Tracing magnesium flows in China: A dynamic material flow analysis

Comparison of Thermal Deformation Behavior and Characteristics of Mg-Gd-Y-Zn Alloys with and without Bulk LPSO Phase

“…Magnesium alloy is regarded as the most promising structural metal material of the 21st century due to its benefits of abundant reserves, low density, high specific strength and stiffness, and simple recycling, and has been promptly gaining attention in a variety of fields, including aerospace, automotive, and weapons [1][2][3]. However, magnesium alloys usually feature restricted slip systems activated at room temperature because of the close-packed hexagonal structure, which results in low room temperature deformation capacity, making for a generally lower absolute strength and plasticity compared with aluminum and steel alloys [4,5].…”

Exergy Analysis and Modeling of Pilot-Scale Pyrolysis for Magnesium Oxide Preparation from Salt Lake Bischofite Industrial Waste

“…Due to rapid urbanization and industrialization in developing countries, magnesium (MgO) remains in high demand globally for applications in the iron and steel industry, cement manufacturing, and nonferrous metallurgy. , According to data from the United States Geological Survey (USGS), China is responsible for 90.00% of the global production of magnesium refractories . The main raw material for manufacturing magnesium refractories is magnesite, which accounts for 76.90% of the overall output . The production of magnesium refractories from magnesite results in the release of carbon dioxide from the combustion of fuels and the decomposition of magnesite .…”

“…Within the salt lake industry, potassium chloride (KCl) extraction generates industrial byproducts in evaporation ponds, including bischofite. , Generally, bischofite (MgCl 2 ·6H 2 O) is a magnesium chloride mineral with crystallization water . However, the accumulation of large quantities of bischofite waste threatens the sustainable development and ecological environment of the salt lake industry. , Unfortunately, the utilization rate of bischofite remains low, with less than 1% of the total waste being effectively utilized . Statistical data from 2019 in China indicate that the production of potassium chloride was 804,000 tons, while solid waste bischofite exceeded an annual volume of 80 million tons .…”

“…3 The main raw material for manufacturing magnesium refractories is magnesite, which accounts for 76.90% of the overall output. 4 The production of magnesium refractories from magnesite results in the release of carbon dioxide from the combustion of fuels and the decomposition of magnesite. 1 Consequently, China, the global leader in the magnesium metallurgical market, must assume the environmental responsibilities associated with magnesium mining, manufacturing, and smelting.…”
