The Pb–Zn-Sb ore mineral, which includes lead, zinc, and antimony, holds significant economic value worldwide, with extraction taking place in over 50 countries. These minerals often occur together due to similar precipitation conditions, and sulfide deposits are the primary sources for lead and zinc extraction.
Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from …

stibnite in ore deposits. Here, we present textural relationships, trace element, and in situ antimony isotopic composition of a suite of pri-mary minerals, including native antimony, sulfantimonides, Sb suldes, sulfoxides, and oxides from a deposit camp between Pezinok and Pernek in the Western Carpathians in Slovakia.
Project objectives are to document the origin of the Yellow Pine gold-antimony deposit and, by extension, the origin of this deposit type. Our goal is to understand the structural, tectonic, and magmatic setting of the deposit, the character of the ore-transporting fluids, the conditions of ore deposition, and the regional stratigraphic …

This study investigated the leaching and electrowinning of antimony from a complex, high arsenic and gold-containing stibnite concentrate ore (As-Au-Sb ore) using slurry electrolysis (SE).
An ore deposit is a mineral deposit that can be produced to make a profit. Thus, all ore deposits are mineral deposits, but the reverse is not true. ... aluminum, antimony, barite, beryllium, bismuth, chromium, cobalt, copper, ... We can depict sulfide associations using triangular composition diagrams. Box 9-4 (below) presents a detailed ...
Antimony ore tailings contain Sb, As, Hg, and other heavy metals [1-4] that are highly toxic [5-7]. Previous reports have ... and composition of antimony ore tailings before and after the static and dynamic leaching experiments were observed by transmission electron microscopy (JEOL JEM-2800, Japan), x-ray diffraction (XRD, SMART ...

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.
Tetrahedrite or Gray Copper Ore. Part of the list of all Antimony Minerals Group is Cu2Sb8S7. — Color, grayish or grayish black; powder, grayish or grayish black, sometimes inclining to brown or reddish; luster, metallic; H = 3 to 4; G=4.4 to 5.1; no cleavage; composition, about 52% copper, and, in addition to the antimony and …
It is known that antimony and its oxides are easy to volatilize (Cui et al., 2008a,b), and both exhibit significant vapor pressure above 1073 K. Arsenic is often associated with antimony ore due to their similar chemical properties; in addition to being toxic, arsenic is also volatile (Chen et al., 2012; Awe and Sandstrom, 2010). Thus, smelting ...
Therefore, green and clean preparation of antimony sulfide from heterogeneous antimony sulfide ore, and removing the smelting pressure of single high-grade antimony ore, is a pressing issue that must be addressed (Henckens et al., 2016b).
A native element, antimony metal is extracted primarily from stibnite, which contains 72 percent antimony and 28 percent sulfur. Stibnite is mined in only
The native antimony forms a complete solid solution with native arsenic above 300 °C. The antimony-arsenic solid solution decomposes into a mixture of stibarsen (formerly allemontite) + …
21. In the metallurgy of antimony, the pure metal is recovered via different reactions, depending on the composition of the ore. For example, iron is used to reduce antimony in sulfide ores: Sb,5(s)3Fe(s) 25b(s) 3FeS(s) AH125 kJ Carbon is used as the reducing agent for oxide ores: Sb40s(s)6C(s) 4Sb(s)6CO(g)+778 kJ Calculate ASr for each of ...
In this work, we investigated in situ isotopic compositions of antimony (Sb) minerals from two substages of the ore deposits near Pezinok (Slovakia).
Antimony (Sb) is a valuable mined commodity, used mostly in fire retardants, and considered a critical element. It is also a potential environment hazard classed as a carcinogen.

The ore bodies mainly occur in lamellar, quasi-lamellar and lenticular forms in the altered rocks, and are strictly controlled by anticline structure. In terms of space, elemental paragenesis-separation takes place between gold and antimony deposits, i.e. the gold deposit has antimony ore spots, and the antimony deposit has gold ore spots.
The elemental composition of the ores analysed, leads us to conclude that the use of stibnite in ancient industries would not contribute many elements to the end product other than Sb and S. Based on their ubiquity in ore deposits, only the tetrahedrite-tennantite s.s. and boulangerite are likely other ore minerals to be used.
