    Apr 05, 2021 · The hydrometallurgy is a main method of gold extraction. The leaching process as an important part of hydrometallurgy can be classified into three species depending on the different leaching conditions: under acid phase (pH < 3) with chlorine, thiourea [], ferric chloride, and thiocyanate []; under neutral phase (pH within 5–9) with halogens [] and thiosulfate []; and under the alkaline

  • agglomeration drums for processing gold ore

    agglomeration drums for processing gold ore

    One such advancement, is the use of agglomeration drums in the heap leaching process. The process of heap leaching extracts gold from ore by piling up crushed ore and applying a leaching agent to permeate through the pile, separating the gold from the ore. While this method has been used for decades with success, it has been greatly improved by the addition of an agglomeration drum to the process before …

    Heap leaching is a low-cost technology used in industrial mining to recover precious metals such as gold and uranium, along with several other highly sought after metals like copper, from their primary resources (ores and minerals). For many decades, there has been a growing demand for heap leaching due to its environmental benefits. Heap leaching provides mining operators with a benign
