Magnesium Production Line refers to a complete set of industrial equipment and devices that transform magnesium-containing raw materials (such as dolomite, magnesite, seawater, salt lake brine, etc.) into pure magnesium metal through a series of physical and chemical processes. Our company's magnesium production line utilizes the Pidgeon process with dolomite as the raw material. We can provide magnesium production plant design, equipment supply, consultation and technical service.

Pidgeon process is applied in the company’s Mg smelting technology in the process of magenesium production line. Henan Zhengzhou Mining Machinery Co., Ltd began to manufacture equipments for Mg smelting industry from 1988, and focused on the technology upgrading and utilization. During 2003-2005, the company started to use vertical pre-heater for the calcination of dolomite. This kind of new pre-heater saves fuel by 40% and increases the output by 30%.

The Pidgeon Process is a silicothermic reduction method and is currently the primary method for producing metal magnesium globally, especially in China (accounting for over 80% of global magnesium production). Its core principle is: under high temperature and vacuum conditions, use ferrosilicon (FeSi75, meaning a silicon-iron alloy containing 75% silicon) as a reducing agent to reduce the magnesium oxide (MgO) in calcined dolomite (CaO·MgO) into metallic magnesium vapor, which is then condensed to obtain crystalline magnesium (commonly known as "crude magnesium"), and finally refined to produce pure magnesium ingots.

✔ Pidgeon Process Project Cases
We have done many successful projects in both China and overseas countries. POSCO is world class iron and steel supplier in Korea. In the year 2011, we have signed an annual output of 100000 tons of magnesium metal project with the world iron and steel giant Korean Pohang iron. The whole set of equipment for their magnesium plant are supplied by us.
