Mineral Commodity Profiles: Antimony
antimony plummeted during the early years of the Depression of the 1930s but recovered after a few years and then climbed sharply during the late 1930s as global conflict threatened again. Recovery of demand in the United States was somewhat more protracted. Antimony was again used in large quantities in World War II when world demand

How to melt antimony Gunloads
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.
Antimony Statistics and Information
The natural sulfide of antimony was known and used in Biblical times as medicine and as a cosmetic. Antimony in its elemental form is a silvery white, brittle crystalline solid that exhibits poor electrical and heat conductivity properties. Commercial forms of antimony are generally ingots, broken pieces, granules, and cast cake.
Pollution Characteristics of Sb, As, Hg, Pb, Cd, and Zn in
Major sources of pollution during the antimony (Sb) mining and processing are mining waste rock, smelting waste, tailings dam, and underground tunnel wastewater. The aim of the present study was to assess magnitude of pollution from Sb mine by taking four types of samples: soil in the mining waste rock zone, soil in the smelting zone, soil in tailings zone, and soil in underground tunnel

Antimony Trioxide [CAS No. 1309644] Brief Review of Toxicological Literature during processing and packaging of antimony compounds and during processing and smelting of antimony ores, and limits for workplace exposure are set for antimony compounds as a group (0.5 mg Nomination Background Information: Antimony Trioxide [Cas No. 1309
Lead smelting Wikipedia
The Roman lead smelting has led to evidence of global pollution. Greenland ice cores from 500 BCE to 300 CE show measurably elevated lead content in the atmosphere. In the USA there are 400 forgotten lead smelting firms that operated in the 1930s to 1960s and may have deposited dangerous levels of lead contamination in nearby soil.
12.3 Primary Copper Smelting
A typical pyrometallurgical copper smelting process, as illustrated in Figure 12.31, includes 4 steps: roasting, smelting, concentrating, and fire refining. Ore concentration is roasted to reduce impurities, including sulfur, antimony, arsenic, and lead. The roasted product, calcine, serves as a dried and heated charge for the smelting furnace.
PAPER OPEN ACCESS Melting of crude antimony in the low
precipitation smelting of antimony ore is based on the great affinity of sulfur and oxygen to iron, rather than to antimony. The main purpose of meltings the antimony raw materials is the transfer of the main substance of ore – antimony in a less contaminated by iron
AP42, CH 12.11: Secondary Lead Processing, updated tables
Refining and casting the crude lead from the smelting furnaces can consist of softening, alloying, and oxidation depending on the degree of purity or alloy type desired. These operations are Antimony, tin, arsenic, copper, and nickel are the most common alloying materials.

U.S. Antimony Reports Antimony Prices and Production
Mar 06, 2017 · Compared to 2016, antimony production was lower in Mexico during January and February 2017 due to the transition from the custom smelting to
Working with antimony question (total noob) Smelting
Jan 16, 2013 · Antimony is used in lead bullet alloys IIRC, linotype is about 84% lead, 12% antimony and the balance is tin. One issue with melting and casting is that when the metal does finally melt, it does so immediately and you can have a potentially dangerous situation if you aren't prepared for that event.
