Foreign conventional mixing apparatus also mercury amalgamation continuous cylindrical former Soviet Union Research and Design Institute Ural copper industry developed (FIG. 1), which is from the discharge port feed mill rotating cylinder, the mercury contents removable plate (copper) Can work continuously. In addition, there is a short cone hydrocyclone for fine gold particles mixed with mercury, and a mercury-mixing plate for laying on a chute and a shaker. Figure 1 Continuous Mercury 1-cylinder; 2-transmission mechanism; 3-mercury heater; 4-support roller; 5-end cap In addition, some new types of amalgamation equipment have been developed recently at home and abroad. These equipments mainly include swirling amalgamators. 1. Swirl amalgamator It is based on the principle of a hydrocyclone and is used in the second stage of the grinding circuit in mines in the United States and South Africa. The slurry is sent to the equipment for adding mercury and rotates in the tangential direction. At this time, due to the strong agitation of the slurry and mercury, the contact between gold and mercury is promoted during the continuous movement, so that the amalgamation operation can be enhanced, so the mercury mixing efficiency is higher. . Second, continuous amalgamator China's self-designed centrifugal continuous amalgamator (Fig. 2) feeds the slurry into the mercury bed in the mercury amalgamator. The water pressure of the centrifugal circulating water pump causes the ore to rotate on the mercury bed. At this time, due to the centrifugal action, the ore is stratified, and the dense gold particles are precipitated on the surface of the mercury bed and the mercury layer is swept and trapped and mixed. After the mercury is mixed, the water, heavy sand and mercury in the slurry are siphoned into the tube by the bell mouth. When the slurry enters the spherical chamber, due to the sudden increase of the section, the mercury begins to flow under the action of gravity, while the water and heavy sand with low density continue to rise into the separator and are discharged by the overflow pipe. The resulting amalgam is sunk into the bottom of the mercury bed due to its greater specific gravity than the newly added mercury and is periodically released from the valve.

Mercury is recycled for use and mercury paste is periodically removed. After the slurry is mixed with mercury, it is lifted by a siphon and discharged from the discharge pipe, thereby realizing the continuation of the amalgamation operation. Third, dry electric amalgamator The dry electric amalgamation machine developed by the United States, through high-voltage current, causes the suspended gold particles to contact with mercury. This amalgam collector is capable of recovering particulate or gold in the form of a cement. Fourth, electric amalgamation machinery This is a mechanism in which the cathode of the circuit is connected to the surface of mercury to reduce the surface tension of mercury, activate the wetting property of mercury, and improve the efficiency of mercury mixing. Foreign countries have made electrical amalgamation boards, electrolyzed centrifugal amalgamation machines, electrical gold extraction buckets and other equipment. In addition, there is also a mercury-mixed tower developed in France and a portable sorting-amalgam combined machine for recovering gold from coastal sand mines (Fig. 3).
