Abstract:

Because gold has the features of high corrosion resistance，good electrical conductivity and thermal conductivity，thus those features have been widely used in industry.Due to the existing gold smelting and processing technology had characteristics of long cycle，low efficiency，big reagent consumption，high energy consuming and operation process complex faults，therefore，in recent years，ultrasonic technology has already been applied extensively in various fields，developed well，and achieved good results.In this paper，we summarized and analyzed the application of ultrasonic technology in gold leaching，nanometer materials preparation，chemical plating and gold testing.The results demonstrated that compared with the application of traditional technology in the fields mentioned above，the ultrasonic technology presented the features of high efficiency，low energy consumption，wide application and ease of automation control，etc.With the development of the research on the basic theory of ultrasonic and continuous improvement of ultrasonic equipment，ultrasound technology will be favored and widely employed for the refractory gold ore，new material preparation as well as nondestructive testing，etc.

Key words: ultrasonic technology, gold leaching, gold smelting and processing, refractory gold ore
