[0003] (1) After heating, it needs to be taken out and squeezed with a large glass rod while it is hot. Due to the high temperature of the test tube, it is easy to cause burns.
[0004] (2) It needs to be squeezed 200 times with a large glass rod, which greatly increases the labor intensity of the analyst
[0005] (3) The test tube is cooled quickly in the air, and the gold element may be adsorbed again, resulting in a low result

The invention provides a gold assisted-separation device and method and belongs to the technical field of geological sample analysis and tests. The device comprises an indicator lamp, a switch, a temperature sensor, an electronic temperature control device, a buzzer, a time relay, an electric heater, an ultrasonic transducer, an ultrasonic generator and an ultrasonic cleaning tank; the indicator lamp and the switch are arranged in parallel on an operating panel; the temperature sensor is arranged inside the ultrasonic cleaning tank; the buzzer is connected with the time delay; the time relay is arranged under the electronic temperature control device; the electronic temperature control device is connected with the electric heater; the ultrasonic cleaning tank is arranged on the upper part of the electric heater, while the ultrasonic transducer is arranged on the lower part of the electric heater; the ultrasonic cleaning tank is a cube-shaped container; the ultrasonic generator is arranged on the outer side of the container wall of the ultrasonic cleaning tank. According to the gold assisted-separation device, after the gold element in a chemical prospecting sample or a rock mineral sample is separated and enriched by use of foam plastics, ultrasonic assisted separation is adopted, and the stirring and dispersing effects can be added to accelerate the separation of the gold element.
Description
technical field [0001] The invention belongs to the technical field of geological sample analysis and testing, and in particular relates to a device and method for assisting gold release. Background technique [0002] Gold element is often present in a non-uniform state in geological samples, and the content of gold in nature is extremely low. In order to avoid errors caused by sampling, it is necessary to take large samples (generally more than 10g). Furthermore, it was determined that when analyzing gold elements, separation and enrichment techniques must be used to remove a large number of rock-forming elements and improve the sensitivity of the test. Common separation and enrichment methods include solvent extraction, activated carbon adsorption, ion exchange adsorption, and foam plastic adsorption. The most used at present is the foam plastic adsorption method. However, this method has the following defects in the process of liberation: [0003] (1) After heating, it...
