To process pyrotechnical material contg. black powder, it is rendered harmless and the propellant contg. black powder is taken up by water. The remainder of the material is sepd. and transferred to further processing. The propellant element is formed into a sludge with water for the solids to precipitate and the potassium nitrate residue to be absorbed. The process is repeated until the potassium nitrate content in the precipitate is less than 4%. The final precipitate is recycled and/or disposed of. Also claimed is an application for the potassium nitrate solution to decontaminate earth soiled with hydrocarbons, where the solution has a potassium nitrate content of 1-2 wt.%. USE/ADVANTAGE - The method is for the disposal of explosive material, contg. black powder, which has exceeded its shelf life. The process is simple, and recovers useful material for recycling.
