Froth flotation is an important and versatile separation technique in the mineral processing industry for recovering valuable minerals from mining ores (Aghazadeh et al., 2015).Froth flotation is a physico-chemical separation process based on the differences between the surface wettability of valuable and valueless components (Wills and Finch, 2015).

Ores are solid material from which a pure metal can be obtained. The process of removal of unwanted material from the ore is known as concentration or dressing or benefaction of ores. It involves several steps. The separation of required material from the ore is dependent on the differences in physical properties of the compound of the metal present and that of the gangue.
