Antimony is used as a hardening agent in lead alloy, which is consequently used in lead storage batteries, munitions, industries, wear-resisting bearings etc. Antimony compounds are utilized in flame retardants, semiconductors, and pharmaceuticals (Awe and Sandström, 2013; Multani et al., 2016).
Metallic antimony is used as a hardening agent for lead and its use in lead storage batteries accounts for around one third of global use. Antimony alloys are also used for manufacturing solder, sheet and pipe metal, ammunition, bearings, castings and pewter.
The most common antimony ore mineral is stibnite (Sb2 S3 ), but more than 100 other minerals also contain antimony. The presence of antimony in surface waters and groundwaters results primarily from rock weathering, soil runoff, and anthropogenic sources. Global emissions of antimony to the atmosphere average 6,100 metric tons per year.
Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.

small amounts of antimony in many sulfide ores of lead; if the antimony content of the ore is high enough, these ores may be smelted directly to a hard lead; or if small, the antimony content is removed from the lead in the refining process, and is recov-ered separately. The ores vary widely in richness, and the subsequent treatment depends ...
as a fuel and smelts the lead-containing materi-als. The molten lead flows to the bottom of the furnace, where four layers form: "speiss" (the lightest material, basically arsenic and antimony), "matte" (copper sulfide and other metal sulfides), blast furnace slag (primarily silicates), and lead bullion (98% by weight). All layers are then
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 and bismuth. …
The mined antimony ore is generally broken into crushed stones with a certain particle size and used for artificial beneficiation. ... Chen, T.; Yan, B.; Li, L.

antimonial lead, containing from 4 to 12 per cent of antimony, produced either by alloying the two metals or, more often, by the smelting of antimonial lead ores or a mixture of …
Lead and zinc can be produced pyrometal- lurgically or hydrometallurgically, depending on the type of ore used as a charge. In the pyromet- allurgical process, ore concentrate containing lead, zinc, or both is fed, in some cases after sin- tering, into a primary smelter.
Lead acetate is sometimes used to throw down sulphide. Rose and Newman refer to several methods for the treatment of antimonial and arsenical ores. These include leaching with caustic soda, roasting, …
Stibnite is a sulfide minerals with chemical composition is antimony sulfide (Sb2S3). The principal ore of antimony. 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.
Antimony sulphide (stibnite) is the main ore of antimony having silvery, grey glittery appear-ance that is very brittle and has a flaky texture. Whereas, the lead sulphide is …

Compared with metals, antimony is a poor conductor of electricity and heat. Antimony is the 63rd-most abundant element in Earth's crust. It is less abundant than tin, arsenic and the rare earths, but more so than bismuth, mercury and silver. Antimony tends to concentrate in sulfide ores along with copper, lead and silver.
Lead is extremely resistant to atmospheric corrosion as it rapidly becomes covered with an impervious film of oxides, carbonates, and sulfates. Lead was used for water pipes and …
In general, sulfide ores are volatilized as oxides; 25–40% antimony ores are smelted in a blast furnace; and 45–60% antimony ores are liquated or treated by iron precipitation. The blast furnace is generally used for mixed sulfide and oxide ores. Antimony is often found associated with lead ores.
The antimony content of ores, which ranges from 5 to 60 percent, determines the method of recovery. In general, the low-est grades of sulfide ores, which have from 5 to 25 percent an-timony content, are roasted to form antimony oxides; ores that have to 25 or 40 percent antimony content are smelted in a blast
