 — 1. Background. Antimony is a silvery, white, brittle, crystalline solid that exhibits poor conductivity of electricity and heat. It has an atomic number of 51, an atomic weight of 122 and a density of 6.697 kg/m 3 at 26 °C. Antimony metal, also known as 'regulus', melts at 630 °C and boils at 1380 °C.Antimony and the natural sulfide of …

 — 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 …

 — 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. Zhang et al. studied the recovery of antimony and bismuth from pressure-leached flue dust created during the smelting of copper. They used a three-step process consisting of a kerosene …

Gold containing antimony concentrate in Shandong, China was selected as the research object in this study. The main chemical composition of the ore sample is shownin Table 1. The leaching rate of gold will be weak due to the influence of antimony if direct leaching gold is carried out by cyanide. As is

 — Antimony ore concentrate (principally trisulfide, also called stibnite in less amounts, as well as oxides such as valentinite, senarmontite, and cervantite) was examined in one inhalation study, as was antimony trichloride . Exposed animals were mice, rats, and voles. Exposure doses varied widely and exposure duration ranged from single gift ...

These results were compared with other published results, including an animal inhalation study with Sb2O3 in which lung tumors were also induced and higher concentrations of arsenic were found in tissues from rats than from male rats. This study was initiated because of a suspected increase in incidence of lung cancer in antimony smelter …

 — The powder XRD was used to identify the main phases in the antimony-bearing gold concentrate and leachate. The mineralogical analysis of Au and Sb were …

A new process for one-step extraction of antimony in low temperature from stibnite concentrate by reductive sulfur-fixation smelting in sodium molten salt, using iron oxide as sulfur-fixing agent, was presented. The influences of molten salt addition and composition, ferric oxide dosage, smelting temperature and duration on extraction efficiency of …

 — Antimony leaching from tetrahedrite-bearing ores was typically carried out by using Na2S-NaOH solutions. In the current paper, the detail mechanism of antimony leaching from tetrahedrite-rich concentrate via K2S and BaS lixiviants was investigated for the first time. Sample was characterized in terms of chemical, mineralogical, and …
