Description
Russia is a very rich country in gold resources, occupying the forefront of the global gold resource richness. In Russia, gold mines are mainly distributed in Sibur Region, Chukotka Autonomous Region, Krasnoyarsk Krai, Magadan Oblast, Khabarovsk Border Region, Sakha Republic and Yakutia Republic.
Russia's gold reserves are huge, natural reserves are roughly estimated to be about 5,000 tons, accounting for 10.8% of the world's natural reserves, is the world's third largest natural reserves of gold resources. Russia also leads the world in terms of proven reserves. According to statistics, Russia's proven reserves at the end of 2018 were 2522.1 tons.
Process
The principle of gold ore dressing production line is to recover gold and its related heavy ore from the raw ore by gravity separation, flotation, mercury mixing, magnetic separation, electrostatic selection and other combined effects to separate gold and various heavy ore for comprehensive recovery. Screening of gold ore is generally divided into crushing and screening, dust removal and separation processes.
1. Gold ore dressing production line crushing and screening many gold ore containing cement mud, its mouth also has more than 100 mm. This mud block will not be broken, and will be eliminated with waste rock in the physical process, resulting in gold loss. Mud can also adhere to crushed stone or gravel, and unbroken decomposition can also lead to gold loss during the screening process.
2. In gold ore dressing production lines, materials less than 0.1 mm generally contain no or almost no gold. Gold smaller than 0.1 mm, commonly referred to as suspended gold, is difficult to recover during the screening process, and mud of the same grain grade can hinder the screening process, especially machine-specific screening processes. Therefore, gold mining machines always want to remove less than 0.1 mm of mud. The dust removal equipment commonly used in production is the dust removal head of various specifications. Stapello allows for larger material sizes, large throughput, and often no desliming before sulfur is selected.
3. The implementation of the election law of gold ore dressing production line has proved that the reselection method is effective and economical in treating gold ore. In the sand gold mine, the particle size composition of gold is different, and the effective particle size boundary of the materials processed by various reprocessing equipment is also different, and the reasonable gold screening process must be the joint operation of several reprocessing equipment.
The flotation process of gold ore dressing production line is composed of jaw crusher, ball mill, classifier, mixing barrel, flotation machine, separator, separator, dryer and other main equipment, which can be combined with mining machinery, elevator and belt conveyor to form a complete mineral processing production line. This production line has the advantages of high efficiency, low energy consumption, high throughput and economy. The market is the key to solving all problems, but also to accelerate our growth, create a good space for development, so that enterprises enter a new stage, continuous development, to meet new challenges with strength, to add new reliable equipment to the mining machinery industry, enter a new stage.
Advantage
First, save electricity.
The power consumption of gold ore processing process is low, and the motor equipped with each equipment is reasonable, which ensures the rapid operation of the equipment and does not cause excessive power waste.
Second, save water resources.
The discharge of water resources in the flotation process of gold mine is less, which can realize the recycling of water resources and save the production cost.
Third, large processing capacity.
Gold ore processing production insurance components of the work performance is reliable, rapid operation, to ensure that the production line has a large processing capacity.
Fourth, reasonable layout.
The mineral processing process of gold mine is compact in structure and reasonable in layout, which is convenient for material circulation and personnel operation.
