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 magnesium chloride from titanium sponge production. Its main feature is that it is generated through the participation of a magnesium source (usually magnesium metal or magnesium-containing compounds) in the reaction during the chlorination-reduction process, and is obtained in the form of condensation recovery. Its purity and crystal water content depend on the process cooling method and subsequent treatment level. Its physical form can be crystalline particles or powder, and its chemical properties are strongly hygroscopic, easily soluble in water to form a weakly alkaline solution, and can form double salts with various anions. This product is located at the by-product end of titanium sponge production in the industry chain. Its upstream key raw materials are titanium raw material, magnesium source and chlorine gas, and downstream it can be used as magnesium electrolysis raw material, building material and chemical raw material, snow-melting agent and other diversified applications. 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
This data set covers the entire process of producing magnesium chloride products from by-product magnesium-containing materials in the production process of titanium sponge as raw materials, through separation, purification, concentration, crystallization or drying. The main input is the magnesium-containing waste liquid generated during the production of titanium sponge or the magnesium-containing intermediate generated by the hydrolysis of crude titanium tetrachloride, as well as necessary process water, acid-base regulators, energy and other auxiliary materials; the main output is magnesium chloride products of different specifications (anhydrous magnesium chloride or magnesium chloride hexahydrate), as well as a small amount of by-products or wastewater such as filter residues and evaporation condensate. The main process units include in sequence the collection and pretreatment of magnesium-containing materials, chemical conversion or solid-liquid separation to extract magnesium ions, solution purification and impurity removal, concentration and evaporation to saturation, crystallization or drying to obtain finished products, and finished product packaging and storage.
Process Description
Magnesium chloride is a by-product formed during the production of titanium sponge. Its main component is magnesium chloride hexahydrate (MgCl₂·6H₂O). It can also be made into anhydrous magnesium chloride during subsequent processing. The magnesium content corresponds to the purity of magnesium chloride, which is usually above 90%. Key performance parameters The data include magnesium chloride purity, crystal water content, particle size distribution, solubility, and impurity ion types and contents. The common form is colorless or white crystals or particles, which mainly come from the condensation recovery stage when ilmenite or high-titanium slag is used as raw material and the chlorination-reduction process is used to produce sponge titanium. Magnesium chloride is mainly collected, purified or sold as an industrial by-product in this system. It can be used as magnesium electrolysis raw material in the metallurgical industry, magnesite products in the building materials industry, road snow melting agent, magnesium compound synthesis in the chemical industry, etc. It can also be returned to the chlor-alkali or magnesium smelting cycle system after dehydration treatment. The standard chemical formula is MgCl₂ (anhydrous) or MgCl₂·6H₂O (hexahydrate).
