Regime Design for Gold Ore Flotation by Air and Steam Mixture

Aug 11, 2021Stability of wettable films during flotation can be changed by their heating: inductance time reduces by a few orders of magnitude under higher temperatures [ 10 - 12 ]. In case of a sudden contact between cold water and bubble filled with hot steam, the particle-bubble contact zone can obtain >2200 kJ/kg in the form of the steam condensation heat.

By placing powdered ore in the mouth of a tobacco-pipe, closing the mouth with clay, and exposing the bowl to a fair heat, the mercury may be collected on a cool surface, held so that the fumes given off may be condensed. A gold coin or a piece of clean copper placed in the fumes will soon have a deposit of mercury on its surface.
