Abstract: A system and method for dispensing a treatment fluid is provided. The system includes a surface maintenance machine, a fluid reservoir, an air blower, and one or more fluid dispensing systems. The one or more fluid dispensing systems each include one or more nozzles in fluid communication with the air blower. The air blower generates an air pressure and dispenses air through the one or more nozzles while the treatment fluid is dispensed through the one or nozzles. The dispensing of air and treatment fluid dispenses the treatment fluid in a mist, fog, or spray to a surface. A method for dispensing a treatment fluid is also provided. The method includes generating an electrically charged treatment fluid and dispensing the electrically charged treatment fluid from the one or more nozzles to a surface.

Abstract: The present invention relates to a sulfation method which processes a rare earth containing material. The material is roasted and exposed to a sulfur gas, then an aqueous leach to produce an insoluble metal oxide and a soluble rare earth sulfide. The insoluble and soluble material are separated utilizing a solid/liquid separator. Advantageously, the process eliminates the need for additional steps to precipitate the metal oxide in order to separate the metal from the rare earth. A system is also disclosed.
