ABSTRACT:
The present invention provides a leaching or smelting precursor method of drying and heating particulate ores or concentrates which have been previously intimately admixed with either an already active form of carbon or with some other carbon-containing material which can be readily dried and heated to charring temperatures by microwave energy comprising irradiating the composite with microwave energy.
