  • Process for treating dust and fume produced by the basic oxygen steelmaking process
    Patent number: 4975115
    Abstract: A process for conditioning basic oxygen steelmaking process dust and fume containing heavy metals for disposal. A sufficient quantity of solidified basic oxygen steelmaking process slag particles are added to the dust and fume to produce a mixture having an alkalinity substantially greater than that of the dust and fume alone. The dust and slag mixture tests as non-hazardous when tested using the toxicity test procedures for heavy metals promulgated by the United States Environmental Protection Agency (EPA).

  • Method for beneficiating coal ore
    Patent number: 4376700
    Abstract: A new heavy liquid parting medium comprising an emulsion of water and a substantially water immiscible heavy parting liquid for use in beneficiating ores by gravity separations such as sink-float processes. The specific gravity of the emulsion parting medium can be adjusted by proportioning the relative amounts of water and the substantially water immiscible heavy liquid. As-mined coal is beneficiated using a water-trichlorofluoromethane emulsion as the parting medium in a sink-float separation process.
