High Gradient Magnetic Separation tests have been carried out on low grade refractory copper ores, consisting mainly of cupriferous micas. An effective concentration of copper was obtained for two types of ores. The copper grade was improved 2 and 1.5 times at a recovery of about 90%. In particular, the amount of quartz in the concentrate could be reduced. This indicates that HGMS could be a successful method for concentration of these ores.
