Presence of metal elements in Transbaikal coals

General information on the presence and features of metal elements in coal is given in terms of genesis of coal deposits in Transbaikal area. The presence and contents of gallium, germanium and beryllium in Transbaikal coals are described using the values of the abundance ratio and average background content. The most promising deposits in terms of content of these elements in Transbaikal area are reviewed. Uranium mineralization and its influence on uranium content of coal in Transbaikal metallogenic province are characterized. General data on coal deposits as sources of rare earth elements are given. Some areas in Transbaikal deposits hold high concentrations of niobium, strontium and boron. Appraisal and recoverability of these elements need special research. Coals also contain noble metals of gold, silver and platinoids. The available data are reflective of nonunifom spread of these metals in coal, which makes difficult to identify genesis and distribution patterns of these elements within the limits of coal deposits. In the meanwhile, it is hard to make an unambiguous decision on the use prospects of these elements. The possibilities of further studies into contents of noble metals in coal deposits in Transbaikal are discussed. General data on the presence and content of tungsten and molybdenum are given. The further detailed research into metal elements in Transbaikal coal with a view to using them as composite mineral resources is justified.
