In summary, the majority of feldspar deposit are related to how the final separation of feldspar and quartz feldspar flotation method. In fact, since 1939, has been the main means to obtain feldspar pegmatite granite, granite and quartz sand deposit in half in the capital. The flotation method in the United States, Japan, Italy, Finland, the Soviet Union, Germany I IT West brother and other countries are very popular. The yield of 85 and above is feldspar obtained by flotation method. The flotation separation of feldspar and rock after fluoride flotation and fluorine free flotation of two methods, the flotation technology has made new progress.
In 1939, the United States Homola (O Meara) proposed by HF as activating agent, fatty amine as collector of feldspar flotation method agent, although the law is a good separation effect, and has been widely used in industrial production in a long period of time, but because HF belongs to toxic agents, to live easily polluted water Gong, and feldspar concentrates also contain fluorine ingredients, add on processing cost, people has been devoted to the study of.70 in the middle of fluorine free flotation method, feldspar fluoride free flotation in on the success of Japan and the United States and won the application in industrial production. The characteristics of the method is replaced with sulfuric acid or hydrofluoric acid hydrochloric acid, with high aliphatic amine and sodium petroleum sulfonate as the flotation separation of feldspar from quartz in mixed collector. At present. "Japan has many beneficiation plant using this method. In recent years in China put forward without fluorine New technology of acid flotation of feldspar and quartz. Its characteristic is in the pulp pH value close to natural conditions, collectors by using anion cation collector (petroleum sulfonate and n-alkyitrimthylene two amine flotation of feldspar). Among the continuous expanding test to obtain good results. Quartz concentrate can be used as raw material for high quality glass. Feldspar concentrates can be used as ceramic raw materials.
