Antimony is classified as a critical/strategic metal. Its primary production is predominated by China via pyrometallurgical routes such as volatilization roasting—reduction smelting or direct reduction smelting. The performance of most of the pyro-processes is very sensitive to concentrate type and grade. Therefore, technology …

Antimony is also alloyed with tin to make pewter items such as plates, pitchers and cups, used mostly for decoration. One use of antimony, which is declining, is to make type metal for newspapers and magazines. Antimony is one of very few substances (bismuth and water are two others) which expand when it cools and freezes.

The raw material, antimonial refractory gold ore, was provided by the Jinchiling Gold Mine (Zhaojin Mining Industry Co., Ltd., Shandong Province, China). The chemical composition of the ore is given in Table 1. Before the experiments, the ore was dried at 383 K, and then ground and sieved to obtain a particle size below 74 μm.

Stibnite, antimony sulfide (Sb2S3), the principal ore of antimony. This mineral has a brilliant metallic lustre, is lead- to steel-gray in colour, and fuses readily in a candle flame (at …

In this work, we investigated in situ isotopic compositions of antimony (Sb) minerals from two substages of the ore deposits near Pezinok (Slovakia). The δ123Sb values of the primary Sb minerals range from −0.4 and +0.8‰ and increase progressively along the precipitation sequence. In the substage II, the early-formed gudmundite (FeSbS) shows …

What is Galena? Galena is a lead sulfide mineral with a chemical composition of PbS. It is the world's primary ore of lead and is mined from a large number of deposits in many countries. It is found in igneous and …

Antimony. S.C. Gad, in Encyclopedia of Toxicology (Third Edition), 2014 Abstract. Antimony (Sb; CASRN 7440-36-0) is a semimetal element with chemical properties similar to lead, arsenic, and bismuth. In nature, it is found associated with sulfur as stibnite. Antimony is used in white metal, a group of alloys having relatively low melting points.

The chemical composition of contaminated soil is shown in Table 5.1. It is a typical sandy soil, mainly containing SiO 2, but also containing a small amount of CaO, Al 2 O 3, Fe 2 O 3 and MgO. The content of antimony in soil is 24666 mg/kg, and the content of As is 240 mg/kg.
