Montana Resources CAVEX® Success Story

What do you do when unreliable hydrocyclones lose you 10,000 tons of ore per month on downtime? At Montana Resources copper mine, this problem was exacerbated by poor classification that was negatively affecting downstream flotation recovery — so they turned to our team for a solution. We retrofitted their grinding circuit with CAVEX® hydrocyclones and added spare units without changing their existing footprint. The results? ✅ Up to 2% improved copper recovery ✅ Increased, reliable wear life ✅ Hydrocyclone maintenance completed without mill shutdowns And the best part? Their first CAVEX® cyclone didn’t need parts replacement until 2.5 years of continuous operation.
