The quantity of antimony in an ore can be determined by an oxidation‑reduction titration with an oxidizing agent. The ore is dissolved in hot, concentrated acid and passed over a reducing agent so that all of the antimony is in the form of Sb3+(aq).
Feb 08, 2016 At the same time, research is still ongoing to optimize the primary production of antimony from stibnite ore and to reduce the amount of (toxic) waste streams [7, 16, 25, 26]. Yang et al. [ 25 ], for example, developed a low-temperature sulfur-fixing smelting process, using a NaOH–Na 2 CO 3 flux with ZnO to fix the sulfur as ZnS.
Sep 07, 2017 Antimony oxide ore beneficiation has become one of the world’s largest mineral processing conundrums. In recent years, many experimental studies dealing with antimony oxide ore have been carried out, resulting in new technical achievements. Much attention has been paid to improving the mineral processing technology of antimony oxide based on such experiments. This.
Feb 08, 2016 Alkaline sulfide leaching was used (Na 2 S NaOH) to extract antimony from the ore, which was then electrodeposited as antimony metal. Using this approach, the antimony content in the concentrate was reduced from 1.7 to less than 0.1 Sb, which is desirable for copper.
Dec 02, 2012 The quantity of antimony in an ore can be determined by an oxidation-reduction titration with an oxidizing agent. The ore is dissolved in hot, concentrated acid and passed over a reducing agent so that all the antimony is in the form Sb3 (aq). The Sb3 (aq) is completely oxidized by an aqueous solution of BrO3– (aq).
Apr 11, 2021 The purpose that we reduce the grade from 40 to 16 is to expand the utilization of antimony ore. Further , it is necessary to enhance the cooperation with surrounding countries and those with rich antimony resources, strengthen bilateral and multilateral cooperation mechanisms, and expand the import market of antimony concentrate.
Jan 14, 2021 First, because antimony ore is often formed as coarse single crystals or massive aggregates, high-grade massive antimony concentrate suitable for antimony metallurgical technology can be obtained through manual selection, which can reduce the production cost and energy consumption of beneficiation.
African antimony ore dressing type. antimony ore dressing Antimony ore handpicked method based on differences of antimony minerals and gangue in color luster shape and this dressing method is relatively primitive laborintensive but can produce large size high quality antimony concentrate ore can reduce ore dressing costs and energy consumption.

Antimony ore proportion is heavy than matrix , normally gravity separation is efficient , its efficiency , economic , environment protection and concentrate the lower grade ore , after gravity use flotation for extraction .,It is a high technological enterprise that integrated research , manufacture, sales and service .
We can provide Antimony Ore under the following specifications, and are able to have 200 MT per month , and 500MT per month, within 45 - 90 days respectively, from the execution of a Sales and Purchase Agreement. Product Antimony Ore Quality 45 -65 Shape Lumps Size 6-10 Inch State Non-Concentrate Color Metallic Grey Moisture 0.11.
Feb 06, 2017 Removal of arsenic, antimony and bismuth from copper may take place in the smelting operations by scorification, volatilization, or, under special treatment, by processes of concentration. Owing to the great variety of materials that are treated in economical metallurgy, it is rarely possible to obtain exact weights from any particular operation.
Quality and Price stipulation of Antimony Material Purchase Antimony Mineral sand (lump ore ,powder ore ,floating selected sand mine) Quality Standard Pb Sb ≤0.23 As Sb ≤ 0.8 lump ore particle size exceed 30mm ,less than 150mm. Lump Standard Sb ≥30 or 5 ≥Sb 30 ,and S Sb≥26 ,Powder ore standard Sb≥25 ,.
The extraction of Antimony from its ore At this moment, it will be necessary to reduce the power of the burners in order to avoid oxidation and sublimation of the sulphur. Remember Liquation is a kind of distilation per descensum and not a sublimation or a calcination .
Slag, usually running under 1 antimony, is desired because it tends to reduce volatilization losses. Sb 2 S 3 + 9 O 2 2 Sb 2 O 3 + 6 SO 2 (7).

May 16, 2016 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 of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of quartz but contains, in addition, a small amount.
Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace. Smelting of roasted (calcine feed) or unroasted (green feed) ore concentrate produces matte, a molten mixture of copper sulfide (Cu2S), iron sulfide.
According to the antimony production companies, 1 ton of antimony production results in the generation of approximately 4.5–5 tons of waste slag. Although part of the slag is frequently reused in the furnaces to reduce volatilization losses (Anderson, 2012), a larger part of it becomes waste. This antimony waste.
