The crystals of the caustic potash were used to synthesize potassium ethylxanthate (KEX) at optimum temperature of about 45°C. The flotation tests carried out showed that over 200% recovery was achieved during the concentration of galena mineral. Physical characterisation and ultraviolet spectroscopic analysis showed the presence of an alkali xanthate as the collector specie. ER -
