In Heap Leach the gold ore is laid on the perforated HDPE pipes by layers. On every ore layer drip irrigation pipes are placed to cover the whole ore area. By means of drip irrigation pipes cyanide solution is poured on the ore layer.

Cyanide passes through the gold ore and resolves the ore. This enriched solution is filtered down by means of gravity and goes into the perforated pipes. Thereafter the resolved solution is transferred to the collector pipeline through the drainage pipes.
