Flotation process can achieve ideal separation effect, and separately recover low-grade ore then enrich multiple high-grade concentrates. Different ore properties means different flotation process. According to the dissemination characteristics of metal minerals, Xinhai has determined four kinds of flotation processes.

Mining coal . Coal miners use large machines to remove coal from the earth. Many U.S. coal deposits, called coal beds or seams, are near the earth's surface, while others are deep underground.Modern mining methods allow coal miners to easily reach most of the nation's coal reserves and to produce about three times more coal in one hour than in 1978.

Lithium Extraction and Processing. The process of extracting lithium from brine deposits is: Lithium-bearing groundwater, typically carrying 200-1,400 milligrams per liter (mg/L) Li, is brought to the surface to evaporate in large basins. A concentrate of 1-2% Li is obtained after a few months to a year, depending on climate.

This is relatively easy to process and separate. By contrast, volcanogenic-massive-sulphide ore - or VMS - is made up of lead, zinc, copper, gold, and silver.
