Absorption and surface-catalysed oxidation of iron occurs in an uncontrolled manner, causing extensive degradation of surface water quality, where ferrunginouis waters emerge from abandoned mines. The chemistry of these processes is well understood for lab systems using pure reagents and synthesised colloidal surfaces. These processes offer a potential, low-cost passive treatment method for minewaters at sites where active treatment or constructed wetlands are not physically or economically feasible. However, laboratory conditions are not representative of the size, complexity, duration and temporal variability or real ferrunginous discharges from abandoned mines. We therefore propose to investigate absorption and surface-catalysed oxidation of iron in test reactors installed at a representative field site. These reactors will contain various media with high specific surface area in order to accelerate the oxidation of iron and resulting accretion of ochre. The duration of contaminant release will be assessed by investigating the discharge rates and hydrochemistry of flooded workings that feed the reactors, provided a time-stream basis for cost-benefit analyses. Physico-chemically based mathematical modelling of iron removal, in the reactors will be used to quantify operation parameters and long-term cost-benefits for possible full-scale treatment.
