The advantages of the liquid chlorine method are mainly the high leaching speed of gold, the high leaching rate of gold, the convenience and cheapness of chlorine gas production, the consumption of chlorine gas is also higher than that of banknotes, and it does not pollute the environment. Therefore, the liquid chlorine method is a promising mention. Gold method. The method is most suitable for treating gold-containing oxidized ore. If it is used to treat gold-bearing sulfide ore, in order to avoid the reaction of sulfide and chlorine gas to consume a large amount of leaching agent, the gold ore may be oxidized and calcined in advance to remove sulfide minerals and then chlorinated and leached. , so that the gold can leach rate 99.3% 92.2 ~; if for processing gold - copper ore, in order to reduce unnecessary consumption caused by the leaching agent and a base metal chloride, gold ores need to be pretreated It is calcined or leached with dilute acid to remove copper, zinc , iron and other base metals, and then chlorinated.
EO Sterilizer :
ETO Sterilizer is a key equipment for single-use sterile medical device manufacturers. Ethylene oxide does not damage sterilized articles and penetration is very strong, so EO Gas Sterilization can sterilize most of the articles that are not suitable for general sterilization methods. For example, electronic instruments, optical instruments, medical instruments, books, documents, fur, cotton, chemical fiber, plastic products, wood products, ceramics and metal products, endoscopy, dialyzer and disposable medical supplies, etc.
Advantages of ETO Sterilization Machine:
1. All microbes can be killed, including bacterial spores.
2. Sterilized items can be wrapped and packaged, and they can remain sterile before use.
3. Relatively speaking, Ethylene Oxide Sterilization does not corrode plastics, metals and rubber, and does not make things yellowed and brittle.
4. Irregular objects can be penetrated and sterilized.
5. EO Sterilization can be used for sterilization of articles that can not be soaked with disinfectant, dry heat, pressure, steam and other chemical gases.
