Mining and Refining – Process - World Aluminium

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.


In response to global increases in metal commodity prices, the low grade base metal and precious metal ores (<1% copper, <1g/ton gold, < 0.5% nickel) previously considered uneconomical, became feasible with introduction of heap leaching technologies (Marsden, 2009).

Ore Grade Reconciliation Techniques – A Review

The essence of ore grade reconciliation is to identify, analyse and manage variance between planned and actual results in a way that highlights opportunities. A consistent record of poor reconciliation is an indication that this variance has not been adequately managed. This would inevitably result in significant economic impact on mining companies.
