Flotation of Nickel-Copper Sulphide Ore: Optimisation of

2020-1-8  All the flotation test-work was done using the Denver laboratory machine with a 1.5l stainless steel flotation cell. The required mass of nickel-copper sulphide ore material ground to 70% passing 75 µm was weighed and placed in the flotation cell. 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 was allowed to overflow and the float

Effects of flotation operational parameters on froth

2021-2-10  Froth stability plays an important role in determining selectivity and recovery in flotation (Farrokhpay, 2011). It should be noted that froth with very high stability is not desirable because in addition to recovering the particles attached to the bubbles, it creates favourable conditions for entrainment (Zheng, Franzidis, and Johnson, 2006).
