Heap leaching facilitates the profitable extraction of gold from very low grade ore. Prior to heap leaching, either run of mine (ROM) or crushed ore is heaped into structures 10 to 20m high that are stacked on an impermeable layer. A dilute cyanide solution is sprayed on the heap, percolates through the pile and dissolves the available gold.

From its beginnings in 2012 until 2017, the El Gallo Mine produced 240,000 gold ounces and 125,000 silver ounces. During Q2 2018 mining and crushing activities at El Gallo ceased and contractor equipment has been demobilized from the mine site. Onsite operations continued through residual heap leaching for the remainder of 2018.

Cyanide Leaching, Mining, SGS. Cyanide leaching has been the industry standard for gold processing for more than 100 years. During the cyanide leach process, a cyanide solution, or lixiviant, is percolated through ore contained in vats, columns or heaps. Gold is dissolved by the cyanide and then removed from the heap or columns. The Mining ...
