Leaching (metallurgy)

Leaching is a process widely used in extractive metallurgy where ore is treated with chemicals to convert the valuable metals within into soluble salts while the impurity remains insoluble. These can then be washed out and processed to give the pure metal; the materials left over are commonly known as tailings. Compared to pyrometallurgy leaching is easier to perform, requires less energy and is potentially less harmful as no gaseous pollutionoccurs. Drawbacks of leaching include its lower efficiency and the often

01/09/2020 The leaching of the iron ore tailing (IOT) carried out with a 10.8 mol L-1 of HCl at a temperature of 80° for 120 min resulted in a 94% solubilization efficiency of iron. The leachate presented 11% Fe in its composition and a low concentration of contaminants, which enabled the liquor to be used as a coagulant. The water treatment test showed the effectiveness of the FC/IOT reagent in the

TREATMENT OF CYANIDE HEAP LEACHES AND TAILINGS

Cyanidation includes both heap leaching and tank leaching. Spent ore or tailings containing residual amounts of cyanide are generated as wastes. These wastes are typically treated to neutralize or destroy cyanide prior to final closure.
