Antimony-bearing ores in the Fairbanks district Alaska are found principally in two areas the extremities of which are at points 10 miles west and 23 miles northeast of Fairbanks; and one of two minor areas lies along this same trend 30 miles farther to the northeast. These areas are probably only local manifestations of mineralization that affected a much broader area and formed antimony.
Antimony Ore. Antimony is a lustrous tin-white metal. Although it is usually described as a metal it possesses mixed metallic and nonmetallic characteristics and is more properly described as a semimetal or metalloid. The antimony ore found in our mine is Stibnite which is a sulfide bearing ore and is concentrated using a froth flotation.
A wet chemical process was developed for the separation of gold from gold-bearing antimony sulphide ores. The ore sample was taken from the mine Urquidi from Oruro in Bolivia. It contained roughly 33 Sb in the form of antimonite. 24 Si in the form of quartz small quantities of Pb Fe Cu and Ni as well as 63 gt gold 60 of it as visible gold.
Several aspects of the process technology for treatment of antimony-bearing ores have been studied. The feasibility of separating contaminant antimony minerals as early as the mine planning stage is discussed. The possibility of separating contaminant antimony minerals depends on the mineralogy of the ores and the flotation properties of the.

Antimony and Gold from Gold-Bearing Antimony Ores 109 2.2 Preparation of Metallic Sb The main reaction for the production of metallic Sb is the interaction of Sb2S3 with iron.
Jan 01 1997 Epithermal Mercury-Antimony and Gold-Bearing Vein Lodes of Southwestern Alaska Authors. Isotopic data from sulfide and alteration minerals of the Hg-Sb lodes indicate multiple sources for the ore fluids; most fluids appear to have originattd in local sedimentary rocks. Hydrothermal fluids with isotopically heavy oxygen but isotopically.
Prices for ores ranged from 1 to 2.10 per unit of antimony. At first only ores carrying 50 per cent or more antimony were in demand but before the close of the year 20 per cent ores were being shipped from Nevada.
The extraction of antimony from ores depends on the quality of the ore and composition of the ore.
United States Antimony Corporation USAC NYSE uamy is a rapidly growing natural resource company that is increasing its raw material supply of antimony from properties in Mexico and third parties around the world. USAC has produced various antimony products since 1969 and is a fully integrated mining transportation milling smelting and selling company.

Dec 04 2000 The smelting and refining of these ores yield antimony‐bearing materials that may be treated to recover elemental antimony. Recycling of antimony provides a large proportion of the domestic supply of antimony. Secondary antimony is obtained from the treatment of antimony‐bearing lead and tin scrap such as battery plates.
In fact a higher reactivity with acid is observed for freshly precipitated Sb2S3 than cristalline Sb2S3 present in antimony bearing ores. If for the precipitation sulfuric acid is used a solution of Na2SO4 is obtained.
Dec 27 2013 Techniques for the processing of antimony‐bearing ores encompass a wide range of techniques from traditional hand sorting which is dependent on plentiful and cheap labour to technologically advanced capital‐intensive mineral processing. The main antimony products in international trade are stibnite and subordinate stibnite‐berthierite.
Portable-XRF analysis of artifacts from Resuloğlu and mineralogical analysis of an antimony-bearing ore fragment present evidence of use of antimony at the region during the Early Bronze Age. This period is followed by disappearance of antimony in material record until the Iron Age while textual records weakly refer to its circulation within.
Antimony is a silvery-white metal that is found in the earths crust. Antimony ores are mined and then mixed with other metals to form antimony alloys or combined with oxygen to form antimony oxide. Little antimony is currently mined in the United States. It is brought into this country from other countries for processing. However there are companies in the United States that produce antimony.

Epithermal mineral deposits and occurrences of southwestern Alaska consist of Hg-Sb and gold- and sulfide-bearing vein lodes. Numerous Hg-Sb lodes are located throughout a region measuring several tens of thousands of square kilometers in and surrounding the Kuskokwim River basin in southwestern Alaska. The Hg-Sb lodes are hosted in sedimentary rocks of the Cretaceous Kuskokwim Group the.
Antimony is found in trace amounts in silver copper and lead ores and it is usually economically possible as well as environmentally desirable to extract the antimony from these ores when they are smelted.
Feb 08 2016 Depending on the concentrations of gold and antimony different categories of Au-Sb-containing sulfide ores can be distinguished 1 ores in which gold is the main valuable component and antimony is a harmful impurity 2 gold-bearing ores in which the amount of antimony is considerable and for which it is economically viable to recover.
Antimony is sometimes found in pure form. It is also obtained from the mineral stibnite antimony sulfide and commonly is a by-product of lead-zinc-silver mining. Other antimony-bearing minerals include sibiconite tetrahedrite and ullmannite. It is mined in China Bolivia South Africa and Mexico.
