Reactions of Mineral Matter and Trace Elements

This general lack of interest in the chemistry of the mineral constituents is unfortunate in view of the increasing recognition of the importance of the minerals in conversion as well as the toxicity of some trace elements, especially the heavier metals. On this latter aspect, it is worthy of note that there is a high potential for the recovery of valuable mineral elements from coal conversion processes as added-value products in addition to their removal from the system prior to the onset of adverse effects on the environment.
