Microwave Heating of Chemicals and Minerals.

PB95170536

Publication Date	1995
Personal Author	McGill, S. L.; Walkiewicz, J. W.; Clark, A. E.
Page Count	42
Abstract	The U.S. Bureau of Mines has determined the microwave heating rates for a suite of minerals and reagent-grade compounds. Maximum temperature achieved for the samples and the time required to reach temperature are reported. Descriptions of the microwave cavities, test cells, and a thermocouple assembly used to measure temperature in the microwave field are given. Applications demonstrating the use of microwave energy in mineral processing are described herewithin include oxidation/reduction reactions, mineral liberation, and mercury retorting/vaporization. Microwave data on mineral heating rates will provide insight to possible chemical and mineral processing applications as well as assist in predictions of processing parameters.
