Unformatted text preview: 3) Process water after flotation is usually recovered and recycled back into the process. Assume that 5,000 m 3 of recycled water is available for flotation, and it turns out that this water still contains 5 mg/dm 3 of dissolved frother. The idea is to mix this recycled water with a fresh batch of dry ore to produce a flotation pulp with a solids content of 25% (wt). a) Is the amount of dissolved frother in recycled water sufficient to achieve a frother dosage of at least 12 g/t ? b) The frother is a pure alcohol with a density of 0.8 g/cm 3 . What volume of pure frother would be required to increase the dosage to 25 g/t from the value obtained under a) ?...
