This was followed by the addition of distilled water to about 60% of the cell volume before the required volumes of 1% solutions of the collector; SIPX (sodium isopropyl xanthate) and depressant were added. The additions of the reagents solution were done using small (2-5ml) barrel medical syringes. More water was added to the cell to about 90% cell volume (about 10mm below the froth overflow lip). pH was then adjusted to the required set value using either sulphuric acid or sodium hydroxide. Two drops of the frother were then added before conditioning with the air valve closed for 4 minutes at 750rpm agitation. Following conditioning, the air valve was opened to maximum to allow aeration. After 3 minutes the froth
