leaching as a process of decomposition of rock

  • Leaching geochemistry of soil Britannica.com

    the forest zone is the leaching process. The forest leaves and needles that fall, together with dead remains of the sparse grass cover, are subjected to decomposition by organic acids in the litter of the forest floor.

However, sulphide ores do not allow the recovery of metal by direct chemical leaching (Hiskey and Wadsworth, 1975; Dutrizac, 1989), due to their low solubility in most leaching reagents. In such cases, ore must be pre treated in order to release the desired metals physically and to make the ore amenable to leaching
