The process of iron ore slag treatment
The process of iron ore slag treatment involves several stages that ultimately lead to the production of high-quality iron and steel. The first step is crushing, where large chunks of slag are broken down into smaller pieces using crushers or mills. This crushed material is then screened to remove any oversized particles.
The next stage in the process is grinding, which further reduces the size of the crushed slag particles. Grinding can be done using a ball mill or vertical roller mill, depending on the desired particle size distribution.

Once ground, the material undergoes magnetic separation to separate any metallic iron from non-metallic materials such as silica and alumina. This step uses powerful magnets to attract and separate out all magnetic particles.
The final stage in the process is smelting, where molten metal is produced from the refined slag through heating at high temperatures with carbon sources like coke or coal. The resulting molten metal can be used for many purposes including casting and forging operations.
This process ensures that valuable metals like iron are recovered from waste materials while reducing environmental impact by minimizing pollution and conserving resources.
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
