Method for Mitigating Acid Rock Drainage Potential through the Smoldering Combustion of Organic Materials

Methods are provided for the removal of sulfur and other ARD/AMD-generating materials through the smoldering combustion of an organic material. The methods comprise admixing an ARD/AMD-generating porous matrix material with an organic material to produce a mixture, exposing the mixture to an oxidant, and initiating a self-sustaining smoldering combustion of the mixture. Additional embodiments aggregate the organic material or ARD/AMD-generating porous matrix material or mixture thereof in an impoundment such as a reaction vessel, depression or matrix pile. Further embodiments utilize at least one heater to initiate combustion and at least one air supply port to supply oxidant to initiate and maintain combustion.
