Mine Drainage Applications

An ideal metal removal treatment sequence for mine drainage water is a settling pond followed by treatment with an Octolig MRP (Metal Removal Plant). Lime is added to the incoming drainage water to increase the pH to an optimum pH for Octolig treatment. At the increased pH, high concentrations of heavy metals may produce some heavy metal precipitation in the settling pond.

After the addition of lime to the mine drainage water, the heavy metal concentrations remaining in the drainage water usually are greater than the permitted limits. Passing the settling pond's overflow through the Octolig MRP consistently reduces the heavy metal concentrations to a fraction of a part per million.

Octolig MRP system requires little maintenance and has low operating costs, which make it ideal for an economical metal removal treatment system for mines
