Gold: While not as common as other methods, solution mining can be used for extracting gold from certain types of ore deposits, especially when combined with heap leaching operations. Potash: Solution mining is used to extract potash (a potassium salt used in fertilizers) from underground salt deposits.

The solution strips away the gold and is collected in a pond, then run through an electro-chemical process to extract the gold. This method of producing gold is cost effective but enormously wasteful: 99.99 percent of the heap becomes waste. Gold mining areas are frequently studded with these immense, toxic piles.

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 …
