；水玻璃 中图分类号:TD923 文献标志码:A Depressant effect on titanaugite by silicon-containing depressants ZHANG Guo-fan, MA Jun-er, ZHU Yang-ge, FENG Qi-ming, WANG Wei-qing (School... on floatation behavior of fine ilmenite and titanaugite were investigated. The results show that, using the water glass as depressant in the weak acidic system with pH of 5-6, the ilmenite and titanaugite can......
of Technology, Harbin 150001, China) Abstract: In order to characterize the diffusion behavior of Zn as melting point depressant (MPD) and its potential ability on removing oxide film during the brazing......
of the structural stability follows Ni3Si＞Ni5Zr＞Ni2B＞Ni5Hf＞Ni3B＞Ni3B2＞Ni23B6, indicating that the stability of Ni3Si phase using Si as melting-point depressant is stronger than that using B, Zr and Hf as melting......

indicated chemical adsorption between SPH and galena. WEI [6] had synthesized a new organic depressant PPD, and found that PPD depressed galena but activated chalcopyrite, because PPD anion could react... from Fig. 1, the recovery of chalcopyrite is above 85% without SGX depressant in the whole range of pH, and increases slightly in the presence of SGX. The increment of chalcopyrite recovery gets slowly......
DMPS as depressant in the separation of copper-activated marmatite from pyrrhotite in the presence of butyl xanthate. The flotation tests of single mineral showed that DMPS had strong depressing effect... of copper-nickel concentrates. VALDIVIESO et al[6] found that dextrin is a good depressant for pyrite in flotation with xanthate collectors. However, the depressing effect of dextrin does not result......
machine. The pH regulator, depressant and collector were successively added to perform the flotation. At last, the concentrate and tailing were separately dried, weighed and sampled to analyze..., and it is necessary to use a depressant for both calcite and quartz in order to achieve the separation. Fig. 2 Floatability of smithsonite, quartz and calcite as function of GE-609 concentration at pH 10......
(or depressant calcium oxide) and frother in turn, and the conditioning time was 2, 3 and 1 min correspondingly. The flotation time was 3 min. 2.3 Zeta potential measurement The zeta potentials were measured... dosage on floatability of minerals The above flotation test results also show that without depressant, the selective flotation separation of Cu/S can be well realized with collector DLZ under neuter......
siliceous gangue materials [3-5]. Some amines and their salts were also used in the reverse cationic flotation process. The starch and its derivatives are proved to be effective depressant and are commonly... as the collector and a mixture of thioglocollic acid and citric acid as the depressant were proposed. Calcite can be selectively floated away from the sulfide minerals between pH 9 and 11 and dolomite can......
