Useful Material Silicon Slag

Silicon slag, also known as silica waste slag, is the remaining part of silicon ore during the refining process and mainly contains a certain amount of silicon componentsBecause it contains a large amount of silicon, silica slag is regarded as one of the metallurgical materials purchased in large quantities by production enterprises, and has irreplaceable advantagesThere are many types of silica slag, which can be roughly divided into industrial silica slag, solar silica slag, semiconductor silica slag, etc.

1.Although most people may think that silicon slag is a useless alloy slag, in fact, silica slag has important applications in the steelmaking and casting industry, such as recrystallization, purification, etc., and can also be used as a steelmaking deoxidizerBecause polysilicon is relatively scarce in the current market, the price is expensive, and the silicon slag itself also contains great utilization value, so in the metallurgical industry, silicon slag is widely used as a materialIn addition, the process of recovering zirconium from zirconium-containing silica slag includes multiple steps, such as acidizing process, rinsing, filter pressing, etc., and finally obtaining acid silica slag and zirconium oxychloride mother liquorThe methods of preparing silica from waste silica slag of zirconium oxychloride mainly include alkali method and neutralization method, and valuable products can be extracted from silica slag through a specific processThese processes not only improve resource utilization, but also contribute to environmental protection and sustainable development.
