National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

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.
