In addition to coconut shell gold charcoal, there are other types of activated carbon that can also be used to extract heavy metals, such as:
Apricot kernel activated carbon: Its adsorption capacity and rate are close to coconut shell activated carbon, and the cost is lower. Apricot kernel activated carbon performed well in the test of adsorbing gold, with low gold content in the tail liquid and high gold recovery rate.
Peach kernel activated carbon: The adsorption capacity and rate of peach kernel activated carbon are also high, and peach kernels are widely distributed in my country, with large output and easy collection, making it an ideal substitute.
Wooden columnar gold-specific activated carbon: This activated carbon is made of high-quality wood raw materials, with a black granular appearance, suitable for gold extraction.
