Study Notes

Mining Industry and Tailings Management

  • The mining industry is experiencing growth, increasing the need for efficient tailings management.
  • Densified tailings are generated as a byproduct of mining processes, requiring effective handling to minimize environmental impact.
  • Densification techniques typically use thickeners to concentrate solid materials from tailings.
  • Occasionally, thickening processes do not reach the planned solids mass concentration, leading to operational challenges.
  • Achieving optimal densification is crucial for resource efficiency and reducing water usage in tailings management.
