Because different types of lithium ores have different properties, and the low content of lithium oxide in the minerals is low, and the mineral composition is different, the beneficiation processes of lithium ore are also different. At present, the main lithium ore beneficiation methods include：flotation separation method, magnetic separation method, heavy medium beneficiation method and combined beneficiation method.

Quartz sand purification is removal of a small amount of impurities and the high difficulty separation technique to obtain refined quartz sand or high purity quartz sand. The purification technologies of quartz sand at home and abroad are washing, classifying and desliming, scrubbing, magnetic separation, flotation, acid leaching, microbial leaching, etc.

Nickel ore can be divided into copper sulfide nickel ore and nickel oxide ore. Flotation is the main beneficiation method when processing copper sulfide nickel ore, and magnetic separating and gravity separating are the commonly auxiliary methods.

According to different ore properties of phosphate, Xinhai designs many processes for it such as flotation, gravity separation, chemical leaching, combined dressing, photoelectric sorting, etc. Flotation is widely used in phosphate including direct flotation, reverse flotation, reverse flotation and flotation, and double-reverse flotation process.
