The output of gold mine investment is gold, which is loved by consumers all over the world and well-known by investors. Against the backdrop of collective gold reserves increase in China, Russia and other countries, global gold consumption and investment demand are growing, which provides a sales guarantee for gold mine output. Whether it is investing in gold jewelry or investment products, there is huge market potential.
The
gold ore processing and production process mainly includes three processes: crushing, grinding and beneficiation:
In the crushing process, three-stage closed-circuit crushing is a modern method suitable for gold ore crushing, which can complete the work of ore crushing and partial dissociation, thereby improving the subsequent grinding efficiency;
In the grinding process, two-stage one-closed grinding can make the gold ore more fully ground;
In the beneficiation process, due to the different types and properties of gold ores, the beneficiation methods used are also different, but gravity separation, flotation, mercury mixing, cyanidation and today's resin slurry method, carbon slurry adsorption method, heap leaching method are generally used for gold extraction. For some types of ores, a combined gold extraction process is often used.
The first stage: crushing and screening - three-stage closed-circuit crushing
The large pieces of gold ore are evenly fed into the
jaw crusher or the
mobile crushing plant for coarse crushing by the vibrating feeder through the silo; the coarsely crushed gold ore is screened by the vibrating screen and sent to the single-cylinder
hydraulic cone crusher by the belt conveyor for medium crushing; the gold ore material after medium crushing is sent to the multi-cylinder hydraulic cone crusher for fine crushing;
The second stage: grinding
The 0-12 mm gold powder screened by the
vibrating screen is evenly fed into the grinding machine for grinding, and screened by the spiral classifier, and those that do not meet the requirements are sent to the grinding machine for further grinding;
The third stage: ore dressing
In the ore dressing process, due to the different types and properties of gold ores, the ore dressing methods used are also different, but gravity separation, flotation, mercury mixing, cyanidation, and the current resin slurry method, carbon slurry adsorption method, heap leaching method are generally used for gold extraction. For some types of ores, a combined gold extraction process is often used.
