    Gold Extraction an overview ScienceDirect Topics

    The increase in gold extraction can be attributed to increases in residual Cu (II) in solution with increasing pH value resulting from the increase in free NH 3 ( Senanayake, 2004a,b ). Leaching at a higher pH value can also be beneficial in improving silver extraction and stabilizing silver in solution.

    What is Gold Extraction? (with pictures)

    2021/02/24· Comminution, hydrometallurgy, and pyrometallurgy are used to extract the gold. Comminution is often one of the first steps in gold extraction.
