Problems solved by technology
At the same time, the temperature of the leaching environment is high, and the equipment will be strongly worn during the leaching process, resulting in a shortened service life of the leaching equipment.
At present, the mainstream leaching equipment on the market is conventional leaching equipment, which has the defect that it cannot meet the production needs
Individual equipment such as enamel reactors can meet the production requirements, but they are expensive, have very high requirements for transportation and processing, and have relatively small volumes, which cannot meet the production requirements well.
Although there are many acid-resistant, corrosion-resistant, temperature-resistant and wear-resistant equipment of different materials on the market, there are at least one performance that cannot meet the requirements of the gold extraction process

Embodiment 1
[0045] This embodiment provides a non-cyanide gold leaching device 600 for gold concentrate. refer to figure 1 As shown, it includes a tank body. In this embodiment, the tank body is a cylindrical tank body 1, and the tank body 1 is made of concrete. The manufacture of the tank body 1 can be done on site. In other embodiments, the tank body 1 can also be made of steel plate. The cost of concrete or steel plate is low, and the tank body 1 is made of concrete or steel plate. On the one hand, it can ensure that the tank body 1 has a certain mechanical strength, and on the other hand, it can also play a certain role of heat preservation.
[0046] In this embodiment, an insulation layer is provided on the outer periphery of the tank body 1 to keep the tank body 1 warm.
[0047] The insulation layer is made of rock wool, which has the advantages of low price, light weight and good corrosion resistance.
[0048] During manufacture, adopt ordinary reinforced concrete to make on-si...

The invention discloses a gold concentrate cyanide-free gold extraction leaching device, and relates to the technical field of gold concentrate cyanide-free gold extraction equipment. The leaching device comprises a tank body, the tank body is made of concrete or steel plates, a lining is arranged in the tank body and is formed by cementing a cementing agent and a lining material, and the lining material comprises at least one of acid-resistant ceramic, silicon nitride ceramic and impermeable graphite bricks. The gold concentrate cyanide-free gold extraction leaching device has the advantagesthat the corrosion resistance, temperature resistance, acid resistance and wear resistance requirements of the leaching environment can be met, in addition, the leaching device is moderate in cost andconvenient to manufacture and process, the specification can be adjusted according to the requirements, and all the process requirements of gold concentrate cyanide-free gold extraction can be met.
Description
technical field [0001] The invention relates to the technical field of equipment for non-cyanide gold extraction of gold concentrate, in particular to a leaching device for non-cyanide gold extraction of gold concentrate. Background technique [0002] The leaching device is an important equipment in the non-cyanide gold extraction process of high sulfur, high arsenic and carbon refractory gold concentrate. In the non-cyanide gold extraction process of gold concentrate, the leaching environment is strongly acidic and moderately oxidizing. At the same time, the temperature of the leaching environment is relatively high, which also causes strong wear and tear on the equipment during the leaching process, resulting in a shortened service life of the leaching equipment. At present, the mainstream leaching equipment on the market is conventional leaching equipment, which has the defect that it cannot meet the production demand. Individual equipment such as enamel reactors can me...
