  • Pre-concentration at crushing sizes for low-grade ores

    01/03/2020· Mineral processing of low-grade ores requires high processing flow rates. Pre-concentration is a clever technological solution for this challenge because the rejection of barren rock, in the early stages of the processing flowsheet, leads to increasing the head grade of the concentration plant and reducing the corresponding input flow rate. As pre-concentration at crushing sizes depends
