· Antimony is used as the primary hardening element. Pure lead is the cheap part; it has a Brinell hardness if 8.6. To illustrate the formula: Let''s say we alloy pure lead to arrive at a composition with 4% tin and 4% antimony. So, Bhn = 8.6 + 4 (0.3) + 4 (0.9). So this alloy would have a Brinell hardness of 13.4.
Antimony compounds are prominent additives for chlorine- and bromine-containing fire retardants found in many commercial and domestic products. An emerging application is the use of antimony in microelectronics. Shipment/storage. Ore concentrate or residue of the element antimony. A high density lead-grey mineral, subject to black tarnish.

Antimony | Minerals Education Coalition
Antimony also is used as an alloy, because it hardens other metals. Alloyed with lead, it greatly improves the strength and hardness of lead. It also is used in semiconductors, diodes, infrared detectors, batteries and bullets. Antimony compounds are used in paint pigments, enamels, glass and pottery.
Antimony Statistics and Information
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.
Stibnite: The mineral stibnite information and pictures
Stibnite is named after the latin stibium, which is the old name of the element antimony (Sb). Stibnite was and continues to be the primary ore of antimony. Stibnite forms some of the most outstanding natural crystals that exist, in way of sharpness, luster, and size can form in groups of huge metallic lustered crystals that are elegantly crafted and exceptionally shiny.
3 Antimony Ore Beneficiation Process
· Antimony ore can be divided into antimonite, cubismite, antimony ochre, etc. Due to the difference in the nature of the ore, the process used is also different. Commonly used beneficiation processes include manual separation, gravity separation and flotation . This article briefly introduces these three commonly used antimony ore beneficiation processes.
Antimony. Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle; the non metallic form is a grey powder. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis.
Antimony is an important mineral commodity used widely in modern industrialized societies. The element imparts strength, hardness, and corrosion resistance to alloys that are used in many areas of industry, including in lead-acid storage batteries. Antimony''s leading use is as a fire retardant in safety equipment and in goods, such as mattresses.

· When used as an alloying element, antimony greatly increases the hardness and mechanical strength of lead. The main use of antimony is to harden lead in storage batteries, and it is increasingly being used in the semiconductor industry. Historically and economically, antimony is the second most important metallic commodity in Victoria, after gold.
Barite Mineral | Uses and Properties
Barite is also a common mineral in hydrothermal veins and is a gangue mineral associated with sulfide ore veins. It is found in association with ores of antimony, cobalt, copper, lead, manganese, and silver. In a few locations barite is deposited as a sinter at hot springs.

percent. Northover does not speculate on the ore sources that might have been smelted to produce these ternaries, but the presence of both arsenic and antimony in high concentration suggests a weathered tetrahedrite-type ore [Cul12(As,Sb)4S13].

TOXICOLOGICAL PROFILE FOR ANTIMONY AND COMPOUNDS
Antimony is a silvery white metal of medium hardness that breaks easily. Small amounts of antimony are found in the earth''s crust. Antimony ores are mined and then either changed into antimony metal or combined with oxygen to form antimony oxide. Antimony oxide is a white powder that does not evaporate. Only a small amount of it will dissolve ...

effect on hardness of lead with antimony and tin
· There has always been discussion here about what is the hardness of a lead mixture with certain amounts of antimony and/or tin. I don''t have a simple formula for that. Some years ago, I got a bunch of almost chemically pure lead (roofing lead). I also had pure tin and a bunch of monotype with a set quantity of antimony in it. At the time, I also had three hardness testers (SAECO, Potter, and Lee).

· In summary, the pre-ore Py1 is featured by having the lowest Au, As, Sb, Cu and Ag contents (commonly bdl), compared to the syn-ore Py2 and Py3. Early-ore Py2 is richer in these elements than late-ore Py3. In addition, the average Co/Ni values increase from 0.31 in Py1, through 1.75 in Py3, to 1.97 in Py2.

The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.

Antimony – resists heat, draws criticality
While roughly 100 tons of ore from mining shipped from Sliscovich in 1914 and 1915 contained about 35 percent antimony, the value of the gold and silver in this ore outweighed the critical mineral. "Antimony is often a high-level indicator of deeper gold deposits," said Barker.
Antimony Uses and Facts. B.C. Articles made before Antimony until 3000 years. The first published report on how to isolate antimony was made in 1540 by Vannoccio Biringuccio. Antimony''s periodic symbol comes from Jons Jakob Berzelius, who uses the abbreviation stibium. Antimony is stable at normal temperatures, but reacts with oxygen when heated.
