Diamond Mining in South Africa. The very first diamond discovered in South Africa was found in Hopetown on the banks of the Orange River and diamonds were initially mined from alluvial deposits found in such riverine areas. In later years, underground mining and recovery of diamonds became the more common method of diamond extraction. By 2019 ...

Diamonds are often found in the gravel layer, which collects under layers of other material, such as mud, clay and underwater plant-life.

Modern Platinum Mining Techniques. Most of the mining for platinum ore occurs deep underground. To extract the mineral-rich materials, miners pack explosives into holes drilled in the rock and blast it into smaller pieces. The broken rock is then collected and transported to the surface for processing. Platinum production in South Africa.
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
