The End of High-Grade Antimony Reserves in China - the ...

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 ...

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

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).
