gold extraction and processing

Gold Cyanidation Ground Truth Trekking

The resulting liquid is collected at the bottom, and the gold is chemically extracted. Heap leaching extracts less of the gold than processing the ore in a mill, but is much cheaper. There are a few alternatives to cyanide for processing low-quality ores but none are employed very widely to date (1).
