Understanding Leachate Analysis AWE International

Some methods clearly define the critical parameters in each stage whereas others provide only general instructions. A good way to grasp the potential differences in leaching methods is to compare and contrast the European Standard methods BS EN 12457 with the USEPA Toxicity Characteristic Leaching Procedure (TCLP) method.

Leaching reagents in the form of cyanide and an oxidant such as air or oxygen are added after thickening. Leaching takes place in a series of agitated leach reactors or pachucas. Before leaching the pH of the pulp is normally adjusted to a value of around 9.5–11 to ensure minimum loss of cyanide as hydrogen cyanide.
