Light burned dolomite is mainly used in steelmaking to improve the fluidity of steel slag and as a slagging agent; this dataset includes the main raw materials, auxiliary materials, energy, atmospheric emissions, and wastes in the production process, but it does not cover the production equipment manufacturing, plant construction, or other infrastructures within its boundaries; data inventory is formed by aggregating data from multiple sources; the production process of light burned dolomite includes feeding, vibrating feeding, mixing, laying material, calcination, discharging, and screening, and it usually involves calcination at high temperatures (800°C to 1000°C). During this process, some of the carbon dioxide in dolomite is released, converting it into active calcium oxide.
