The cyaniding tank 3 is a closable tank for placing the ultrasonic transducer unit 2 and the gold ore pulp and is used as a container for strengthening gold cyaniding leaching by ultrasonic waves. The umbrella-shaped mechanism 1 is used for fixing the ultrasonic transducer unit 2 and arranging the ultrasonic transducer unit 2 in the interior of the cyanide tank 3. In addition, the umbrella-shaped mechanism 1 can be unfolded and folded, and is convenient to put into the cyanide tank 3 or take out from the cyanide tank 3.

The extract in the method for the ultrasonic enhanced cyanidation leaching is gold, and can also be one of other heavy metals such as silver, platinum, copper and the like.
The working principle of the invention is as follows:
the high-power ultrasonic wave can play a role in strengthening leaching, and mainly because bubbles in a liquid phase generate cavitation under the action of specific sound waves, hot spots are instantly generated, namely high-temperature and high-pressure zones formed in the dynamic process of acoustic cavitation, the temperature can reach 5000 ℃, the pressure can reach 100MPa, the temperature time change rate can reach 108 ℃/s, and strong shock waves are accompanied. The ultrasonic wave mainly has the following three functions in the cyaniding leaching process of gold:
Cavitation activation effect: the shock wave generated by collapse of cavitation bubbles acts on the surface of the solid, the speed of the formed micro-jet is as high as l000m/ns, so that the surface of the solid is locally eroded and destroyed, or a film influencing leaching on the surface of the mineral and a passivation film generated in chemical reaction are removed, particularly impurities adsorbed in micro-cracks, gaps, defects, gaps of mineral blocks and partial intergrowth cracks can be removed, and the surface of the mineral is kept highly active. Under the action of shock wave, oxygen and cyanide can quickly enter gaps and cavities of the leached substance to make gold take part in reaction, so that the leaching rate of gold is increased.
Thermal effect: during cavitation, the sound-transmitting medium absorbs sound energy and converts it into heat energy. Under the action of high temperature and high pressure, the mass transfer effect is strengthened and the chemical reaction speed is accelerated.
Mechanical effect: the ultrasonic wave not only generates cavitation in liquid phase, but also generates mechanical effects of vibration displacement, speed and acceleration of mass points of the sound-transmitting medium, can refine grains, promote dispersion of fine particles, improve solid-liquid contact area in a reaction environment, also can improve chemical reaction conditions and play a role in strengthening leaching.
In conclusion, the high-power ultrasonic wave can improve the chemical reaction condition, accelerate the chemical reaction rate, improve the mineral leaching rate and reduce the dosage of chemical reagents, thereby realizing the enhanced leaching.
The working process of the invention is as follows:
firstly, the umbrella-shaped mechanism is folded and penetrates through the opening of the cyanide tank, when the whole mechanism enters the cyanide tank, the umbrella-shaped mechanism is unfolded, and the input port of the ultrasonic transducer unit is connected with the output port of the ultrasonic power supply through a cable. Then, the cyanide tank is filled with gold ore pulp and air to submerge all the transducers. And finally, starting a power supply, adjusting power supply parameters, enabling the ultrasonic transducer unit to be in an optimal working state, and enabling the gold ore pulp to generate a cavitation phenomenon under the action of high-power ultrasonic waves. Wherein, the cavitation effect generated by the cavitation phenomenon causes the local erosion and destruction of the surface of the gold ore particles, or removes the film which influences the leaching of the mineral surface and the passive film generated in the chemical reaction, thereby keeping the high activity of the mineral surface. Under the action of shock wave, oxygen and cyanide can quickly enter gaps and cavities of the leached objects to make gold take part in the reaction, thereby improving the leaching rate of gold; the heat effect strengthens the mass transfer effect and accelerates the chemical reaction speed; the mechanical effect of the method refines grains, promotes dispersion of fine particles, improves solid-liquid contact area in a reaction environment, can also improve chemical reaction conditions, and plays a role in strengthening leaching.
