Tuwu Copper Mine is the largest mineral resource in Xinjiang. Due to the geographical and climatic conditions in the region, to date this resource has not been well exploited. Since 2010, the authors have been investigating the practicability of heap leaching for easy and effective copper recovery. The paper describes metallurgical studies and pilot plant tests conducted on Tuwu low-grade copper oxide...
This work reports the results about the determination of mean activity coefficients and relative partial molar free energies for copper sulfide mineral bioleaching solutions by potentiometric method at 25 °C. The experimental potentiometric data were obtained by combining a diamond film—cupric ion-selective electrode (Cu(II) ISE), containing a KNO 3 filling solution, and an Ag/AgCl electrode...
