Method and apparatus for optimization of energy coupling for microwave treatment of metal ores and concentrates in a microwave fluidized bed reactor

摘要

The present invention provides a new and useful method for controlling microwave energy distribution in the reaction chamber of a fluidized bed reactor by tapering the reaction zone of the reaction chamber so that the cross-section diameter at the lower end differs from the cross-section diameter at the upper end by a factor of {square root}. epsilon..sub.r .
