Video of pool intrusion of gold oxide ore

2. The electrolyte caused by electroplating is not cleaned up.

3. Not necessarily
it depends on the environment
if the conditions are appropriate
it may also be completely oxidized

4. Gold is a metal with relatively weak activity. Generally speaking, it is difficult to oxidize. Under certain conditions, such as pure oxygen, the oxygen concentration is high, so it can be oxidized slowly. In addition, in the presence of pure chlorine and fluorine gas, heating at the same time, the reaction may also occur

5. Yes, it can form oxide au2o3 with oxygen at high temperature.

6. Cyanidation come on! Adsorption with activated carbon! You can keep asking me!

7. Rich experience, exquisite technology, less harmful substances in ore, reasonable process selection, and quick money from oxidized gold ore.

8. Unknown_Error

9. 1. Gold is difficult to be oxidized. Gold can form oxides through a long time of slow oxidation process, such as underground mineralization
2. It can be oxidized:
Au + 2H + + 2cn - + NO3 - = = = [Au (CN) 2] - + NO2 + H2O
this is the traditional gold smelting method

3. The distinction between combustible and nonflammable must be combined with environmental factors (combustion supporting substances). For example, sulfur is combustible in hydrogen and air, and nitrogen is nonflammable in oxygen

10. Anything will oxidize, just fast or slow
