  • Waste Dump Leaching Copper - Metallurgist & Mineral .

    Ore bed permeability became drastically diminished because salts precipitated in the ore fines, and portions of the ore were denied access to necessary ferric ions. Leach liquor circulation rate decreased from 835 l/m²/day (20.6 gal/ft²/day) to only 33 l/m²/day (0.82 gal/ ft²/day) by the 461st day of leaching.

    In iron formations, the amount of iron has been concentrated by weathering and leaching of non-iron minerals, such that we only use the term "iron formation" for rocks that contain >50% iron. The ore (iron) is concentrated by downward percolating water, and occurs in places where downward flowing waters are guided and converge, such as along a slanting layer of .
