Therefore, the proper beneficiation methods are need to improve the iron content of iron sand. In this research Kulon Progo iron sand was used as a raw materials because not only the reserves very abundant but also the new iron making plant will build here soon.
Abstract: Iron ore is an important raw material for manufacturing steel, while the grade of domestic iron ore is relatively low in China, thus it is difficult to concentrate. The low-grade iron ore with a total iron content of only 33.51% is innovatively upgraded by the magnetic-gravity combined beneficiation method.
Advantages of the kaolin dry beneficiation method: Wide range of applications: Dry beneficiation is suitable for kaolin ore with larger particles and can process coarser ore. No need for water source: Dry beneficiation only requires a few water resources, so ore treatment can be effectively carried out in areas where water resources are scarce, reducing the …

Although rare earth ores have complex mineralogy, high requirements for mineral processing technology, and difficult concentrate extraction. The beneficiation of rare earth ores is a complex process that requires a combination of physical and chemical methods. Valuable rare earth minerals can be separated from gangue minerals through processes such as gravity …
The main beneficiation methods of bauxite are washing, flotation, magnetic separation, chemical beneficiation, etc.The process of separating concentrates from bauxite ore is actually a process of removing gangue minerals and harmful impurities, and separating high-aluminum minerals and low-aluminum minerals to obtain concentrates with a high aluminum …
The purpose of kaolin beneficiation is to improve the whiteness of kaolin by removing harmful dyeing impurities such as iron, titanium and other organic matter, or to improve the quality of kaolin by removing sandy minerals such as quartz and feldspar. The kaolin purification processes currently used mainly include gravity separation, magnetic separation, …
