ore. The authors reported that the dithiophosphate led to the stabilization of the froth phase and did not contribute to enhancing the hydrophobicity of the mineral surface.…”

The Norwegian mining industry is currently showing increasing interest in the production of metals. Recent research has demonstrated promising results identifying the high potential of the Nussir deposit for the production of copper and other valuable minerals. Mineralogical characterization for Nussir ore samples and their flotation concentrates was performed with optical microscopy and Zeiss automated mineralogy (Mineralogic) where the fine copper sulphide middlings were not completely recovered with a traditional sodium isobutyl xanthate (SIBX) collector. In the current study, dithiophosphate and a mixture of xanthate and dithiophosphate collectors’ interaction on copper and other gangue mineral components of the ore sample were investigated with zeta potential, quantitative adsorption, FTIR studies and Hallimond tube flotation. All the results for single mineral experiments confirmed the feasibility of selective copper sulphide flotation by disecondary butyl dithiophosphate (DBD) as collector. The blend of xanthate and dithiophosphate was chemically adsorbed as individual entities on the surface of the copper minerals via competitive adsorption. A systematic study with DBD and a mixed collector (SIBX and DBD) system was conducted on the coarse grind (−105 µm) of the Nussir ore sample, and the results showed a synergistic interaction between the two reagents. The beneficiated copper concentrate using this mixture of collectors is indeed of improved copper grade and recovery. The highest copper recovery in bench scale flotation was 95.3% with a concentrate grade of 19.4% Cu for DBD collector, whereas mixtures of dithiophosphate and xanthate collectors in the ratio of 3:1 resulted in the highest copper grade (24.7%) and recovery (96.3%).

“…It's not easy to decompose in acidic pulp. Meanwhile, it has week collecting performance to iron sulfide and has strong selectivity [5] . Therefore, aerofloat is a sulfide ore collector which is widely used only after xanthate in practice.…”

“…Many studies into collectors for copper flotation have been carried out [22][23][24][25][26][27][28][29]. Hangone et al (2005), in a study of the effects of thiol collectors: xanthates, dithiophosphates, dithiocarbamates and mixtures of these collectors in the flotation of a copper sulphide ore, showed the di-ethyl-dithiocarbamate was the weakest collector of copper sulphide minerals.…”

“…Corin et al [26] has investigated the roles of two collectors sodium iso-butyl xanthate (SIBX) and sodium di-ethyldithiophosphate (DTP) in the flotation of platinum group mineral (PGM) ore. Results showed that SIBX is a stronger collector and that DTP plays an important role in the recovery of fine particles and an increase in the recovery of PGEs, especially Pd, from the Platreef deposit in South Africa.…”

This paper presents the results of mineralogical and flotation studies on the copper ore from the deposit "North Revir" in the Copper Mine Majdanpek, using different collectors. XRD and ore mineralogical analysis showed that the most common minerals are pyrite and chalcopyrite. Chemical analysis confirm that it is a complex low-grade copper ore with average copper content of 0,273%. The content of precious metals (Au and Ag) was 0.2 g/t and 1.2 g/t, respectively. The main aim of flotation studies have been the effect of collector type on the recovery and concentrate grade in the copper flotation process. Various collectors and combinations of them were used in the rough flotation tests of copper ore. The copper recovery was in the range from 79.43% (test no. 4) to 84.96% (test no. 7). The best flotation results were obtained with mixture collectors of sodium isopropyl xanthate (Z11), dialkyl dithiophosphinates (Aerophine 3404
