Instrumented Leach Column for the Study of Sulphide Oxidation in Waste Heaps

摘要

The construction, commissioning and first year of operation of a large scale, instrumented leach column are described. The column material was sulphidic mine overburden. Monitored parameters included matrix potential, temperature, redox potential, dissolved oxygen, pore space gas, water addition and drainage, together with pH, Cd, Cu, Fe, Ni, Zn, Cl exp - , F exp - , SO sub 42- and PO sub 43- in the effluent.
