CyPlus installs cyanide-control system in Sweden

By Gerald Ondrey |

Dragon Mining Sweden AB (Storuman) has purchased the CyPlus CCS Cyanide Control System from CyPlus GmbH — a wholly owned subsidiary of Evonik Industries AG (Essen, Germany; www.evonik.com) — for its Svartliden operation in Sweden. “Working closely with Svartliden’s personnel, the CyPlus unit was successfully commissioned on site and operators have been trained to use CyPlus CCS,” says Bernd Adam, senior applications specialist in the CyPlus team from Hanau-Wolfgang, Germany, who installed the unit in Sweden. CyPlus CCS is a proven system to measure cyanide content and optimize cyanide additions to the tank where the gold-bearing ore is treated. “We always need the optimal concentration of cyanide in the leach tank and it is essential to avoid over- and under-dosing. With the CyPlus CCS we expect to reach our cyanide-related goals,” says Matthias Koot, project engineer of the Dragon Mining Svartliden operation. The analytical apparatus measures concentrations of different strengths at several points. Gold mining operations need to maximize the gold extraction rate yet minimize consumption of cyanide and cyanide destruction reagents to comply with stringent limits, for example those set by the…
