Antimony Concentrate AMERICAN ELEMENTS
Antimony concentrate is similar to powder in that it is made up of minute, dry particles of pure substance. Concentrate is also useful in any application where high surface Antimony was later used by alchemists in the form of antimony oxychloride SbOCl, which acted as a powerful emetic and thus became known as “mercury of life” or Antimony Recovery from End-of-Life Products and

Study on Pre-removal Antimony from Antimony–Gold Concentrate
Antimony–gold concentrate is a refractory gold ore, and the direct cyanide leaching efficiency is very low [].For antimony–gold concentrate with high antimony content (Sb > 30%), the volatilization melting of blast furnace and reduction melting of reverberation furnace is generally adopted at present, and the gold is finally enriched in Electrodeposited antimony can be treated with sulfuration–volatilization technology, which causes antimony to volatilize in the form of antimony sulfide. During this process, gold is enriched in the residue, thereby realizing the value-added use of antimony and the recovery of gold. In this study, the thermodynamic conditions of antimony sulfide Minerals Free Full-Text Preparation of Antimony Sulfide and

In 1963, China successfully developed the process of antimony sulfide concentrate volatilization smelting in blast furnace, which was a new technology for antimony production. In 1986, China developed the chlorination–hydrolysis process that directly uses antimony sulfide ore to produce antimony trioxide (antimony white).Materials. The antimony sulfide concentrates were obtained from a domestic antimony smelter in China. The main mineralogical phases present in the antimony sulfide concentrates were Sb 2 S 3 and SiO 2, as shown in Fig. 1.As listed in Tables I and II, the antimony sulfide concentrates contained considerable antimony Analysis of Antimony Sulfide Oxidation Mechanism in Oxygen

Development of a Two-Stage Hydrometallurgical Process for Gold
1. Introduction. Antimonite (Sb 2 S 3) is the primary industrial mineral for antimony and is often associated with gold in various ways.Depending on the content of gold and antimony, the ores can be classified into different groups [].The selection of a suitable technology is determined by the predominant valuable compounds (gold or The basis of the concentrate is sodium hexahydroxoantimonate or mineral mopungite. Upon reduction of the concentrate with coke, ground antimony containing 0.34% arsenic was obtained. To reduce the arsenic content in the rough metal to 0.1% and exclude the stages of antimony refining from arsenic, reductive melting is proposed in Producing Metallic Antimony with Low Arsenic Content from Antimony
