Frequently Asked Questions (FAQs)

Frequently Asked Questions About Machining Magnesium Factories in China

What is the primary method used for magnesium production in China?

In China, the majority of magnesium is produced using the Pidgeon process, a method invented in the 1940s in Canada. This process involves reducing magnesium oxide with ferrosilicon in a retort, and it is highly energy-intensive. The Pidgeon process is dominant in provinces like Shanxi, Ningxia, and Henan, where high-grade dolomite ore is readily available.

Why is China the largest producer of magnesium globally?

China is the largest producer of magnesium due to several factors. It has abundant resources of high-grade dolomite ore, which is the primary raw material for magnesium production. Additionally, regions like Fugu county in Shaanxi province offer cheap power from waste gas emissions of neighboring semi-coke smelters, making production costs significantly lower. This combination of resources and energy efficiency allows China to produce magnesium at competitive prices.

What are the environmental impacts of magnesium production in China?

Magnesium production in China, particularly using the Pidgeon process, has significant environmental implications. The process is energy-intensive and contributes to greenhouse gas emissions. A life cycle study has shown that the production of magnesium in China has a substantial global warming impact, mainly due to the high energy consumption and coal usage during the production process.

Where are the main magnesium-producing regions in China?

The main magnesium-producing regions in China are Shanxi, Ningxia, and Henan provinces. Shanxi alone has 72 magnesium plants with a production capacity of 61,500 tons per annum. These regions are favored due to their rich deposits of high-grade dolomite ore and access to cheap energy sources.

How does China’s magnesium production affect global trade?

China’s dominance in magnesium production significantly influences global trade. China exports large quantities of magnesium to countries like Canada, India, Turkey, Japan, and South Korea. In 2022, China exported $2.46 billion worth of magnesium, making it the world’s largest exporter of this metal. This extensive export activity contributes to China’s positive trade balance in the magnesium sector.
