What is Silicon Slag?

 

“Silicon Slag: The Golden Byproduct of Metallurgy!”


Silicon slag is a silicon-rich byproduct generated during the production of ferrosilicon and silicon metal, typically containing 45%-75% silicon. As a professional silicon slag manufacturer and supplier, Fengyang Metallurgical transforms this “waste” into a high-value resource, widely used in steelmaking, casting, and chemical industries.
