galena ore is best concentrated by froth floatation method

Galena (ZnS) is a sulphide ore. Galena is best concentrated by froth floatation method. Froth floatation method is used to concentrate sulphide ores. Magnetite (Fe 3 O 4) is an ore of iron . Malachite (Cu 2 CO 3 (OH) 2) is an ore of copper and cassiterite (SnO 2) is an ore of tin. Hence, only galena contains sulphide ion. Chat

The mill grinding process is almost carried out in two consecutive stages: one is dry grinding (coarse grinding) and the other is wet grinding (fine grinding). The key grinding equipment are ball mills and rod mills, and the latter is now mostly used for wet grinding to finally produce fine and uniform ore products.
