Study on a New Technology of Separating Seabeach Placer with Mixed Collectors

A new flotation method is introduced for separating zircon from rutile and other Ti-bearing minerals at normal temperature, using a mixture of cationic and anionic collectors without any acid, alkali or fluoride as regulators. By combining the method with gravity concentration and magnetic separation to process the seabeach placer, the technological flowsheet can be simplified and the pollution of environment and the corrosion of acids, alkalis and fluorides on equipment can be removed.
