Acid drainage is a problem associated geographically and geologically with the mining industry and is due to production or sulfuric acid from sulfur-containing minerals. The data presented in the report demonstrate that it is possible to inhibit pyrite-oxidizing bacteria in high sulfur coal refuse with a concurrent reduction in acid drainage formed in the refuse. The most effective inhibitors studied are combinations of sodium lauryl sulfate (SLS) plus sodium benzoate (Bz), both of which are relatively nontoxic to higher organisms.
