of high-grade ore per year for 8 years. The deposit contains 0.12 ounces of gold per ton of high-grade ore and can be acquired at a cost of $10 per ton of ore (cost of mining ore at site). A sodium cyanide process is used to extract the gold from the ore, and various other processing techniques are used to produce 99.9% pure gold bullion from ...
Research on leaching of carbonaceous gold ore with copper …
the leaching of gold and silver from their ores was known as early as 1888 (Marsden and House, 2006). Cyanidation process has been the most successfully practiced method for gold extracting from ores over the past 100years.

Use of quaternary ammonium salts to remove copper
The extractant is dissolved in a supporting matrix (or diluent), such as kerosene or octane, for the metal extraction (Marsden and House, 2006). The use of quaternary ammonium salts may be an attractive alternative in some applications due to its good selectivity and high extraction capacity ( Davis et al., 1998, Marsden and House, 2006 ).
