The Cu recovery of the tailings material from Taltal was high for both leaching techniques. With bioleaching around 70 % of the copper went into solution. This was substantially more than in the control experiment with slightly higher than 50 %. In the chemical leaching more than 80 % could be extracted.

1.0 TAILINGS LEACH PLANT, AN OVERVIEW From inception, Tailings Leach has been developed in three stages. The operation started with leaching of low-grade tailings using strong sulphuric acid followed by solution recovery and cementation of copper. The capacity then was about 1000 tonnes of copper per month.

15-06-2018  Some researchers have investigated the possibility of copper recovery from the tailings using bioleaching and atmospheric leaching [ 6, [26], [27], [28] ]. Since the bioleaching process is very slow and sometimes produces toxic chemicals [ 28, 29 ], most studies are focused on atmospheric leaching.
