  202415 · Oxidizing Roast; Stibnite the Antimony Mineral The leading antimony mineral is stibnite. In smelting stibnite ore two processes are available, precipitation and roasting-reduction. The former is suited, only for high-grade ores. As low-grade ores are more common than high-grade, roasting-reduction is of greater importance than …

  Leaching kinetics of antimony-bearing complex sulfides ore …

  201791 · China is the largest producer of antimony in the world [2]. The most important antimony resource exploited in China is the antimony ore containing stibnite (Sb2S3). Traditionally, extraction of antimony from stibnite involves a two-step pyrometallur- gical process including roasting and carbothermal reduction [3,4].

  Selective alkaline leaching of antimony from Low-grade …

  To eliminate the adverse effect of antimony on extracting of gold in matte smelting process from Sb-bearing refractory gold ores, the sodium sulfide leaching method was proposed to selectively remove antimony in advance. On the basis of the analysis and characterization of raw materials (XRD, SEM-EDS, mineralogical phase analysis, etc.), it can be detected …

  Ferric chloride leaching of antimony from stibnite

  201961 · This practice indicates that Sb 2 O 3 would cohere on gas ducts, thus leading to a low melting point and strong bondability. Molten salt smelting was adapted to the smelting of stibnite in molten sodium salt, however, the regeneration of molten salt is difficult. (Padilla et al., 2014b) investigated the sulfur-fixing roasting of Sb 2 S 3 using ...

  Mechanism of stibnite volatilization at high temperature

  2017827 · Volatilization roasting−reduction smelting is mainly used to produce antimony from sulfide ores and concentrates. In this process, antimony sulphide is volatilized and then oxidized into antimony trioxide (Sb2O3) in a rotary kiln of a shaft furnace. Finally, Sb2O3 is reduced to antimony by carbon in a reverberatory furnace.

  Cleaning of high antimony smelting slag from an oxygen …

  201981 · AbstractCleaning of high antimony smelting slag from an oxygen-enriched bottom-blown was tested by direct reduction in a laboratory-scale electric furnace. The effects of added CaO, mass ratio of coal (experimental) to coal (theoretical) (ω) and the slag type on the reduction procedure were considered. The contents of Sb and Au were …
