Mastering Oxidized Gold Ore Processing Techniques
The first step in oxide gold ore processing is the mining of the ore itself, followed by the primary crushing of the gold containing rocks. This step is important because it helps to simplify the material for further processing in other steps. The smaller ore pieces are then transported to a ball mill after the first crushing.

Gold processing
Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for …
