·Exploration for Antimony Deposits in Southern Tuscany Italy R M Dehm D D Klemm C M[Jller J Wagner and K Weber Diefenbach which generally are expected to be the primary source of antimony From these pre Variscan units antimony was remobilized and transport ed hydrothermally to its present position 1 GEOLOGICAL SETTING AND
·Large Sb mines are located in the ZR Basin including the Longshan Sb Au mine Xikuangshan Sb mine Gutaishan Sb mine Zhazixi Sb mine and Banxi Sb mine from upstream to downstream Fig 1 and Table S1 The Longshan Sb Au mine is located in the Longshan Shaoshui catchment and the wastewater from this mine flows into the ZR between sampling
Stibnite is commonly found as one of the primary ore minerals in most antimony deposits and it can even occur as the sole ore mineral in some large antimony deposits; therefore sulfur isotope
The idealized prototype of a southern Tuscan antimony deposit can be described as follows The irregular mineralization is situated in the upper part of the highly porous Calcare Cavernoso overlain by an impermeable unit normally a flysch type rock The deposits are bound to the edge of horst positions and also to areas of elevated geothermal gradient and resulting
·The Kharma antimony deposit in the Cordillera Oriental Bolivia is representative of vein type antimony deposits that have stibnite as the only mineral of economic interest and a low gold content In this deposit recovery of gold is difficult because it is not known exactly where the gold is located within the ore shoots or the manner in which it is present in the main

·China is one of the first countries in the world to discover and mine Sb deposits ≪Chinese mineral deposits≫ editorial committee 1989 Antimony reserves and production are abundant in China Niu et al 2012 which ranks first in the world and play a significant role in the global production and trade of Sb Zhou et al 2014
5 ·Located in western Slovakia it potentially hosts one of the European Union s most significant known primary antimony deposits 63 holes were historically completed into the deposit during the 1980 1900s over a strike length of kilometers along with nearly kilometers of underground workings; the deposit hosts historical non
Remarkably there is a distinct disparity in the distribution of Sn deposits across Thailand In the eastern regions dominated by granitic rocks Sn deposits are almost absent Fig 1 In sharp contrast the granitic formations along the Thai Myanmar border in western central Thailand host numerous economically substantial Sn ore deposits Hutchison and Taylor 1978 Lehmann et
The Sulfur and lead isotopic compositions of stibnite from Banian antimony deposit located in Dushan County Guizhou Province one of representative antimony deposits in the South China Sb belt whose orebodies hosted by the Dushan Formation of the Middle Devonian were systematically analyzed in this results show that δ34S values of stibnite range from
Classification and Distribution of Antimony Deposits in China Xiongwei Hu 1 Satoshi MURAO Mingkui SHI and Buo LI Abstract China ranks the first in the world both for antimony production and its reserves There are about 600 occurrences in China Based on the occurrence mode of ore five types are distinguished for the antimony deposits
·Antimony can be re covered as either a primary commodity from some deposits or as a by product commodity from some gold or silver deposits Environmental risks associated with antimony mining include those related to mining in general such as the acid generating potential of solid mine waste and some issues specific to antimony as described
·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 selection for a greenfield plant
The quartz stibnite scheelite and quartz stibnite cinnabar associations are characteristic of the calcareous formations of Paleozoic age whereas the quartz antimony mercury assemblage occurs only in the lower Carboniferous of the Cantabrian Iberian antimony deposits are interpreted to be the result of direct or indirect magmatic
