Abstract
Guidelines for developing microwave dissolution methods for geological and metallurgical samples are being investigated at the U.S. Bureau of Mines. By varying sample size, acid mixture, vessel type (open or closed), microwave power, and digestion times, procedures have been developed to successfully dissolve metals and minerals. A general scheme of microwave digestion and fusion methods is presented, as well as specific techniques for the dissolution of phosphate rock, ores, solder, superalloys, and other geological and metallurgical samples. Development of specific methods involves the selection of parameters that best exploit the chemistry of the sample matrix and the dissolution-enhancing effects of microwave radiation.
