Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. The product represented by this dataset is antimony metal, a brittle semi-metal with a silver-white color and a slight blue luster, having the physical characteristics of high hardness, poor ductility, and average electrical and thermal conductivity; it has good chemical stability at room temperature and excellent acid and alkali corrosion resistance, making it an important basic material and strategic mineral needed for the national economy, national defense industry and scientific and technological development. Its upstream and downstream industries are closely related: the upstream core raw material is antimony concentrate, and the auxiliary raw materials include reducing agents, fluxes, refractory materials, etc.; the downstream application scenarios are diverse and critical, mainly used in the flame-retardant field (with antimony trioxide as a synergist for plastics, rubber and textiles), followed by lead-antimony alloy production (suitable for scenarios such as lead-acid battery plates, bearings, solders, and casting), while also being indispensable in chemical catalysis (polyester PET catalysis) and electronic semiconductors (as a dopant and arsenide/antimonide compound semiconductors); in addition, high-purity antimony metal and antimony-based materials play an increasingly important key role in emerging low-carbon technologies such as liquid metal energy storage batteries, sodium/lithium-ion battery alloy anodes, thermoelectric materials, and antimony-based thin-film photovoltaics. The entire production process focuses on the antimony ore smelting stage, covering the entire conversion process from antimony concentrate to the antimony metal product. The dataset includes the main raw and auxiliary materials, energy and waste of the production process, while infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources.
Activity Description
The entire production process includes the antimony ore smelting process, covering the entire process from antimony concentrate to metallic antimony.
Process Description
Antimony is a brittle semi-metal that is silvery white with a slight blue luster. It has high hardness but poor ductility. It has average electrical and thermal conductivity. It has good chemical stability at room temperature and is resistant to acid and alkali corrosion. It is regarded as an important basic material and strategic mineral required for the development of the national economy, national defense industry and science and technology. Metal antimony and its compounds are mainly used in the field of flame retardancy (antimony trioxide is widely used in plastics, rubber and textiles as a synergist), and are secondarily used in lead-antimony alloys (lead-acid battery plates, bearings, solders, castings, etc.) and chemical catalysis (polyester PET catalysis) and electronic semiconductors (as dopants and arsenide/antimonide compound semiconductors). At the same time, high-purity metal antimony and antimony-based materials also play an increasingly important and key role in emerging low-carbon technologies such as liquid metal energy storage batteries, sodium/lithium-ion battery alloy anodes, thermoelectric materials, and antimony-based thin-film photovoltaics.

Technology comment
Antimony ore smelting adopts the "blast furnace volatilization smelting-reverberatory furnace reduction refining" route in the pyrometallurgical smelting process, that is, the antimony concentrate is oxidized into antimony oxide in the blast furnace, the antimony oxide is reduced to crude antimony in the reverberatory furnace, and the crude antimony continues to be refined into 99.9% metal antimony ingots in the reverberatory furnace. During the production process, a large amount of energy such as electricity, coke, and coal is consumed, and environmental protection facilities such as condensation dust removal and desulfurization are required to control flue gas emissions.
