  • Process for rendering waste from electric furnace production of phosphorus non-hazardous
    Patent number: 6444130
    Abstract: The invention is a process for treating waste slurry generated in the electric furnace production of phosphorus in which a superatmospheric reactor is operated at an elevated temperature to destroy cyanides, phosphorus, and phosphides present in the waste. The process transforms wastes from the phosphorus electric furnace process into non-hazardous solid, liquid, and gaseous wastes that meet environmental regulatory requirements regarding solids for phosphorous, cyanide, phosphine and cyanide flux, and TCLP metals, and regarding the filtrate for UTS metals.

  • Treatment of aqueous phosphorus wastes
    Patent number: 5368741
    Abstract: Aqueous phosphorus wastes from the electric furnace production of phosphors and containing heavy metal bearing particulates are treated with lime whereby the phosphorus is converted into useful phosphorus compounds and the heavy metals rendered sufficiently non-leachable to permit their release into the environment. The treatment is conducted above about 60.degree. C. at a pH of between about 11.0 to 12.5.
