INTRODUCTION

Metal silicon slag is a common industrial waste, mainly composed of elements such as silicon, iron, aluminum, and calcium. Among them, silicon is the main component of metal silicon slag, accounting for the majority of its total mass.

Silicon is a non-metallic element with high chemical activity and thermal stability. In metal silicon slag, the silicon content is usually above 50%, so metal silicon slag has a high silicon content. The main use of silicon is to manufacture high-tech products such as semiconductor materials and solar panels, so metal silicon slag has also become an important raw material.
