Minerals Free Full-Text Preparation of Antimony Sulfide and
Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony sulfide were analyzed
The flotation of gold bearing ores — A review - ScienceDirect
1994.7.1 Abstract. The practice of the flotation of pure gold and gold-bearing ores such as tellurides, aurostibite, kerogen, pyrite, pyrrhotite, copper-gold ores and mixed sulphides is reviewed. The factors which influence the choice of collectors, pH and Eh, are discussed as well as the application of differential flotation.
The metallurgy of antimony - ScienceDirect
2012.7.17 Antimony has been produced from ores in over 15 countries. As shown in Table 2 (Carlin, 2012), world reserves of antimony are estimated to about 1.8 million metric tonnes.As China, the leading producer, accounts for about 90% of the world's mined production and the vast majority of the reserve base (i.e. reserves consist of
Three Methods To Antimony Ore Beneficiation And Processing
2023.10.27 There are many varieties of antimony ore, including antimonite, antimonite, antimony, antimony ochre, etc. Depending on the properties of the ore, the optional beneficiation processes include manual selection, gravity separation and flotation. The density, color and metallic luster of stibnite are significantly different from those of
Treatment of antimonial gold ores - ScienceDirect
2005.1.1 Gold and antimony are associated in a number of gold ores with resulting complications in the gold extraction process. The principal mineralogical forms, in which gold occurs in these ores are metallic gold, free-milling, or associated with silicate gangue, as metallic gold associated with stibnite [Sb 2 S 3] will be seen from the processes used to
Stibnite - an overview ScienceDirect Topics
Flotation of Gold–Antimony Ores Gold–antimony ores usually contain stibnite (1.5–4.0% Sb), pyrite, arsenopyrite gold (1.5–3.0 g t −1 ) and silver (40–150 g t −1 ). Several plants in the USA (Stibnite, Minnesota and Bradly) and Russia have been in operation for some time.
Treatment of Antimonial Gold Ores - ScienceDirect
2016.1.1 New Plant Design4.1. Low-Grade Antimony Gold Ores. For gold ores, where minor, economically insignificant stibnite occurs, it is difficult to be prescriptive concerning the optimum flow sheet because stibnite is seldom the sole problem mineral, with arsenopyrite and similar minerals nearly always being present.
A Review on Pyrometallurgical Extraction of Antimony from
2022.8.12 Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting. The performance of most of the pyro-processes is very sensitive to concentrate type and grade. Therefore, technology
