  • COPPER Copper production TU Delft

    Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 – 1 % Cu) must be concentrated by beneficiation.

  • Preconcentration at crushing sizes for lowgrade .

    · 1. Introduction. One of the main challenges of the mining industry is the processing of lowgrade ores. This type of ores obliges high processing plant throughput rates, which would result in increased energy consumption and operational costs (Wills,, McGrath et al., ).It has been referred that, on average, 44% of the total electricity consumption is dedicated to crushing and milling
