Hematite is a kind of weakly magnetic iron ore, and there are many beneficiation methods used. Traditional beneficiation methods include roasting magnetic separation, flotation and high intensity magnetic separation, but the index of a single process is poor. According to the characteristics of hematite beneficiation process, it can be divided into roasting magnetic separation process, flotation process, weak magnetic-strong magnetic separation process, strong magnetic flotation separation process and heavy magnetic-float combined process.
Multi-stage grinding and multi-stage flotation
In order to protect Hematite flake from damage, Hongji often adopts a multi-stage grinding selection process. The quality of the concentrate can meet the requirement after several regrinding and resorting.
Combined gravity separation and flotation process
For Hematite ores accompanied by heavy minerals, Hongji's combined gravity separation and flotation process can be used for sorting, that is, the heavy minerals are first separated by gravity separation, and then the heavy separation tailings (light minerals) are treated by flotation.
Flotation reagent
In the multi-stage flotation process, the commonly used foaming agents are No. 2 oil, No. 4 oil, ether alcohol, butyl ether oil, etc. The collector is kerosene, diesel oil, heavy oil, sulfonate, sfate, phenols, carboxylic acids, etc
Crushing process:
Due to the high hardness of iron ore, large jaw crusher is usually used for rough breaking. Before the crusher will add a vibrating feeder to evenly feed the jaw crusher mineral raw materials, while the raw ore screen is divided into +75mm and -75mm two grain grades. +75mm grade ore into the jaw crusher for rough breaking, -75mm grade ore into the cone crusher for crushing.
Grinding process:
Due to the large hardness of the ore and extremely fine dissemination particle size, it is difficult to achieve the required yield and monomer separation by using the ordinary one-stage grinding process, so the process adopts the two-stage grinding process. This not only reduces the ore slime caused by mineral overgrinding and the reduction of mill efficiency, but also increases the yield and achieves the required grinding fineness.
