Direct flotation tests had been conducted to extract the metallic values as much as possible by adding traditional depressants and collectors, such as carboxylmethyl cellulose, starch, sodium silicate, butyl xanthate, (BX), butyl ammonium dithophosphate (BA) and etc., the relatively satisfied recoveries of Cu, Ni, Pt and Pd in the concentrate from bench flotation tests were obtained, however, more than 30% of .
Chemistry of historical sulfide collectors 1882 Xanthate was first made by Zeise 1924 Xanthate first used in flotation 1928 Dithiophosphate first patented for flotation 1954 Thionocarbamate first patented for flotation Collector developments historically focused around thiolbased chemistry Tecflote™: a novel family of sulfide ore collectors
mitigation of environmental hazards of sulfide mineral flotation with an insight into froth stability and . flotation performance. by . muhammad badar hayat . a dissertation . presented to the faculty of the graduate school of the . missouri university of science and technology .
Carboxymethyl cellulose, CMC, is widely used in mineral processing as a flotation depressant, mainly for the depression of carbonate and talcaceous gangue in the flotation of CuNi sulfide and PGM ores.
· Sulphide materials have reported % silver recovery by rougherscavenger flotation and the high silver extraction of % when leached in a bottleroll with cyanide solution. · Transition materials achieved % recovery of silver by flotation and the high .
This combination of flotation and smelting effectively removes most of the deleterious impurities, and thus produces a nickelcobalt matte suitable for leaching and eventual Cyanex 272 separation of nickel and cobalt. Historically of course almost all nickel sulphide ores have been treated in this way; however, not all sulphide ores
Mar 07, 2017· Flotation of sulfide liquid droplets by surface attachment to gas bubbles has been suggested as a mechanism to overcome this problem and allow introduction of Ni into the atmosphere during eruption of the SLIP lavas.
triggers sulfide saturation and fractionation of metals from the melt due to the lower solubility of sulfide, (Jenner et al., 2010). One might speculate whether these fractionation signatures are dominated by crystal settling, or might be explained by flotation mechanisms, if sulfide saturation were
Iron sulfide (pyrite, pyrrhotite, marcasite) depressant used in the flotation separation of base metal sulphides. Also used as an alternative partial cyanide replacement to depress iron and zinc sulfides in Pb / Zn flotation. UNIMAX ® SD210. Iron sulfide (pyrite, pyrrhotite, marcasite) depressant used in the flotation separation of base metal ...
disseminated CuNi ores bearing high serpentine contents. This is the case for the copper and nickel sulphides from the Yunnan Mine, China. Previous batch flotation tests of this ore resulted in satisfactory recoveries of % Cu, % Ni, and % Pt+Pd, and concentrate grades of % Cu, % Ni, and g/t Pt+Pd. However, the MgO ...
Sep 30, 2015· Balmoral Resources Ltd. today announced the results of initial metallurgical testing conducted on drill core collected from the Company's wholly owned H3 Ni .
The recovery of copper by sulphidisation and flotation from a mixed ore has been studied in detail in this thesis. Particular focus was given to the effect of pulp chemistry on the sulphidisation mechanism and subsequent flotation response of oxidised sulphide minerals, both .
Factors in sulphide fines flotation exhibit In contrast increased to the angularity above possibuity. when broken certaIn down ores tocan The problem of the flotation of sulphide fines results colloidal size range because of the dispersal of fibrous from a number of contributory factors that are not clay minerals.
The mineral sample is a flotation process tailing, which consisted essentially of silica, iron and magnesium oxides with % of sulphur. The sample, which bears % of nickel, is composed by near 9% of sulphides, such as pyrrhotite (Fe (1x) S), pentlandite (Fe,Ni) 9. S. 8), violarite ((Fe,Ni) 3. S. 4
Mineralization at the Frankfield project contains arsenopyrite and pyrite as the major sulphide minerals. Bulk flotation of all sulphides results in extremely high gold recovery. However, the gold is almost entirely associated with the arsenopyrite fraction of the ore and is refractory in .
NICU SULPHIDES IDENTIFIED AT PLUMRIDGE NICKEL PROJECT HIGHLIGHTS: Aircore drilling has identified clusters of mafic/ultramafic intrusions with cumulate textures in favourable geological settings Ni and Cu sulphides (pentlandite and chalcopyrite) confirmed through petrographic analysis
Apr 25, 2010· Froth Flotation of Ultramafic Nickel Ore No Pretreatment ... Because of decreasing sulphide ore sources and the cost of treating laterites, increasing attention is directed to the third source ...
Feb 07, 2019· Flotation. The test works of flotation were completed by SGS del Peru. Half drilledcore samples were collected to produce threemaster composite samples: oxides, transition and sulphides.
Fe Ni Cu sulphide or a variable mixture of massive sulphide and an ore characterised by olivine crystals in a continuous matrix of sulphide occupying 30 75% by volume of the rock (called matrix ore). Nickel grades of massive sulphide ore range from 2 to 20 wt% and those of the matrix ore generally fall in the range 1 5 wt% (average wt%).
