Smelting Stibnite For Antimony Operation Samoa

One-Step Extraction of Antimony in Low Temperature

 · stibnite = 40%, where W represents weight, smelting at 850 C (1123 K) for 60 min. Under the Under the optimum conditions, the direct recovery rate of antimony can reach 91.48%, and crude antimony

Separation of Antimony from a Stibnite Concentrate

 · The extraction of antimony from stibnite was studied by smelting it in the presence of zinc oxide, sodium carbonate, and a small amount of sodium hydroxide.

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 precipitation. In the roasting process the aim may be to leave the oxidized antimony in the ore, or it may be to .

Reductive Sulfur-Fixation Smelting of Stibnite

 · A new process to extracted antimony directly from stibnite concentrate by reductive sulfur-fixation smelting in sodium molten salt has been presented.
