For mine owners and project developers evaluating oxide copper resources, the SX-EW process offers a proven pathway from ore to metal. With appropriate equipment selection and process design tailored to specific ore characteristics, this flow sheet can be adapted to operations of varying scale—from small, high-grade deposits to large, low-grade bulk tonnage projects.

Yayin da bukatar ruwan zinc ke ci gaba da haɓaka kuma masana'antar tana ƙara komawa zuwa ga albarkatun oxide don ƙara yawan samar da sulfide, tsarin SX-EW ya kasance fasahar zaɓi don dawo da ruwan zinƙi mai inganci, mai araha, kuma mai jituwa da muhalli.
