Outline of SAMIs Magnesium Smelting Technology

SAMI is one of the earlier and largest companies in China engaged in engineering design and technological development (R&D) in the magnesium smelting industry. We have and hold electrolysis/reduction process and Thermal/Pidgeon process to produce metallic magnesium, as well as possess the suspension calcinations technology to produce light-burned magnesium oxide, and high-grade high-purity magnesium sand.

            

SAMI has created and achieved the "First" performance in China

ØThe first electrolytic magnesium production line - Fushun Aluminum Plant Magnesium Workshop;

ØThe first production line using magnesium electrolysis cells without partitions - Fushun Titanium Industry Co., Ltd.;

ØThe first largest 100kt/a electrolytic magnesium plant in terms of production capacity- Magnesium Plant of Qinghai Salt Lake Magnesium Industry Co., Ltd.;

ØThe first industrial scale thermal magnesium plant - Hubei Tangshan Magnesium Plant.

In 2021, in accordance with the requirements of Chalco, SAMI established the Magnesium Resource Comprehensive Utilization Research Center, not only focusing on technology research on magnesium, but also actively extending to the R&D field of comprehensive utilization of resources such as titanium and calcium, so as to positively building of excellent composite technology innovation team with professional talents working on magnesium, titanium, calcium and other smelting technology.

At present, there are over 10 engineers on magnesium R&D, more than 30 engineers on engineering industrialization, and 10-odd external-introduced experts. We have established a composite technology innovation team featured by multiple research directions, strong scientific research capabilities, precise process technology, and rich engineering experience.

Main Technologies and Indicators of SAMI:

lSAMI has Φ The 600 vertical-tank reduction furnace technology for thermal/ Pidgeon Process, achieving the following advanced indicators:
