10 Problems in the Flotation Process and Troubleshooting
Too coarse ore particles (greater than 0.1mm) and very fine ore particles (less than 0.006mm) do not float well, and the recovery rate is low.. In the flotation of coarse particles, due to the larger weight, the shedding force of the ore particles increases.So, you need: (1) Use a sufficient amount of the most effective collector.

floatation question | Gold Refining & Metal Extraction Forum
In the early days of flotation, coal tar or pine oil (turpentine) were used in very small amounts per ton of ore to float gold. The finely ground ore was mixed in tanks with paddles designed to suck in air, or compressed air was piped into the bottom of the tank. The gold would attach itself to a rising air bubble and float.
