“…Organic acids promoted the transport of H + in the hydration paste and promoted the dissolution of Ca 2 SiO 4 . Li Jia et al [134] modified magnesium slag by adding BaO, B 2 O 3 and P 2 O 5 during the hydration and quenching process of magnesium slag. BaO, B 2 O 3 and P 2 O 5 inhibited the nucleation of γ-C 2 S, prevented the crystal phase transformation of β-C 2 S during cooling, and increased the content of highly active β-C 2 S. The highly active β-C 2 S is formed by hydration [C=S=H], which enhanced the physical adsorption capacity of magnesium slag.…”

Under the policy of low carbon energy saving, higher requirements are put forward for magnesium smelting. As the mainstream magnesium smelting process, the Pidgeon process has the disadvantages of a long production cycle, high energy consumption and high carbon emission, which makes it difficult to meet the requirements of green environmental protection. This paper reviews the research progress on different magnesium smelting processes and further analyzes their energy consumption and carbon emissions. It is concluded that the standard coal required for the production of tons of magnesium using the relative vacuum continuous magnesium refining process is reduced by more than 1.5 t, the carbon emission is reduced by more than 10 t and the reduction cycle is shortened by more than 9.5 h. The process has the advantages of being clean, efficient and low-carbon, which provides a new way for the development of the magnesium industry.
