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. Basic magnesium carbonate is widely used in rubber, plastics, pharmaceuticals, cosmetics, food and chemical industry and other fields; basic magnesium carbonate is modeled as a pure substance, and when modeling this substance the user needs to add a solvent of their choice in the model; this dataset includes the main raw and auxiliary materials, energy, waste and air emissions 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; the production activity of this product includes feeding, ball milling, hydrolysis, pre-carbonation, carbonation, pyrolysis, plate-and-frame pressure filtration, drying and other process steps.
Activity Description
The production activities of this product include loading, ball milling, hydrolysis, pre-carbonization, carbonization, pyrolysis, plate and frame filter press, drying and other processes.
Process Description
The common composition of basic magnesium carbonate is 4MgCO3·Mg(OH)2·4H2O. It is usually white loose powder or amorphous powder, odorless, tasteless and light in texture. It is insoluble in water and ethanol, easily soluble in dilute acid and releases carbon dioxide gas. It reacts with dilute sulfuric acid and hydrochloric acid to form the corresponding magnesium salt. It has relatively stable chemical properties and does not deteriorate easily in the air. It will decompose when heated to above 300°C, losing crystallization water and decomposing magnesium hydroxide into magnesium oxide, ultimately generating magnesium oxide and carbon dioxide. It has good adsorption, dispersion and high temperature resistance, and is non-toxic and odorless. It is widely used in the rubber industry (as a filler to improve rubber elasticity and wear resistance) and the plastics industry (as a flame retardant and filler to improve the heat resistance of plastics); in the pharmaceutical field, it can be used as an antacid (to neutralize gastric acid and relieve stomach pain) and laxatives; it is also used as a toothpaste friction agent, cosmetic filler, and in the food industry as an anticaking agent and stabilizer (such as used in chocolate, flour, etc.), and can also be used to prepare chemical products such as magnesium oxide and magnesium salts.

Technology comment
Mineral processing method is the mainstream technology for the production of basic magnesium carbonate, with controllable process costs. It accounts for more than 80% of the domestic basic magnesium carbonate market. This data set represents this mainstream technology: the raw materials and mother liquor are fully mixed and dispersed in a ball mill and then hydrolyzed to generate magnesium hydroxide. Carbon dioxide is introduced for pre-carbonization and carbonization to generate magnesium bicarbonate. Subsequently, pyrolysis is performed to generate basic magnesium carbonate. Finally, pressure filtration and drying are performed to obtain the finished product. The main chemical reaction formulas involved: MgO + H2O → Mg(OH)2, Mg(OH)2 + 2CO2 → Mg(HCO3)2, 5Mg(HCO3)2 → 4MgCO3·Mg(OH)2·4H2O + 6CO2
