RESEARCH ON THE TECHNOLOGY OF ACID LEACHING PURIFICATION OF DIATOMITE ORE UNDER THE MICROWAVE FUNCTION

Based on the demands of the technology on acid leaching of diatomite ore and the microwave characteristics, a new technology for purification of diatomite by microwave including purification of diatomite by microwave pre-treating and by microwave acid leaching was proposed. The results of the experiments indicated that microwave could promote and strengthen acid leaching purification of diatomite ore.
