A selective process for extracting antimony from refractory gold ore
1. Introduction. Gold is a strategic precious metal that is widely used in ornamentation, currency reserves, and high-tech industries. According to the United States Geological Survey, globally identified gold reserves amount to 89,000 tons, with approximately one-third of that total contained in refractory ores (George, 2009).With …
How Antimony is Processed by Flotation
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 (Sb2S3) in association with small amounts of pyrite, arsenopyrite, galena and lead sulfantimonides. The gangue is composed largely of …
Gold Flotation Process, Equipment
Flotation is a common method for rock gold beneficiation processing, and it is often used to process sulfide gold ore, sulfide gold-containing quartz ore, multi-metal gold-containing sulfide ore, etc. Our gold flotation process can directly discard the tailings and simultaneously the convenience of operation, low operating cost and maximum ...
Flotation of Gold and Gold-Bearing Ores
In Brazil, the application of flotation for gold-bearing ores started in the 1980s (Araujo and Peres, 1995). There are three important Brazilian plants using flotation to process gold ores (Monte et al., 2002). At the São Bento plant, gold and pyrite are floated into a bulk concentrate for further processing by pressure and bacterial leaching ...
