Jul 17 2012 Antimony has been produced from ores in over 15 countries. As shown in Table 2 Carlin 2012 world reserves of antimony are estimated to about 1.8 million metric tonnes.As China the leading producer accounts for about 90 of the worlds mined production and the vast majority of the reserve base i.e. reserves consist of demonstrated resources that are currently economic.
6 Iron sulfide ores Gold occurs as liberated particles attachments to and inclusions in sulfide commonly in pyrite and . type ores 8 Antimony sulfide ores Gold occurs mainly as native gold with minor . by roasting a flotation concentrate followed by cyanidation Wang et al. 1994.
Antimony is often found in other ores as well e.g. silver copper and lead. The pure element antimony is produced from the ore by roasting it to form the oxide then reducing the oxide with carbon or iron often a flux of sodium sulfate or sodium carbonate is used to prevent loss of molten antimony

Antimony Ore Processing Methods. In another method that has been suggested the alloy is treated with metallic sodium in order to form an alloy of sodium and antimony this is dissolved in molten caustic soda and the antimony separated by treatment with water more than threequarters of theAntimony Ore Processing Methods.

The process works best when the ore is crushed to small pieces before roasting. Additives such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted and the sulfur is driven off the extraction of the gold or silver from the ore is not especially difficult.
Detailed mineralogical characterization of the Akoluk gold-silver ore has indicated that the ore contains antimony sulfides including andorite Sb 3 PbAgS 6 and zinkenite Pb 9 Sb 22 S 42 as .
The concentrated enriched ore can contain up to 35 copper and a number of impurities such as antimony arsenic and lead. Roasting reduces impurities in the copper ore and produces calcine a mixture of products Concentrated enriched ore is heated to between 500 o C and 700 o C in air.

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 retardant in plastics coatings and
The result is not just lead sulphide but also the sulphides of copper iron zinc antimony and arsenic. The enriched ore is then roasted in ovens to drive off as much of the sulphur as possible. The roasted ore must be ground and sintered to put it in the form of porous chunks that allow gases to pass through freely and will not collapse .
Extraction of Antimony. Antimony is extracted mainly from ores containing antimony trisulphide in the form of stibnite. Rich ores are first subjected to liquation whereby the fusible sulphide is removed from the gangue and concentrated. The concentrate is then reduced to metal by smelting with wrought iron in pots in reverberatory furnaces or .
Improved gold and silver extraction from a refractory antimony ore by pretreatment with alkaline sulphide leach. By Haci Deveci and ibrahim alp. Implementation of sodium hydroxide pretreatment for refractory antimonial gold and silver ores. By ibrahim alp. Application of Diagnostic Leaching Technique for Refractory Gold Ores.
Extraction from the ore The metal antimony was produced from the ore by first roasting it to form the oxide then reducing the oxide with carbon or iron Antimony compounds especially the trisulphide were used in antiquity for example Kohl al-kohl of the Arabs used to stain the eyelids.

antimony trioxide is either purified in reverberatory furnace to produce pure antimony oxide or reduced with some carbon source by smelting at high temperature 1150oC to 1350oC to produce antimony metal. The metal is re-volatilized to produce pure antimony trioxide. Roasting and smelting of antimony ores under high temperature creates serious .
Apr 21 2020 The inhibitor of iron ore uses the sodium silicate tannin and sodium lignosulfonate and their inhibitory effect is the best when the pH value is 8-9. In terms of the ore properties of hematite ore the reverse flotation method is more advantageous as the method used for the extraction of iron from hematite than the positive flotation method.
Mar 17 2020 High sulfide gold ore refers to a certain gold ore with 20 -30 of gold wrapped by sulfide mainly pyrite. Because most of the gold in high-sulfide gold ore exists in the form of sulfide-encapsulated gold when using direct leaching process the consumption of gold leaching agent and cost of gold leaching production will increase and gold processing efficiency is not good.
