Three laboratory column experiments were performed to test the suitability of two different MgO-rich reagents for removal of Mn and Al from the out-?owing waters of Shilbottle passive treatment system (Northumberland, UK). The input water was doped with 100mg/L Zn in order to extrapolate results to waters in sulphide mining districts. One column was ?lled with a Dispersed Alkaline Substrate (DAS) containing 12.5% (v/v) causticmagnesia precipitator dust (CMPD) fromSpainmixedwithwood shavings, two columns were ?lled with DAS containing wood shavings and 12.5% or 25% (v/v), respectively, of dolomitic lime precipitator dust (DLPD) from Thrislington, UK. The two columns containing 12.5% of CMPD or DLPD completely removed the contaminants from the in?ow water during the ?rst 6 weeks of the experiment (mean removal of 88mg/L Al, 96mg/L Zn and 37mg/LMn), operating at an acidity load of 140 g acidity/m2 day. At thismoment, a substantial increase of theAl andMnwater concentration in the out-?owingwaters of Shilbottle occurred (430 g acidity/m2 day), leading to passivation of the reactive material and to the development of preferential ?ow paths within less than another 6 weeks, probably mainly due to Al precipitates. Al should be removed prior to MgO treatment. |
