Abstract:

Mechanical agitation leaching trough is the means for the implementation of key equipment and technology of cyanidation，but due to the short of the complex driving structure and the high energy consumption，the mechanical agitation leaching trough has been replaced by air-strength agitation leaching trough in some refiner.This paper briefly introduces the development history of cyanide leaching process，analysis the advantages and disadvantages of air-strength agitation leaching trough，working principle，operating pneumatic agitation leaching.The application practice in gold concentration plant show that，the air-strength agitationg leaching trough have the advantages of simple structure，easy to repair，power saving，high leaching rate，wide application prospect.

Key words: flotation, cyanide leaching, continuous agitation cyanidation, leaching rate
