The effect of agitation in the cyanidation of gold ores: M34-20/105E-PDF

“The effect of agitation on the leaching rate of gold from ore of the Lamaque Mining Company Limited was investigated. Leaching-solution velocities, relative to the ore particles, of from 25 to 150 cm per minute were studied by passing the solution at various flow rates through a static bed of the ground ore. The lowest velocity investigated was that occurring in an air-lift agitator. Along with the static-bed tests, other tests were made in which the slurry was stirred vigorously with a high-speed stirrer. These stirred tests were done to simulate high-speed agitation and were presumed to result in much higher velocities of solution relative to the ore than those used in the static-bed tests. It was concluded that the rate of cyanide leaching of gold from this ore was independent of the solution velocity relative to the ore particles in the range of velocities studied. The practical significance of this is that the gold leaching rate from ore similar to that used in this work would be independent of the type of reactor used for leaching"--Abstract, p. i.
