Flotation test sulfur result graphic using fuel oil. Fig. 12 shows the flotation test result sulfur graphic using different conditions. Accordingly, sulfur content reduction amounts of S1, S2, and S3 experiments performed by using different reagent options; when the sulfur ratios of C1 concent content obtained between 0–30 s are examined ...
The raw ore flotation test showed that IPETC displayed superior flotation performance to the elemental sulfur compared with sodium ethyl xanthate () and ammonium dibutyl dithiophosphate (ADDTP ...
1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached air …
As an important indicator of flotation performance, froth texture is believed to be related to operational condition in sulphur flotation process. A novel fault detection method based on froth texture unit distribution (TUD) is proposed to recognize the fault condition of sulphur flotation in real time. The froth texture unit number is calculated based on texture spectrum, and the probability ...
Selective Flotation of Elemental Sulfur from Pressure Acid Leaching Residue of Zinc Sulfide Guiqing Liu 1,2, Kaixi Jiang 1, Bangsheng Zhang 2, ... At the beginning of the test, the residue and ...
An efficient flotation process was developed to selectively recover elemental sulfur from a high-sulfur pressure acid leaching residue of zinc sulfide concentrate. The process mineralogy analysis showed that the sulfur content reached 46.21%, and 81.97% of the sulfur existed as elemental sulfur which was the major mineral in the residue and primarily existed as pellet aggregate and biconical ...
The company carried out a test campaign with its own Hybrid Flotation cell in the laboratory. An iron ore concentrate containing 67 % Fe and 1.3 % S was used as the feed material. The target of the test campaign was to reduce the sulfur content to below 0.4 % in the final concentrate. The required iron recovery was at least 95 %.

However, Pilot test of neutralization slag by hydrothermal sulfide flotation indicated that hydrothermal technology is expected to realize industrial application in the future [137]. Therefore, some challenges and questions that should be solved. The environment of high temperature and high pressure is …
Flotation Test of High Sulfur Copper Ore in the Northwest in Yunnan. Article Preview. Abstract: The experimental ore belongs to a kind of typical high sulfur ore,which makes it to be a refractory ore.The copper in the ore has a relative high grade which comprehensively reaches 3.78%,with the chalcopyrite occurs the main form.After a serious of ...
The sulfur flotation concentrate can be treated. with an innovative process [7,8] to purify the sulfur to +99.9% and simultaneously remove. selenium and tellurium. The residue chalcopyrite of the ...
ton of sulfur (as hydrogen sulfide) gave satisfactory results at the test plant of the Magma Copper Company on malachite. Sodium sulfide has been tested at the concentrators of a number of the larger copper companies, having been added to the flotation machines or to conditioning tanks before flotation as tests showed that better sulfidlzing of the
Additions of three arious dosages of sodium silicate to the sulfur flotation werev tested. Pine oil of 20 g/t and kerosene of 20 g/t were also added in each test. Pulp pH was maintained at about 6. The flotation results are shown in Table II. Table II. The effect of sodium silicate on sulfur flotation. Test No. Sodium silicate, g/t Grade, %
