Description

Technical Field

[0002] Iron ore is a mineral aggregate containing iron elements or iron compounds that can be economically utilized. It can be used to extract single-element pig iron, steelmaking and many other purposes. Among them, iron tailings are waste after ore dressing and are the main component of industrial solid waste. The tailings can be utilized through sand making machines and sand making equipment. The solid waste discharged after the ore is ground and the useful components are selected. The discarding of tailings not only requires a large amount of land and causes great harm to the surrounding ecological environment, but also requires investment in their own processing and maintenance costs;
