Crushing Stage: Employing a “three-stage closed-circuit” configuration—jaw crushers for primary crushing, cone crushers for secondary crushing, followed by a closed-circuit fine crushing circuit using a short-head cone crusher + vibrating screen. This reduces ore particle size to 12-15mm, alleviating the burden on subsequent grinding.
Grinding Stage: Employing “single-stage/two-stage closed-circuit grinding” (ball mills paired with spiral classifiers or hydrocyclones), grinding ore to achieve 65%-85% passing -200 mesh to ensure thorough liberation of copper minerals;
Flotation Stage: Typically employs a “one roughing, two cleaning, two scavenging” or “one roughing, three cleaning, three scavenging” process. Adds butyl xanthate (collector) and No. 2 oil (foaming agent). For complex ores, lime is added to adjust pH and suppress gangue minerals. Ultimately produces copper concentrate with grades of 18%-28%, achieving recovery rates of 85%-95%
