Antimony Recovery from End-of-Life Products and Industrial .

The liquation residue 12–30 % Sb can be treated to further improve the recovery of antimony. The iron precipitation method is used to produce antimony metal from concen- trated antimony ores or from the crude antimony issued from the liquation process. In this process, scrap iron is added to molten Sb 2S

Antimony Recovery from End-of-Life Products and Industrial .

Under optimum conditions, the average recovery ratio of antimony reached 92.88 %. Also of interest, are the efforts to recover antimony from a low-grade or complex stibnite ore, as well as from secondary antimony minerals. Yang and Wu 16 developed a new hydrometallurgical process to recover antimony from complex stibnite concentrate.

RECOVERY AND LEACHABILITY OF ANTIMONY FROM MINE- AND SHOOTING .

The study confirmed very low recovery of Sb in soils digested with nitric acid mean 20.9% of total , significantly lower in mine soils 7.6 ±3.4% than in sho- oting range soils 34.2±17.5% .

Domestic mining of antimony is key to U.S. defense and its .

The Stibnite Mining District in Idaho — which incidentally was our stopgap source of antimony during World War II — is home to at least 180 million pounds of antimony.

A selective process for extracting antimony from refractory .

In HCl solution, antimony is dissolved in the form of SbCl 3 by adding oxidizing agents such as Cl 2, FeCl 3, SbCl 5, or H 2 O 2 . Methods for the recovery of antimony from the SbCl 3 leaching solution include hydrolysis, replacement, distillation, and electrowinning. Although the foregoing methods afford high antimony recoveries, they all .

PDF Processing of Antimony at the Sunshine Mine

The Sunshine Mine in KeIlogg, Idaho has recovered antimony from its precious metal tetrahedrite deposits since the 1940& 39;s. A plant was initially constructed as a primary antimony source during.

Mine Water as a Resource: Selective Removal and Recovery of .

Antimony has similarly been removed from alkaline pH > 11 solution prepared from Sb III oxide using an N-methylglucamine NMG -containing porous hollow fibre membrane Saito et al. 2004 . The NMG-fibre membrane was also able to adsorb Sb V , with a maximum recovery of 130 mg Sb/g membrane at pH 3 Kawakita et al. 2006 .
