this ore is the most important source of iodine in the world and is processed mainly by heap leaching using water as a leaching agent. heap leaching of caliche ore is carried out by the stacking of rom (run-of-mine) material where the particle size distribution covers a wide range from a few millimeters up to several decimeters even
heap leaching relies on a leaching agent moving through a bed of heaped ore to extract the metallic components: crushed ore is stacked on a leaching pad and irrigated with the leaching agent. the leaching agent chemically reacts with the metal in the ore to dissolve the copper into the solution as it percolates through the heap.
over-head sprinkler systems for heap leaching achieve full coverage maintaining uniform ore profile leaching. better control can be achieved using sprinklers with a low precipitation rate to match the heap and crushed rock permeability. low precipitation can maintain better aeration conditions that can help when bio-leaching is involved.
silver heap leaching 2000 tpd. a silver agglomeration-heap leaching operation is located near tombstone ariz. two types of materials are mined: old waste material that was used for mine backfill and virgin ore adjacent to the waste material. the waste material is mined with front-end loaders to expose the virgin ore.
in-situ leaching (isl) also called in-situ recovery (isr) or solution mining is a mining process used to recover minerals such as copper and uranium through boreholes drilled into a deposit in situ. in situ leach works by artificially dissolving minerals occurring naturally in a solid state.
