In froth flotation which is also used to concentrate metal ores for copper lead zinc and other metals in modern practice the finely crushed ore is mixed with oil and water in large tanks The gold particles are better wetted by the oil while the gangue particles are better wetted by the water air is blown into the tank to produce a froth of oil and the gold particlthe need to crush the ore bearing rock this makes the ore more manageable and increases the exposed surface area for the chemical reaction to have a higher rate separation of the finely divided gold metal in the ore by dissolving in sodium cyanide oxygen

1/11/ 32 Thus in commercial practice gold cyanide adsorption onto the ore should be enhanced by soluble calcium in the ore and the calcium as Ca0 added for pH control If the effect of Ca 2 on gold adsorption is simply an ionic strength effect then the aurocyanide complex should adsorb to the same extent at the same ionic strength irrespective of the added cationHow to Use Bleach on Gold Ore to Remove Gold Sciencing Apr 24 Pour the acid and bleach mixture into the stone bowl with the ore grains and stir Allow four hours for the gold to dissolve stirring every 20 minut The chlorine reacts with the gold inside the
