Flotation tests were carried out in a 75 cm high plexiglas column with different cross sectional areas, ac , of 25 and 210.25 cm2 . the column was run rst with water and air until steady state was reached. pulp was fed into the column using a peristaltic.
With the depleting reserves of high-grade iron ore in the world, froth flotation has become increasingly important to process intermediate- and low-grade iron ore in an attempt to meet the rapidly growing demand on the international market. in over half a centurys practice in the iron ore industry, froth flotation has been established as an efficient method to remove impurities from iron.
Flotation test work was conducted on both samples and the optimum conditions presented in table 2. for the low throughput ore a flotation test work indicated that the majority of gold can be concentrated by concentrating the sulphide component in the ore to mass pulls of 9 to 10 wt, with gold recovery of 85 to.

Steps in the development and design of a flotation circuit . sample selection . the first stage of process design is a thoroughreview of the geology and mineralogy of the deposit. mining methods and mine plansschedules need to be assessed when selecting samples for the various phases of the flotation testwork program. ore selection must.
Thus the sulphide ore comes on the top with the froth and oil. the remaining gangue particles which did not dissolve in oil settle down. the foam is removed and taken for further processing. thus the minerals are separated by the froth -flotation process. this method is extensively utilized for copper sulphide, lead sulphide and zinc.
