2012-10-8 The end of Chinese antimony mining is not nigh. Rather, in the absence of major antimony discoveries in the Middle Kingdom, ever diminishing grades will be the norm. On the homefront, Source A noted antimony ore was increasingly coming from Guangxi and a few other states. Source B also said he expected mining at Xikuangshan would continue ...

2019-12-31 Antimony features highly on the critical minerals lists of many countries including Australia 3, the United States of America 4, Canada 5, Japan 6 and the European Union 7. Critical minerals are those minerals (or elements) considered vital for the well-being of the world's economies, yet whose supply may be at risk of disruption. JORC Ore Reserves

Antimony Potential in Northern Vietnam - Mineral
2019-9-20 The Campha Antimony ore field consists of 40+ larger antimony ore veins, of which about 30 are of economic ore grade. Most of the steeply dipping ore veins and +/-vertically shear zones are typically between 0.5 and 1.0 meter wide, locally swelling up to 6 meter width. The antimony grades of the stibnite ores vary considerably

2014-3-10 The antimony content of the crude ore varies considerably with 5 – 10 % Sb metal content being a typical given average. However the antimony ores may be much richer in places, reaching > 20 % Sb metal content in some portions of the veins. The cut off is 2 % Sb with poorer ore grades regarded as waste material.

Iron ore, coke and lime are added to the top of a furnace. Hot air is blown in from the bottom. The furnace operates at a high temperature (around 1200°C). Iron ore reacts with carbon/coke to form iron metal and carbon dioxide. The iron is tapped off at the bottom of the furnace.

2012-10-5 Outside its borders, as Source A and Source B both pointed out, the declining grades will continue to mean that China increasingly turns to foreign antimony ore of higher grade to supplement domestic stock. Case in point, as Source A noted, was China Minmetal's purchase of the Beaver Brook antimony mine in Newfoundland, Canada, a few years back.

2021-8-1 Antimony mainly occurs as stibnite (Sb 2 S 3) in a variety of intermediate-low temperature hydrothermal ore deposits worldwide and has been the simplest matrix to analyze. Scant Sb isotopic data from stibnite exists in the literature described above, yet the key controls of its isotope fractionation in these systems are still largely unknown.

The trenching was followed by churn drilling (Ebbley and Wright, 1948, p. 23). Further exploration work was done in 1943 and 1944. The reserve developed by Bureau of Mines drilling and trenching totaled about 10,000 tons grading 9.4 percent antimony, and 6,700 tons of partly developed ore containing about 10 percent antimony (Bain, 1946, p. 67).
