2019-10-28 While the earliest form of marine diamond mining laboriously required a swimmer to collect gravel from a shallow seabed, modern technology granted access to greater depths through horizontal and vertical marine mining. Horizontal marine diamond mining uses a crawler to suck gravel from the ocean floor to the surface via flexible pipes, while vertical diamond mining

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. In underground mining, miners tunnel through Earth’s crust to the kimberlite pipe. Tunnels are constructed in two levels, one above the other with

2018-10-17 The extractive industry employs a range of techniques for mining diamonds, starting with conventional open-pit operations. The world’s largest mine, the Debswana-owned Orapa project in Botswana, uses open-pit mining to extract diamonds located up to 250m below the surface.
Read MoreWater, streams and rivers are the main drivers in the formation of secondary mining deposits as they can transport rough diamonds away from Kimberlite pipes to locations as far out as the ocean. Another mining method that is frequently used is called alluvial mining.

Marine mining involves extracting diamonds from the seabed, deep under water. Ships with specialised technology are used to mine for diamonds deep out at sea by using a powerful crawler that sucks gravel on the seabed up through flexible hoses or pipes.

Diamond ore is extracted from these mines using basically four mining techniques which are based on the type of geology in which the diamond bearing material is located. Marine Mining is the most recent development introduced about 1990. This technique is similar to deep water oil drilling. A large shaft is bored into the seabed to a depth ...

Here are a few examples of how the most popular diamond mining techniques wreak ecological havoc. 1. Marine mining, commonly practiced today, deploys large ships with powerful pipes that often drill deep into the seabed to reach diamond deposits. The pipes indiscriminately suck up everything in their path, displacing and disrupting the sea life.

Alluvial mining involves the building of walls and the diversion of rivers. Once the water is emptied out and prevented from flowing into the area of interest, bulldozers are then used to exploit the ground of the riverbank. Usually, kimberlite ore can be found in depths of at least 15 meters. When the diamond
