The solution is then collected and processed. The Beverley uranium deposit is an example of in-situ leaching and also Trojan Mine in Zimbabwe. Heap leaching
In heap leaching processes, crushed (and sometimes agglomerated) ore is piled in a heap which is lined with an impervious layer. Leach solution is sprayed over the top of the heap, and allowed to percolate downward through the heap. The heap design usually incorporates collection sumps, which allow the "pregnant" leach solution (i.e. solution with dissolved valuable metals) to be pumped for further processing. An example is gold cyanidation, where pulverized ores are extracted with a solution of sodium cyanide, which, in the presence of air, dissolves the gold, leaving behind the nonprecious residue. Vat leaching
Vat leaching involves contacting material, which has usually undergone size reduction and classification, with leach solution in large vats. Tank leaching
Stirred tank, also called agitation leaching, involves contacting material, which has usually undergone size reduction and classification, with leach solution in agitated tanks. The agitation can enhance reaction kinetics by enhancing mass transfer. Tanks are often configured as reactors in series. Autoclave leaching
Autoclave reactors are used for reactions at higher temperatures, which can enhance the rate of the reaction. Similarly,  autoclaves enable the use of gaseous reagents in the system. Solution concentration and purification
After leaching, the leach liquor must normally undergo concentration of the metal ions that are to be recovered. Additionally, undesirable metal ions sometimes require removal.
Eosinopenia is a form of agranulocytosis where the number of eosinophil granulocytes is lower than expected. Leukocytosis with eosinopenia can be a predictor of bacterial infection. It can be induced by stress reactions, Cushings syndrome, or the use of steroids. Pathological causes include burns and acute infections. See also
