Surface Mining Sustainable Development & Environmental

Surface Mining. Author: Alan Cluett ~ Environmental Consultant, Holcim South Africa ( Article Type: Explanation) Mining, by its very nature, is not sustainable into the future. Through the process of mining, finite natural resources, in the form of minerals, are extracted from the Earth’s crust, beneficiated and consumed by our society.

Diamond Mining Methods Diamond Museum Cape Town

There are two types of pipe mining, namely open-pit mining and underground mining. the kimberlite pipe that reaches the Earth’s surface is eroded and weathered by wind, rain, rivers and streams.The eroded kimberlite bears rough diamonds, which are carried downstream. The first diamonds discovered in South Africa were from alluvial deposits.
