  • Publication number: 20060207289
    Abstract: A formulation (process) and production of a hard, tough material of ferro matasilicate lattice crystals and dispersed crystals of lead, ferro, copper, zinc, and antimony spinels in glassy matrix. Variation of the degree of crystallinity and the ratio of crystals control the properties of the resultant product. These are controlled though formulation, processing conditions and residence times and through control of the heat history from tap out of the kiln to the final bagged product. Production of the product utilizes copper slag which is waste from the production and refining of copper. The component materials include: calcium, copper, arsenic, antimony, zinc, lead, and iron at very consistent levels of various oxide forms. The resultant process converts hazardous waste, such as copper slag (KO61), to a non-hazardous (TCLO criteria) product that contains no free silica. Product performance can be tailored to meet the needs of the loose grain abrasive market as speed and profile test have demonstrated.

  • Publication number: 20040177664
    Abstract: The subject of this patent application is the formulation and production of an organic based agricultural soil fertilizer/conditioner. The principal product meets the standards of the U.S. Department of Agriculture as 2-2-2, 10-10-10, or other similar mix of fertilizer for land application. The organic based material is municipal sludge from wastewater treatment plants. Sludge material meeting the United States Environmental Protection Agency (USEPA) standards is used. These materials are treated with chemicals and/or an electron beam to render pathogens harmless in the waste material. Globally acceptable macronutients and micronutrients are added to the base material to produce the agricultural fertilizer/conditioner. The macronutrient materials include phosphate rock, hydrated lime, gypsum, potassium hypochlorite, calcium hypochlorite, ammonium nitrate, potash, ammonia prills, and liquid ammonia.
