Pyritic gold ore is processed using the bulk flotation method as the first step for further treatment. The daily tonnage is 5,500 tonnes/day (on a dry basis). The average density of the ore is 2.77. After grinding, the ore is slurried with water to a density of 40% solids (by wt.) and pumped to a conditioning tank where reagents are added. The tank is cylindrical with an internal diameter of 3.5m and height of 5.0m. The active volume is set at 40m3 with a level controller. The conditioned slurry is then sent to flotation circuits for gold concentrate production and gangue rejection. This question is not concerned with that part (i.e., shaded area). a) Determine the volumetric flowrate of the 40% slurry into the conditioning tank in m3/ minute. b) The active slurry volume used in the tank is 40m3 through a level controller to avoid overflowing. Given the tank dimensions noted above, determine how full the tank will be with the slurry in \% under steady operating conditions. c) Determine the period the 40% slurry is expected to spend in the tank in its journey to the flotation stage (i.e., the residence time or conditioning time) in minutes for adequate reagentizing the target particles. For simplicity, ignore: i) the volume occupied by the impeller system in the tank and ii) the flowrate of reagents as additional input to the tank ( 35 marks)
