Abstract: Gravity separation is an important method to wolframite separation, but its effect on the microgran - ular mineral separation is poor. Flotation is the best way to ultrafine mineral separation. In recent years, the research of ultrafine wolframite in China has achieved certain progress, but there are many problems in respect of actual production yet. Based on the characteristics of the ultrafine wolframite, this paper introduces the new technology in the flotation of ultrafine wolframite, flotation reagents, etc., by discussing their characteristics and applicability. The theoretical researches and application cases of ultrafine wolframite are reviewed and can be used for reference in the rrelavent manufacturing process of the tungsten mines.
