Copper production is resource-intensive and we aim to avoid related environmental damage at every stage of the mining lifecycle. Our licence to operate relies on us fulfilling the requirements of environmental permits, and we seek to further reduce our impacts where possible. Doing so helps us manage financial, regulatory and reputational risks to our business.
KAZ Minerals is continually seeking to reduce the impact of its activities on the environment. Our business is changing rapidly as we have entered a period of significant expansion, with compound annual production growth of over 50% expected between 2015 and 2018 as we ramp up our major growth projects. 2016 is the first year in which Bozshakol and Aktogay made material contributions to the Group’s output, increasing total ore processed to 15.7 million tonnes, compared to 4.6 million tonnes in 2015. Energy use per tonne of ore processed fell from 0.86 TJ to 0.46 TJ, demonstrating the improved efficiency of the new mines and their modern equipment.
Energy intensity (TJ total energy consumption per kt ore processed)
The efficiency of our operations should improve further, both on a per unit of ore processed and per unit of finished metal produced basis, as the recently commissioned plants increase recovery rates and reach design capacities in 2017 and 2018.
