Industrial Silicon Slag
Basic Introduction To Silicon Slag Metal Alloy
1. Silicon slag (defective silicon) is a by-product of the production of metallic silicon.
2. The silicon content is 45% to 95%, and the rest is C, S, P, Al, SiO2, Fe, Ca, etc.
3. Silicon slag is much cheaper than pure metallic silicon and is widely used in industry.

The composition of silicon slag is a key factor affecting its performance and application. It is primarily composed of silicon, with varying amounts of iron, aluminum, calcium and trace impurities. Exact ingredients may vary depending on production processes and raw materials. Understanding this ingredient is crucial to optimize its use in different industrial settings.
How Is The Principle Of Ferro Silicon Slag Separation Implemented?
Extraction of industrial silicon from silicon slag. First, use a manual hammer to separate the light-colored slag and dark-colored slag in the silicon slag to increase the silicon content in the silicon slag, and then perform smelting separation to remove impurities in the molten silicon.

According to the properties of silicon slag, the smelting process includes manual separation, machine separation, adding raw materials, refining in the furnace, casting, crushing, dust removal, etc.
