Heap leaching

Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and reseparate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the

Uranium ore is crushed and formed into a slurry. The slurry is pumped into a leaching tank and classified by a sparge tube projecting water at teeter velocity at the bottom of the ore bed. Thereafter, a second ore bed is pumped by the slurry into the tank and the second bed classified. This is repeated until there are four or five ore beds in the tank.

Nov 01, 20060183;32;An additional consideration for slurry systems is restarting agitation after a power failure. Agitators are often unable to resuspend the solids once they have settled. Most pumps are designed for light slurry loads and can t handle the settled solids, usually due to the high viscosity. Sparging with a liquid is the best solution for agitation.

Process Engineering Avoid trouble with slurries
  • Maintaining a uniform suspension in a crystallizer or a slurry tank is impossible, no matter what the theory will tell you. Although colloids and very fine particles can be suspended with appropriate agitation, only a portion of the large particles will be suspended. Agitators should be selected to provide enough suspension to keep most of the solids off the bottom of the vessel. This is very important when the solids are cohesive. In addition to agitator selection, you must consider tank design, baffle selection, and slurrLive Chat
