Mining and Mineral Processing: Process Water Treatment

Kiera Bulger | June 13, 2019

The Challenge:

Process water is used in industrial processes and production facilities following extensive water pre-treatment such as softening or demineralizing. The objective of treatment to process water is to be able to recycle the water for reuse and feedback into the industrial process. Process water created from the mining and mineral processing industry is commonly contaminated with suspended solids, metals, acids, and salts.

The Solution:

  • Water Treated: Wash water, effluent and run-off, heavy solids, clays, and biomaterials.
  • Chemistry Used: GFT 4900
  • Chemistry Replaced: polyDADMAC
  • New Dosage: 4-10 ppm
  • Old Dosage: 20-35 ppm

The Results:

The use of GFT 4900 resulted in significantly faster settling time and reduced sludge volume. The lower dose requirement reduced overall treatment costs by 10%. GFT 4900 is able to coagulate tough-to-treat clay and produced larger and denser floc particles, resulting in increased water clarity and color removal (from clays).
