  • The Impacts of Copper Mining in Chile

    Copper Mining and Macroeconomic Indicators Copper mining has accounted for an average of 10% of Chile’s gross domestic product (GDP) for the last two decades In comparison, the mining industry as a whole represents 109% of GDP Between 1996 and 2016, copper mining as a percentage of economic activity in Chile ranged between 36% (in 1998)Figure 1: Overview of copper production 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 (05 – 1 %COPPER Copper production TU DelftAdvanced Process Control (APC) is now widely accepted as a way to optimize mining operations and help to surpass the challenges described above Existing advanced processcontrol technologies are consolidated and the combination of process control techniques hasIntegrated advanced process control with a sag mill
