Although the rich resources of iron ore, but mostly lean ore, in addition to very few outside the high-grade ore, accounting for about 98% of the reserves for the lean ore, iron content of 20-40%, with an average of 30%. It must be processed by mineral processing, and the iron content after selection can reach more than 60%. The process flow of the iron ore beneficiation equipment production line is simple, mainly two steps of mixing and mixing. Careful analysis of the iron ore beneficiation process, the main components of the incoming raw materials are iron oxides (mainly Fe203, Fe304). The main principle of the production process is to remove impurities from the iron slag and purify the raw materials to meet the relevant production. Material requirements. It is important to choose a fine iron ore. How to deal with the slag ore after mineral processing?

The iron slag produced by the iron ore dressing equipment production line is treated by sulfuric acid, starch and ferric chloride. Among them, sulfuric acid is used as a regulator to adjust the pH of the solution. The operating control range of pH is moderately acidic 3~4 as rapid setting. The pH of the agent should not be lower than 2, otherwise the iron is dissolved and the material is lost. In this pH operating environment, impurities condense into a lighter-weight solid, and ferric chloride acts as an activator, which plays a leading role in the reaction. The reaction process of iron slag and auxiliary materials is achieved by stirring, and the concentrate and tail after stirring. The slag passes through the chute, and according to the respective densities, the concentrate powder with higher density is the finished product, and the remaining impurities are further precipitated through the sedimentation tank, which is the tail slag, and the water in the upper layer of the sedimentation tank is recycled.
