US Patent:

51981904, Mar 30, 1993

Filed:

Dec 21, 1990

Appl. No.:

7/632000

Inventors:

Carl T. Philipp - Hot Springs AR
Bobby H. Sims - Hot Springs AR

Assignee:

Enviroscience, Inc. - Little Rock AR

International Classification:

C22C 3304

US Classification:

420582

Abstract:

A method of recycling hazardous and non-hazardous industrial wastes to reclaim valuable metals, metal alloys, and metal oxides, and to produce mineral wool. Wastes including hazardous wastes of USEPA Series D, F, P, K, and U are pulverized and blended with liquids such as water or wastewater to produce a homogeneous mass. Calcium from calcium-stabilized wastes is used to enhance the quality of the mineral wool, lower the sulfur content, remove phosphorous, and raise pH to facilitate metal reduction. The mass is formed into briquettes and melted in a cupola or shaft furnace in the presence of carbon or aluminum to reduce metals. Other types of furnaces such as an electric arc furnace may be used to avoid the steps of forming and curing briquettes. Reduction is carried out at temperatures between 1660 and 3100 degrees Fahrenheit. Reducible metals are reduced and drawn off into molds.

Filed:

Nov 20, 1978

Appl. No.:

5/961985

Inventors:

Bobby H. Sims - Hot Springs AR

International Classification:

H01H 4700

US Classification:

361178

Abstract:

An apparatus for monitoring and controlling the liquid level in a storage tank which involves placing at least two magnetically operated switches, e. g. , magnetic-reed switches, at different levels in the tank and causing a magnet-containing float to move in response to the liquid level to activate these switches. A relay operates upon activation of the higher of these switches to start electrical current flowing to operate a discharge pump, thereby controlling the liquid level in the tank. In a preferred embodiment, a third magnetically operated switch is employed so that when the magnet activates the third switch at least one indication, e. g. , sound and/or light alarm, is given that the liquid level is at least at a predetermined level.

Enviroscience, Inc. - Hot Springs AR

International Classification:

C21B 1100

US Classification:

75500

Abstract:

A smelting process for blending hazardous and non-hazardous inorganic industrial wastes with carbon or aluminum reducing agents to simultaneously recover metal alloys (reducible metals), metal oxides (volatile reducible metals), carbon dioxide and man-made vitreous fiber (non reducible metals). Wastes including hazardous wastes of U. S. EPA Series D, F, P, K, and U are pulverized and blended with liquids such as water or waste water to produce a homogeneous mass. The mass is formed into briquettes and melted in a cupola or plasma arc furnace in the presence of carbon or aluminum to reduce metals. Other types of furnaces such as an electric arc furnace may be used to avoid the steps of forming and curing briquettes. Reduction is carried out at temperatures between 1660 and 3100 degrees Fahrenheit. Calcium flux from calcium-stabilized wastes enhances mineral wool quality, lowers the sulfur content of metals and raises pH to facilitate metal reduction.

International Classification:

C22B 700

US Classification:

75414

Abstract:

The present invention relates to a process for the production of metal alloys, metal oxides and slag-based products, such as mineral wool, from industrial waste materials. More specifically, the present invention relates to a process for recycling industrial waste materials into valuable commercial products, including, pure metals, metal alloys, metal oxides, and a molten slag comprising non-reducible metal oxides which thereafter can be converted to vitreous fiber and shot. Industrial waste materials suitable for use in the present invention include metal-containing waste products, particularly inorganic hazardous waste materials. The present process accomplishes total recycling in such a manner that the entire industrial waste material is consumed and converted to useful products.
