Mineral Processing: To recover valuable minerals from low-grade ores or ore bodies with complicated mineral compositions, froth flotation is a commonly used technique in mineral processing plants. Phosphorus, potash, and graphite are just a few of the industrial minerals that are beneficiated using it.

depends upon the dispersion of the mineral of interest. Crushing is done mostly using mechanical crushers. Crushed materials produced are usually below 10-14 mm (0.4 to 0.6 inch dia) so as to directly feed into the grinding milling machine. To get this grain size, crushing is done in stages. First few crushing is
