North America: North America has relatively rich overseas reserves of Silicon Metal, mainly distributed in Canada and the United States. Canada has rich quartz deposits, of which silicon reserves account for more than 20% of the world's total reserves. The United States is also a country rich in quartz mineral resources, and its silicon reserves are among the highest in the world.
Australia: Australia is a world-renowned mineral resource power with rich silicon resources. Australia's silicon reserves are widely distributed, mainly in quartz deposits, with considerable reserves.
South Africa: South Africa is one of the countries with the richest silicon mineral resources in Africa. Its silicon reserves are mainly distributed in the silicon mining area in central South Africa, and the quality of the deposits is relatively high. Brazil: Brazil's silicon reserves are mainly distributed in southern Brazil, especially in Sao Paulo, Minas Gerais and Paraná, which are regions with relatively rich silicon resources.
Norway: Norway is one of the countries in Northern Europe with rich silicon mineral resources. Its silicon reserves are mainly distributed in the silicon mining area in western Norway. It is one of the world's famous silicon resource producing areas.
In addition to the above-mentioned regions, other countries and regions such as India, Russia, South America and other regions also have a certain amount of overseas metal silicon reserves.
In general, the total amount of overseas metal silicon reserves is quite considerable, providing a rich resource base for the development of the global metal silicon industry. With the continuous advancement of technology and the continuous advancement of resource mining, overseas metal silicon reserves are expected to increase further.
