Gold Recovery

In gold recovery, every ounce makes a difference.

Choosing the proper activated carbon for your application is critical for maximizing recovery. Our activated carbon products for precious metal recovery accomplish your goal of achieving maximum profits by reducing loss and improving yield.

Specialized Activated Carbons:

Coconut-based activated carbons are typically chosen because of the superior hardness, tight pore structure, and high activity pores.


Calgon Carbon’s Specialized Gold Carbons:

Gold Plus – Cost-effective coconut-based GAC designed and optimized for gold recovery operations.

DG 11 & DG 13 – High-performance coconut-based GAC designed and optimized for gold recovery operations.


For gold recovery circuits, it is essential that the activated carbon employed provides excellent process performance, minimal attrition loss and minimal maintenance problems. Significant improvements have been made in the still evolving carbon-related technologies for gold recovery. Calgon Carbon’s experiences in the last decade have provided great advancement in our knowledge of the adsorption process and carbon specifications.

Calgon Carbon’s activated carbon products offer the best value in the gold recovery industry because of the following advantages:

  • 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 more quickly and efficiently

Our technical expertise and capabilities will provide the most economical and efficient solution for your precious metal recovery application.

Gold Recovery Processes:

Carbon-in-column (CIC)

Ore is leached, typically in heap-leach, and clarified solution fluidized in column with carbon.

Carbon-in-pulp (CIP)

Pulp is leached in fluidized column, then leached pulp and solution contacted with carbon columns.
