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 postmining revegetation of the site. Next the top soil is removed and is usually also stored for replacement during rehabilitation.
