In mineral deposit Secondary enrichment. An especially important class of residual deposit is formed by both the removal of valueless material in solution and the solution and redeposition of valuable ore minerals. Because solution and redeposition can produce highly enriched deposits the process is known as a secondary Read More

Once exposed the ore in the pit is broken up by blasting. A single blast can break approx. 3 000 tonnes of ore. Once the ore is broken excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process begins. The Kimberley Big Hole is an example of open-pit mining.

Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels called adits to reach the ore. Underground mining is however relatively expensive and is generally limited to rich ores.

The supergene enrichment of gold in deposits may take place by a simple mechanical process by chemical means or by a combination of these. First the enrichment may be primarily the result of the
