Nov 30, 2018· Perhaps this was from a lack of experience and that my technique wasn't very refined at the outset I started by taking the ore of antimony, stibnite, which I obtained in crystal form from China This particular ore had a lot of impurities in it, including calcite and quartz (which in the end benefited me quite a lot, as will be explained shortly)...
antimony sulfide ore was smelted, persnal1W A airrne concentrations of antimony were 092-707 mg/m3; the author postulated a predominance of antimony trioxide (Renes, 1953) At another US antimony smelting plant, workers were expsed to antimony ore dust contain-ing priariy antimony trioxide at concentrations (area samples) ranging from 008 to 138...
METALLURGY LIQUATION: Liquation is the melting of stibnite into “crudum” or “needle antimony” It is carried out between 550 and 600 degrees C If the temperature is lower, the recovery is poor If the temperature is any higher, the stibnite volatilizes into oxide This method is ,...

Pliny described how stibnite could be used as a medicine and how, if heated too strongly, it would turn to lead We understand now that the ‘lead’ described by Pliny is actually the element antimony, produced by heating its ore (2) In the first half of the 1500s, Italian metallurgist Vannoccio Biringuccio wrote the ,...

Stibnite is a lead-gray mineral, usually occurring as striated prismatic crystals, that are made up of antimony sulfide and is the main ore of antimony It often forms groups of long, shiny metallic crystals radiating out at different angles, which look like something out of a sci-fi movie...
The effects of arsenic and antimony sulphide minerals on the extraction of gold from a synthetic ore consisting essentially of free gold and glass sand were investigated The amount of mineral added in each test was such that the synthetic ore assayed 025% As or 025% Sb...
