methods, and the overall costs are similar. FLOWSHEET OPTIONS CRUSHING FOLLOWED BY DUMP OR HEAP LEACHING WITH CYANIDE This method of gold recovery is the preferred method for treating lowgrade gold ores because of its low cost. Between 1020% of the gold recovered each year from primary sources is extracted by this technique.

As the difference between gold and silver prices decreases ( the compression of the ratio), history suggests silver prices can make big moves upwards in price. The goldtosilver ratio compression is now at high levels and may eventually revert to its longterm average, which implies a strong movement in prices is imminent for silver.
