Dry & wet separation are the two main Kaolin mining process of Xinhai. Dry separation process is used to process Kaolin ore with higher white degree and lower sand and gravel content, this process characterized by easy operation and saving cost. Kaolin raw ore being crushed in Kaolin crusher, then the Kaolin concentrate can be get after being grinded in raymond mill. Wet Kaolin mining process is used to process complex Kaolin mine. Xinhai wet separation process applying high gradient magnetic separation(HGMS), froth flotation and selective flocculant to make full use of Kaolin mine resources.
Kaolin wet process is suitable for Kaolin mine with soft texture and high brightness.
HGMS is used to process kaolin mine with staining impurities such as hematite, which can efficiently remove impurities so as to improve brightness and quality of the kaolin concentrate.
Flotation separation is used to remove titanium ore that is in the form of silicas. Applying calcite and silica sand as carrier to increase the ion kinetic energy. Flotation cell is the main kaoling mining machines of this part.
Applying polymer flocculatant as kaolin mining selective flocculant. kaolin mine will sink to the bottom while titanium ore suspend in the upper showing red brown, thus we can use magnetic separation to process kaolin mine.
Bringing mine owners LARGE profits, Xinhai has set up over 50+ gold CIL plants worldwide and build a reputation in the field of mineral processing technology since 1997. Xinhai provides Whole Line Plant & Design Personnel Training, helping mine owners with Equipment Procurement and Construction from ore to pure gold. About our EPC Service, check out EPC Service Here.
