Extraction of Copper from Malanjkhand Low-Grade Ore by

The increase of the temperature leads to an increase of copper extraction rates from low-grade copper ore as shown in Fig. 4. A maximum of 81.25% Cu was recovered at 60C as compared to other three temperatures i.e. 56.92% at 40C, 60.37% at 50C and 78.92% at 60C respectively. Copper dissolution was higher at 60C than at 50 or 40C.
