Antimony is increasingly being identified as a toxic environmental pollutant and has been implicated in cancer development (Foy et al, 1978, Gurnani et al, 1994, Gebel, 1997)The principal global sources of anthropogenic antimony pollution are the mining and smelting industries (Adriano, 1986), and very high levels of pollution have been
SK Haldar, in PlatinumNickelChromium Deposits, 2017 11532 Smelting Smelting is necessary to maximize the separation of the gangue (oxide and silicate) minerals from the sulfide minerals associated with the noble metals Flotation concentrates undergo smelting and converting in a furnace at a temperature exceeding 1300°C to produce a silicate melt (slag) and an immiscible sulfide melt

Feb 01, 2011· The main purpose of this study is to characterize and separate antimony from a stibnite concentrate through a lowtemperature sulfurfixing smelting process This article reports on a study conducted on the optimization of process parameters, such as flux and zinc oxide weight percentage, in charging, smelting temperature, smelting duration on the antimony yield, resultant crude antimony
Mar 16, 2011· The major hazards are exposure to ore dusts during ore processing and smelting, metal fumes (including lead, arsenic and antimony) during smelting, sulphur dioxide and carbon monoxide during most smelting operations, noise from grinding and crushing operations and from furnaces, and heat stress from the furnaces
like the title says, how important is it to use wax, or wood chips to flux while smelting? i always stir the lead until the clips and crud are separate from the melted lead, and everything is mixed in well i use a steel rod to mix the clips and weights till it is melted is it essential to flux while smelting? i use paraffin wax to flux in my bottom pour furnace while casting though
Feb 08, 2016· Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3) The industrial importance of antimony is mainly derived from its use as flame
Nov 25, 2018· Hello all I have a question for those better than myself here I have stumbled upon a small quantity of pure antimony and i know that is what is used to harden, waterquench bullets I tried to make a batch of hardball equivalent lead alloy (2%tin, 6%antimony, and 92% lead) and I was unable to get the antimony to melt and flux/mix in
