The complex As-Au-Sb ore is also an important antimony resource that is predominantly mined in Hunan and other places in China. It is essential to develop an economical and environmentally friendly process for the extraction of antimony from this ore. Antimony production involves hydrometallurgy and pyrometallurgy, the latter being …
In this paper, a clean process for extracting antimony from antimonial refractory gold ores is proposed. Antimony is dissolved into the solution with sodium sulfide as leaching agents. And then pressure oxidation technology is applied to prepare sodium pyroantimonate from sodium thioantimonite solution.
A process which depends on the use of excess NaCl and lime has been described for the extraction of gold from a concentrate by volatilization in a roaster. To avoid loss of gold, the amount of salt added must be held at such a figure that this volatilization does not occur.
The clean production process for extracting antimony from refractory gold ore involves sodium sulfide leaching, pressure oxidation, concentration, and …
As it can be seen from Table 5 and 22% of antimony remains in the final tailings of the selective flotation process. Also, the amount of antimony in this sample was too low to produce a stibnite concentrate and thus further test work to produce a stibnite concentrate was not guaranteed.
Antimony ore samples (mean assay 187 per cent antimony) from Endeavour Inlet, Marlborough Sounds New Zealand, were tested for upgrading by flotation to a saleable product (60 per cent antimony).The effects of activating agents, collectors, frothers, pH, conditioning time, and particle size on the recovery and grade of a stibnite flotation …
Later innovations include the MacArthur-Forrest Process and borax flux extraction. However, one of the most interesting methods is froth flotation. Froth flotation works by exploiting the hydrophobic properties of gold molecules. First, ore is ground into an extremely fine powder.
Rougher flotation is the first step of flotation after the gold–antimony ore is ground, mixed with water and classified. ... Diagram of gold–antimony flotation process. Various methods, including model-based, knowledge-based and data-driven methods, are used in condition recognition. ... In the trend extraction process, the original sliding ...
Keywords: flotation, process optimization, Taguchi orthogonal array, ANOVA. 1. Introduction Froth flotation is widely used for separating base metal sulphide minerals in complex ores. One of the major challenges faced by the flotation of these ores is the ever varying grade and mineralogy as the ore is exploited (Kabuda et. al., 2011).
In this study, on the basis of the occurrences analysis of gold and antimony in Sb-bearing refractory gold ore, the process parameters for extracting antimony by alkaline sodium sulfide are investigated, as well as the mechanism of the NaOH and inhibitor to restrain the gold associated leaching caused by polysulfides and thiosulfates.
How Antimony is Processed by Flotation. The problem discussed in this antimony process study is limited to a concentrator capable of beneficiating 150 tons per day of antimony ore. The antimony in this study occurs as the mineral stibnite (Sb2S3) in association with small amounts …
The effects of sodium sulfide and sodium hydroxide concentration, temperature, leaching time and liquid–solid ratio on the extraction rate of antimony and gold were discussed. Furthermore, the response surface method was applied to distinguish the interaction influence of process parameters on the antimony and gold extraction rate.
The flotation behavior, smelting process, various properties of jamesonite (Pb 4 FeSb 6 S 14) and application of its extraction products were introduced.Jamesonite, as a sulfide mineral with complex composition and structure, is mainly distributed in China.
At present, antimony resources mainly exist in the form of antimony sulfide ore, and the enrichment of the ore is mainly carried out by flotation [2], but a large amount of antimony tailings is ...
Turkey. For this purpose, by revealing the characterisation of the ore, flotation experiments were conducted to determine the conditions to obtain the highest Sb and lowest As contents in the flotation process. Antimony ore used in this study was taken from a region called Turhal located in the central
To provide a theoretical basis for a suitable process to extract gold from refractory gold concentrates, process mineralogy on the acid leaching residue of gold calcine was studied by chemical composition, X-ray diffraction, scanning electron microscopy-energy spectrum, and mineral dissociation analysis.
Processing of this ore has resulted in higher dissolved Sb in mine waters (0.1–1 mg/L), even after water treatment that removes most dissolved As (to 0.01 mg/L) …
The flotation process was developed on a commercial scale early in the 20th century to remove very fine mineral particles that formerly had gone to waste in gravity concentration plants. Flotation has now become the most widely used process for extracting many minerals from their ores.
Antimonite ore is processed by hand-picking–flotation or heavy medium separation–flotation to pick out lump ore, rich lump ore, and concentrate that will go into the smelting process. Antimony smelting is done through the pyrometallurgical process or the hydrometallurgical process, but mostly the pyrometallurgical process.
For fine-grained oxidized ore or refractory oxidized ore, the ore is first reduced to metallic antimony, and then processed using conventional flotation methods. This process requires adding a chlorinating agent and heating in the presence of a solid reducing agent, so that the antimony in the ore is precipitated in the form of chloride …
