5 litres of 1x10^-2 Dodecylamin has been diluted to 1x10^-5M by adding accurate amount of water from the tap. To calculate required water amount mathematical equations given below : C1V1=C2V2 10^-2M x V1 =10^-5M x 1,000 mL V1 = 10^-5/10^-2 = 10^-3 M = 1,000 mL Here C1,C2; are the first and second concentrations of solution V1 and V2 ; are the required and current volumes. The impeller turned on and DDA, and tap water left to be mixed properly with water for 2 minutes. Approximately 150 grams of quartz added into the solution. Froth should not be stuck in the area where overflow speed is relatively lower and this was done by using a spatula. Attention paid to make froth collection almost waterless. The collection time intervals …show more content…

Cumulative recovery calculates a certain recovery amount of quartz at a specific time. It is impossible to recover all material.
