First, the sulfide concentrate is roasted in air to oxidize the lead sulfide: 2 PbS(s) + 3 O 2 (g) → 2 PbO(s) + 2 SO 2 (g)↑ As the original concentrate was not pure lead sulfide, roasting yields not only the desired lead(II) oxide, but a mixture of oxides, sulfates, and silicates of lead and of the other metals contained in the ore.
Meneghinite is a rare mineral that generally forms interesting acicular crystals. Meneghinite is one of several lead antimony sulfides. The elements lead, antimony and sulfur have the capability of forming many different minerals. There are at least a dozen different minerals with just lead, antimony and sulfur comprising their chemistries.
Antimony is found in trace amounts in silver, copper and lead ores, and it is usually economically possible, as well as environmentally desirable, to extract the antimony from these ores when they are smelted. Most of the antimony mined each year comes from China, which supplies over three-quarters of the world's total.
Sulfide (British English also sulphide) is an inorganic anion of sulfur with the chemical formula S 2− or a compound containing one or more S 2− ions. Solutions of sulfide salts are corrosive. Sulfide also refers to chemical compounds large families of inorganic and organic compounds, e.g. lead sulfide and dimethyl sulfide.
Collectable Copper Ores and Minerals. This is a selection of the most commonly collected copper ores. Also included are a few other interesting ores of metals often alloyed with copper such as zinc, lead …
Bindheimite is an alteration product, or more specifically an oxidation product of lead antimony sulfides such as jamesonite, Pb4FeSb6S14 and boulangerite, Pb5Sb4S11. Sometimes it pseudomorphs these minerals meaning that it replaces them without to much distortion of the outward appearance of the crystals.

Galena, the most common mineral of lead, is primarily lead sulfide (PbS).The sulfide is oxidized to a sulfite (PbSO 3) which thermally decomposes into lead oxide and sulfur dioxide gas.(PbO and SO 2) The sulfur dioxide (like the carbon dioxide in the example above) is expelled, and the lead oxide is reduced. Anglesite, Cerussite, Pyromorphite, Mimetite and Wulfenite are other lead ores.
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 sometimes in blast ...
antimony sulfide ore was smelted, persnal1W A airrne concentrations of antimony were 0.92-70.7 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 0.08 to 138
It is extremely important when treating high sulfide ores with cyanide to keep a sufficient protective base in the solution. Many sulfide minerals also contain things like copper or antimony that can react with the cyanide, preventing the cyanide from leaching out the gold and silver.
The invention discloses a flotation separation method of antimony sulfide and gold-bearing pyrite. Sodium hexametaphosphate is adopted as a dispersing agent, sodium silicate is used as a silicon and calcium gangue inhibitor, copper sulfate is used as an antimony and gold mineral activating agent, butyl xanthate is used as a collecting agent, and No. 2 oil is used as a …
Most sulphides are oxidized to sulphate. From the sulphated ore, all of the zinc, copper and iron can be leached with water while lead, silver, gold and antimony will remain in the insoluble residue. Leaching of an Arsenical Copper Sulfide Concentrate
Antimony Ore any of the natural mineral formations containing antimony in compounds and concentrations that make commercial use technically and economically feasible. Of the antimony ores proper, the major mineral is antimonite (Sb2S3), which contains up to 71.4 percent Sb; in rare cases, antimony ores are represented by complex sulfides of antimony ...
Stibnite – antimony or antimony trisulfide, ore of antimony; Sugar of Lead – lead(II) acetate, formed by dissolving lead oxide in vinegar; Sweet Vitriol – diethyl ether. It could be made by mixing oil of vitriol with spirit of wine and heating it. Thion Hudor – lime sulfur, formed by boiling flowers of sulfur with slaked lime
The principal ore of antimony, stibnite is antimony sulfide. Its name comes from the Latin stibium. Lead-gray to silvery gray in color, it often develops a black, iridescent tarnish on exposure to light. It normally occurs as elongated, prismatic crystals that may be bent or twisted.
Alibaba.com offers 156 antimony sulfide products. About 25% of these are sulfide, 1% are other organic intermediates, and 1% are rubber auxiliary agents. A wide variety of antimony sulfide options are available to you, such as industrial grade, agriculture grade, and electron grade.
Sulfide ore or liquated antimony sulfide is reduced to metal by iron precipitation. Antimony trioxide may be volatilized from sulfide ores, and can be reduced to metal with charcoal in reverberatory furnaces. Antimony product may also be produced by blast furnace smelting or hydrometallurgical methods.
The successful cyanidation of gold ores containing appreciable amounts of arsenic or antimony sulphide minerals such as orpiment, realgar, and stibnite is usually difficult or even impossible. Extractions are low and the solutions soon become 'foul.' The gold in such ores could be free and uncoated, and no trouble in dissolving it in clean cyanide solutions would be expected.
The extraction of antimony from ores depends on the quality and composition of the ore. Most antimony is mined as the sulfide; lower-grade ores are concentrated by froth flotation, while higher-grade ores are heated to 500–600 °C, the temperature at which stibnite melts and separates from the gangue minerals.

Antimony trisulfide (Sb 2 S 3) is found in nature as the crystalline mineral stibnite and the amorphous red mineral metastibnite. It is manufactured for use in safety matches, military ammunition, explosives and fireworks. It also is used in the production of ruby-colored glass and in plastics as a flame retardant.
I could tell you about its moderately fascinating role in the history of eye make-up. I could tell you about its glittering career as a fuel in fireworks. I could even tell you about the strange pattern known as the 'Philosopher's signet star' that forms when stibnite - antimony sulfide ore - is used for extracting metallic antimony.

The dark red silver ore is a sulphide of silver and antimony ; the light red contains arsenic in the place of antimony. The ores of silver occur in veins traversing granitic and gneissic rocks, clay slate, mica schist, limestone, and are usually associated with the ores of iron, copper, load (galena being always argentiferous), zinc.
