摘要
W. ores in powder form are treated by transporting the ore in a gas stream, circulating the ore and gas into a plasma discharge, and reassembling the ore from the gas stream after it has circulated in the discharge. It is used for extracting W cpds. from e.g. (Fe, Mn) WO4 and Ca WO4, the ore being cooled sufficiently fast for the W cpds. not to combine with other metal oxides from the ores.
