Gold mine switches to Watson-Marlow Qdos and Bredel APEX pumps

A gold mining company with assets in one of the most prolific gold-producing regions of Canada is now benefitting from the adoption of Qdos and APEX peristaltic pumps from Watson-Marlow Fluid Technology Group (WMFTG).

Deployed in two important applications, Harte Gold Corporation is now enjoying far better flow rate efficiency, along with significant reductions in both maintenance requirements and downtime. The company is subsequently looking to invest in further pumps from WMFTG.

Harte Gold operates the wholly owned Sugar Zone Mine, located on the Dayohessarah greenstone belt in Ontario. The mine entered commercial production in 2019 and has an operating life of approximately 13 years at current output levels. Producing 60,000 to 65,000 ounces of gold per year at 800tpd (tons per day) throughput rate, a mine expansion study is currently in progress to support 1200tpd.

Efficiency challenge

In the reagents room, Harte Gold operates eight diaphragm pumps on a 24/7 basis. However, issues over insufficient process efficiency, the amount of maintenance time needed to replace diaphragms, and the potential for leaks, prompted the company to look at alternative solutions.

Harte Gold invited WMFTG to trial its Qdos 30 chemical metering pump. For one month, the mining company compared the Qdos and an existing electric diaphragm pump, dosing flotation reagents such as potassium amyl xanthate (PAX).
