floatation question - Gold Refining Forum

Jul 17, 2010  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.

17 - Flotation of Gold Ores

Use of lime often results in the depression of native gold and gold-bearing sulphides. The optimum flotation pH ranges between 8.5 and 10.0. The type of frother also plays an important role in the flotation of native gold and gold-bearing sulphides. Glycol esters and cyclic alcohols (pine oil) can improve gold
