The South China antimony ore belt is the largest ore belt in China, accounting for 60% of the world's proven reserves of antimony (Zhang et al., 2020). ... Then the reduced sulphur combined with Sb from the Dachang member and its overlying basalt, precipitated, and formed the antimony deposit. 5.4.3.

The average ε 123 Sb value of basalt was 2.12ε, and the variation range of ε 123 Sb of the profile sample was −4.85ε to 2.19ε, with ZJ-12 (1.8 m depth), showing the most positive ε 123 Sb value of + 2.19ε. Except for ZJ-12, the isotopic compositions of Sb in the soils were lighter than those of the basalt. Strong leaching of alkali and alkaline earth …

Expand/collapse global location. 12.3: Ore Genesis. Page ID. The various theories of ore genesis explain how the various types of mineral deposits form within the Earth's crust. Ore genesis theories are dependent on the mineral or commodity. Ore genesis theories generally involve three components: source, transport or conduit, and trap.

We believe that the gas reservoir formed by the evolution of the oil reservoir in the ore field participated in antimony mineralization; that is, hydrocarbon organic matter acted as a reducing agent and …

A lack of knowledge about antimony (Sb) isotope fractionation mechanisms in key geochemical processes has limited its environmental applications as a tracer. Naturally widespread iron (Fe) (oxyhydr)oxides play a key role in Sb migration due to strong adsorption, but the behavior and mechanisms of Sb isotopic fractionation on Fe …

In Qinglong ore field, the paleo-oil reservoir is found to be associated with antimony deposits, and they have a close genetic relationship. In this study, the aromatics geochemistry of paleo-oil reservoir bitumen was studied to further discuss the thermochemical sulfate reduction (TSR) reaction and the mechanism of antimony …

The ore-forming fluid was rich in radiogenic87 Sr and depleted in radiogenic 143Nd relative to the Emeishan basalt, which rules out the possibility that the Emeishan basalt supplied most of Sr and ...

Antimony. Although antimony ore is not produced in Texas, antimony ores are processed at a smelter in El Paso. Asbestos. ... Basalt. Intrusive masses of basalt are present in several counties along the Balcones Fault Zone and in the Trans-Pecos area of West Texas. It is produced for aggregate, road ballast, and road material in Uvalde County.

The chief ore of antimony is stibnite (Sb 2 S 3, Sb 71.4%). It is more commonly obtained as a by-product in lead-zinc-silver mines. The resources have ... weathering of deccan trap basalt, archaean felspathic gneisses and granulites, etc. Bauxite is the only mineral raw material from which aluminium is extracted economically.

The best metal ore minerals are those that contain large amounts of metals of value. Most metallic ore minerals are native elements, sulfides, sulfosalts, oxides, or hydroxides. Ore deposits are highly variable in nature and origin. The most important kinds of ore deposits are magmatic, hydrothermal, and sedimentary.

In the past the mines have depended largely on ore that could readily be hand-sorted to a shipping-grade product containing more than 30 percent of anti­ mony. Since 1940, however, ore containing as little as 18 percent of antimony has been shipped. As ore bodies are not developed and blocked out in advance of mining, being

stibnite, antimony sulfide (Sb 2 S 3 ), 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 about 525° C [977° F]). It often possesses a bladed habit, is striated, and has one perfect cleavage. Stibnite occurs in massive forms in gneiss and granite.
