The GEOCOAT™ Process - A heap leaching process that is capable of bioleaching copper concentrates. It does this by coating the concentrate slurry onto a support rock, or substrate material, and stacking this coated material in a bioxidation heap. The support rock itself may be a low-grade copper ore. The ratio of support rock to concentrate is in the range of 5:1 to 10:1 by

Heap leaching - Revolvy. · Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore via a series of chemical reactions that absorb specific minerals and then re-separates them after their division from other earth materials.

The heap leaching technology has seen substantial growth over the past few decades, becoming a key process in mining; NAUE, a group specializing in geosynthetic liners, assesses that over 30% of copper and gold produced each year is beneficiated via heap leaching, up from only about 3% decades earlier.
