Antimony Recovery from End-of-Life Products and

08/02/2016 This approach reduces SO 2 emissions (98.61 % sulfur-fixing) and results in an antimony recovery rate of 97.07 % in the form of antimony metal. Ye et al. [ 26 ] investigated a similar system, using a eutectic Na 2 CO 3 –NaCl molten salt and ZnO as a sulfur-fixing agent.

Studies on the Recovery of Secondary Antimony Compounds

Recovery of antimony is highlighted because it is a critical element and the known natural resources are rapidly becoming depleted. The MOVs contain a significant amount of antimony but have minimal waste volumes. Characterization of the MOV determined the microstructure of the MOV contained the three major phases (1) the zinc rich phase dominated by ZnO grains, (2) the antimony rich phase

Process flow-sheet for gold and antimony recovery

01/10/2000 After leaching, antimony has been recovered by electrodeposition, in order to increase the economical convenience of the subsequent gold extraction. Antimony recovery has been about 70% Sb for suitable conditions of leaching and electrowinning. Metallic antimony with high purity was obtained.

Treatment of Antimonial Gold Ores ScienceDirect

01/01/2016 For a period from 2008 to 2010 when Hillgrove was operated by Straits Resources, a mixed stibnite/iron sulfide concentrate was subjected to alkaline sulfide leaching with antimony recovered by electrowinning to produce antimony chip, which was then smelted to produce antimony ingots. The operation experienced technical and financial difficulties, however, and was put on care and maintenance in 2010. No gold recovery

Antimony Recovery from End-of-Life Products and

For low-grade ores (5–25 % Sb), oxide volatilization is used. The ores are roasted at 1000 C, and the volatile Sb2O3 is recovered. Intermediate grade ores (25–40 % Sb), and Sbrich residues, slags, mattes, and flue dusts are smelted in a blast furnace at 1300–1400 C which produces antimony

Antimony Speciation in Alkaline Sulfide Solutions:

26/01/2002 Antimony is subject to a lower drinking water standard than arsenic, its notorious group 15 cohort in the periodic table. Both elements often co-vary in nature and are fairly soluble under reducing, alkaline conditions. Of the two, much less is known about the environmental chemistry of Sb. Measurements of Sb solubility in sulfidic solutions equilibrated with stibnite (Sb2S3) and orthorhombic sulfur

Extracting antimony from high arsenic and gold

01/06/2019 The antimony content in crude antimony was 94.31%. Although this process with short flow could eliminate the low-concentration SO 2 pollution, the antimony recovery rate and the antimony content in crude antimony were low. In the treatment of high arsenic and gold-containing stibnite concentrate, the problem of arsenic alkali residue is still

A fundamental study of the alkaline sulfide leaching of gold

Since the sulfur can be easily separated from the gangue minerals, this provides a simple way of producing a concentrated gold sample prior to leaching. It has also shown that gold can be selectively recovered from complex alkaline sulfide solutions containing a mixture of metals such as arsenic, tin, mercury and antimony. These studies showed that almost 100% of the gold

antimony is recovered from scrap, which serves as a secondary source of the metal. Most of the primary antimony used in the United States ·is obtained from stibnite ores and concentrates imported from Latin America. Numerous deposits of antimony are reported in Alaska, but th is area suffers from high costs of transportation to markets. The price antimony

Antimony separation process Sunshine Mining

By comparison, sulfur addition (and therefore polysulfide addition) did at initial, lower levels increase antimony recovery. However, at higher levels, sulfur addition actually decreased antimony recovery. Nonetheless, at high levels of sulfur (polysulfide) addition a high percent recovery can be attained by a larger initial addition of caustic to the leach liquor.

The amount of sulfur dioxide released depends on the characteristics of the ore—complex ores may contain lead, zinc, nickel, and other metals— and on whether facilities are in place for captur-ing and converting the sulfur dioxide. SO. 2. emissions may range from less than 4 kilo-grams per metric ton (kg/t) of copper to 2,000 kg/t of copper. Particulate emissions can range

In this research, the bacterial removal of arsenic and antimony from mixture of sulfide and carbonate zinc and lead ore, with local mesophilic bacteria was studied. The purpose of this study was to indicate the optimum pulp density, Fe(II) concentration and initial pH to achieve the highest dissolution of arsenic and antimony. The results showed that the arsenic recovery through 23 days process (51 %) was much more than the leaching without bacteria (12 %). Also, the maximum antimony
