Jan 23, 2012· Step #6 – Mining samples and determining processing Once mining gets underway, samples must be taken to determine the precise metallurgical qualities of the ore This is done in order to determine the appropriate processing technique Step #7 – Processing (on-site) Once ore is extracted, processing it into pure gold must be done
For extracting gold from low-grade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code Gold refining
Patio process, also called Mexican process, method of isolating silver from its ore that was used from the 16th to early in the 20th century; the process was apparently commonly used by Indians in America before the arrival of the Europeans The silver ore was crushed and ground by mule power in arrastras, shallow circular pits paved with stone
