Leaching Copper Pilot Plant

Bioleaching: Introduction, Methods, Application, Copper

In pilot plant reactors of 50 liter capacity, leaching can be performed continuously in a cascade series with recycling of cells and leachates. In the laboratory better yields of bioleaching products can be obtained under optimal conditions, like control of temperature, O 2 and CO 2 adjustments, maintenance of pH between 2 and 3, and eh around

COPPER PRECIPITATION AND CYANIDE RECOVERY PILOT

The process utilized in the pilot plant to precipitate copper from leach solution is commonly referred to as the Sulfidization, Acidification, Recycle and Thickening (SART) process. In this process, copper is precipitated from cyanidation solution as copper (I) sulfide following the addition of sodium sulfide (Na2S) or sodium hydrosulfide (NaHS).
