  • Innovations: Newly Mined Copper: Why Do We Need It?

    Copper scrap is important because it reduces our reliance on newly mined copper. Its use also helps reduce energy consumption and the emission of greenhouse gases. We can''t utilize copper scrap for all products, but thanks to its high value and easy recyclability - plus the help of an efficient recycling industry - every available bit of it is put to appropriate use.

  • Mining and Refining – Process

    Before mining can commence the land needs to be cleared of timber and vegetation. Alongside this process may be the collection of seeds and/or saplings, for inclusion in a seedbank, which will form the basis of post-mining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
