Abstract:
A treatment mixture for eliminating acid generation by killing bacteria found in solid, inorganic sulfide bearing material, comprising:(a) a highly reactive alkaline component that generates an initial pH to kill the bacteria and neutralize a level of acidity of the solid, inorganic sulfide bearing material;(b) a lower reactive alkaline component that generates a lower maintenance pH to provide a long term alkaline environment in the solid, inorganic sulfide bearing material after the bacteria is eliminated; and(c) an adjuvant surfactant that acts as a dispersing agent for dispersing said highly reactive alkaline component and said lower reactive alkaline component to the solid, inorganic sulfide bearing material, wherein said adjuvant surfactant is less than about 0.1% of the total weight of the treatment mixture.
