Solutions for recovering metals - Metal

The mining industry relies on Calgon Carbon’s Granular Activated Carbon (GAC) to recover gold and other precious metals. Calgon Carbon’s ISEP® Technology is used to recover precious, rare earth and base metals, uranium, copper, nickel and zinc from ore, waste and reclaim streams. Our high-quality activated carbons have been developed and successfully proven to maximize efficiency by reducing the loss of precious metals and the consumption of carbon in three precious metal extraction techniques: Carbon-in-Leach (CIL), Carbon-in-Pulp (CIP) and Carbon-in-Column (CIC). When Ion Exchange is employed for metal recovery in leach and waste streams, Calgon Carbon’s ISEP ® system provides a continuous, consistent and high purity concentrated product while minimizing the use of chemicals, resin and wastes. Calgon Carbon’s continuous ion exchange systems are the most flexible, robust, and accepted in the industry.

Calgon Carbon’s GAC products offer the best value in the industry because of the following properties:

  • Higher gold adsorption capacities for maximum gold loadings
  • Excellent gold adsorption rates for high throughput
  • Superior hardness to minimize gold losses and prevent plugging of screens
  • Ability to liberate gold quickly and efficiently

Significant improvements have been made in the still evolving carbon-related technologies for gold and silver recovery. Calgon carbon’s experiences in the last decade have provided great advancement in our knowledge of the adsorption process and carbon specifications.

The advantages offered by Calgon Carbon’s continuous ISEP® System have been employed by Mining and Chemical Industries for Recovery, Separation and Purification of metals. The main advantages:

  • Reduce Resin Inventory up to 70%
  • Minimize Chemical Consumption by 20-40%
  • Reduce water usage
  • Decrease Waste Volumes by up to 50%

 Rest assured, our technical expertise and capabilities will help provide the most economical and efficient solution for your application.
