2021-10-18 Pyrite particles, having framboidal/altered texture, are known to significantly affect pulp chemistry and adversely affect flotation performance. Therefore, the main objectives of this study were to demonstrate influence of pyrite mineralogy on the flotation of copper (sulphidic) ores and develop alternative conditions to improve the performance.

1977-9-1 An electrochemical investigation of pyrite flotation and depression. Int. J. Miner. Process., 4: 227--239. The oxidation of ethyl xanthate on pyrite electrodes, and the influence of the flota- tion depressants hydroxide, cyanide, and sulphide, have been investigated using cyclic voltammetry. A layer of a hydrated iron oxide has been identified ...

2016-11-28 auriferous pyrite flotation is 9-10 because of dolomite existence in this material, as shown in Fig. 3. pH 9 was further used for all flotation tests. As shown in Fig. 3(a), using SIAX alone as collector and Terpenic oil as frothing agent, better auriferous pyrite flotation could be achieved when the SIAX concentration is higher than 40 mg/L.

2019-11-1 In this paper, the flotation separation of pyrite from sub-bituminous and meta-bituminous coals in the presence of slimes was investigated. The sub-bituminous coal and the meta-bituminous coal have significant differences in their surface properties compared with pyrite. The flotation experiments were performed in the presence of potassium amyl ...

2018-12-1 Pyrite flotation conditions include: Aerophine 3418A, 40 mg/dm 3, MIBC, 10 mg/dm 3, collector and frother condition time for 3 min, and flotation time of 5 min. After the tests, it was shown that the concentration of starch does not have much effect on the recovery of pyrite, and the effect of depressant increases or decreases with pH change [22] .

The results showed that flotation kinetics of pyrite is second-order. After obtaining optimal condition for flotation and kinetic studies, the effects of type and dosage of different organic depressants including starch, dextrin, guargum, carboxymethyl cellulose, EDTA and DETA at three concentrations (50, 100, 150 ppm) at neutral pH were ...

In this paper, the influence of the oxidation state of pyrite and arsenopyrite on the flotation of an auriferous sulphide ore was investigated by different techniques, including electrode, pulp potentials, DRIFT spectroscopy and microflotation tests. In addition, the gold and sulphide recoveries were also investigate, in a laboratory-scale cell, as a function of pulp potential and reagent ...

2021-11-1 Numerous works have been performed to investigate the phenomena happening on the surface of pyrite during flotation. However, most relevant works were undertaken in extremely acid solution (pH of 0 or 1) or in the moderate alkaline solutions (pH of 8 to 10) [18] , [19] , [20] , with few covering the common range of pH in a systemic manner.
