Heap Leach Gold Extraction

Heap leaching technology is used in the extraction of precious metals such as gold from the natural ore. Vadivel Cocotech Activated Carbon gold series offers coconut shell based tailor-made products for heap leach gold extraction manufactured using cutting edge activation and processing technologies.

These carbon products are of high hardness and resistance to abrasion with very high and lasting gold adsorption kinetics and gold loading capacity ensuring effective and efficient adsorption with minimum loss of gold.
