Kennecotts millionton test heap The active leach program

The history and results of Kennecotts large-scale chalcopyrite leach program are presented. The program has now been underway for more than ten years. This paper describes the construction and active operation of the two-lift heap and the ancillary solvent extraction-electrowinning SX-EW pilot plant. The latter was used to recover the copper and provide a typical industrial raffinate for ...

Recently, HGI has been helping a copper heap leach facility in Arizona with its end-of-mine plans. A pilot scale injection project that included four deep rinsing wells and nine monitoring wells was tested to see if applying raffinate directly to ore under moderate pressures i.e., rinsing can increase liberation and eventual recovery.

for every kg of cyanide soluble copper extracted. Therefore, if the ore has 40 gt of cyanide-soluble copper, then the minimum quantity of cyanide required for copper leaching is 0.1 kg NaCNt. If the quantity of copper extracted increases to 300 gt then the cyanide requirement increases to 0.7 kg NaCNt. Viewed another way, since the 3 moles

0.3 Cu for copper oxide ore or strong leach solution pH of copper sulfide ore leach solution is 1.1 and pH of copper sulfide ore leach solution is 2. Column leaching results also show that about 80 to 90 of copper was recovered from the copper sulfide ore in a very short leaching time irrespective of crushing technique.
