What is Gold Extraction? (with pictures)

A cyanide solution is introduced, which liquifies the gold, releases it from the rock, and allows it to drain away for processing. This method of gold extraction, also known as gold cyanidation, takes several months. Dump leaching is used to extract mostly lower quality gold and metals. It does not require the rock to be broken into small pieces and is cheaper and less effective. In some cases ...
