GreenGold secures ReCYN technology contract at Martabe gold mine

A GreenGold employee carries out some preliminary test work.

Technology company GreenGold has won a contract to design and install its ReCyn technology at PT Agincourt Resources’ Martabe gold project in Northern Sumatra, Indonesia.

Martabe, which is one of the largest gold mines in Indonesia, will benefit from GreenGold’s detoxification system. ReCYN can recover base metals, precious metals and cyanide efficiently during tailings detoxification by using absorbent resin beads that can be imbued with different properties depending on the task at hand.

This can help to reduce cyanide consumption by up to 50 per cent by recycling free cyanide back into the leach circuit. GreenGold will implement its technology at Martabe to recover cyanide and copper that would otherwise have been lost, according to GreenGold chief executive officer Malcolm Paterson.

“We have come up with an elegant design to fit the space-constrained site,” explained Peterson.

“We also will be recovering cyanide and copper which previously was destroyed or sent to tails, turning a cost into an economic benefit for the mine.

“We are looking forward to delivering on this strategically important project, and continuing to build on our proven metallurgy and process capability within the precious/base metals sector globally.”

The Martabe mine hosts a resource of around 7.4 million ounces of gold and 69 million ounces of silver and employs around 2000 people.
