Effluent management and treatment

As part of the water management system, and for some of the mentioned projects, effluent treatment systems have been designed for discharge into the natural environment, reuse as process water, or recovery of dissolved metals, through:

  • Precipitation of metals in the form of hydroxides by adding calcium carbonate or calcium hydroxide.
  • Precipitation of thiosalts by adding hydrogen peroxide.
  • Extraction of copper by ion exchange resins, followed by a stage of extraction and electrolysis of the enriched solution.
