On this issue, the best method of chip gold extraction is to use chemical methods to extract. This method can be used to extract the gold from the chip by using special chemicals.
One of the common methods is to use cyanide to dissolve the gold out, and then deposit the gold on the electrode by electrolysis or other methods.
In addition, the chip can be processed into small pieces using physical methods such as laser or plasma cutting, which can then be chemically extracted. No matter which method is used, it is necessary to pay attention to safety and environmental protection to avoid harm to the human body and the environment. Hello, the best method of chip gold extraction is to use chemical methods, such as hydrothermal, electrochemical or solvent extraction. These methods can extract metals from discarded electronic devices without much impact on the environment. In addition, these methods can also improve metal recovery and purity.

The wet method has the highest recovery rate, extracting \"gold\" from circuit board waste, and this method has a recovery rate of 98%.

The hydrometallurgical process allows the recovery and purification of specific metals from multi-element solutions using techniques such as selective leaching, solvent extraction, electrolytic extraction, the use of chelating resins and precipitation.

In addition, hydrometallurgy has a more selective metal recovery capability compared to fire metallurgy, with the added benefit of reducing gas emissions to the environment, and without any significant investment and operating costs.
