उत्तर
Froth floatation process is used for the concentration of sulphide ores.
Explanation:
Froth flotation process is used for the concentration of sulphide ores such as zinc blende (ZnS) and copper pyrites (CuFeS2). In this method, the powdered ore is mixed with water and oil; sulphide particles stick to the froth and rise to the surface, while the gangue particles settle down.
