Kimberlite
Kimberlite is an igneous rock and a rare variant of peridotite. It is most commonly known to be the main host matrix for diamonds. It is named after the town of Kimberley in South Africa, where the discovery of an 83.5-carat (16.70 g) diamond called the Star of South Africa in 1869 spawned a diamond rush and the digging of the open-pit mine called the Big Hole. Previously, the term kimberlite The objective of this paper is to illustrate some of the mining problems that could arise if the kimberlite emplacement model is flawed or poorly understood.

Arctic Canadian Diamond Company and IHC Mining Jointly
As the URM crawler is only mining the kimberlite ore and minimal waste, it significantly reduces the mine’s footprint. The URM solution could allow the Ekati Diamond Mine to extend its lifetimeArctic Canadian and IHC Mining started their cooperation in 2018, to jointly develop an innovative and integrated mining solution. This so-called underwater remote mining (URM) system consists of a floating platform, an underwater mining crawler and a land based dewatering plant.

Mining Diamonds in the Canadian Arctic: The Diavik Mine
Four kimberlite pipes occur in close proximity—three are being exploited, while the fourth will be brought into production in 2018. Diavik is now expected to operate through 2024; upon closure, the equipment, buildings, and infrastructure will be removed and the land returned as closely as possible to its original condition. INTRODUCTIONHere's a step-by-step guide to how a room and pillar mine is developed. 1. Exploration. First, a deposit must be identified and determined as suitable for this technique. Coal, iron, and uranium are among the most common materials extracted using this method.Beginners Guide to Room and Pillar Mining An Underground Miner

Equipment. Polysius was commissioned to supply equipment in 2008. The company commissioned a high-pressure grinding roll and a scrubber for disagglomeration at the mine in 2008-09. The A secondary crusher, known as a roll-crusher, may also be used to reduce the size of the ore even further. Stage 2 Scrubbing. In this stage, the ore are scrubbed to remove loose excess material and is screened. Material smaller than 1.5mm is discarded because it is too costly to extract diamonds from such a small piece of ore.Diamond Mining Methods Diamond Museum Cape Town

Mothae Diamond Mine (Lucapa Diamond Company) Lesotho
The trial mining resulted in the production of more than 600,000 tonnes (t) of kimberlite and recovery of 23,000 carats (ct) of diamonds. Lucapa Diamond Company, based in Australia, acquired the Mothae project from Lucara in January 2017. It was also issued the mining license for the project in the same month, which is valid until January 2027.Lace is a historic mine, with operations spanning back to 1896. Its mineralisation consists of a diamondiferous kimberlite pipe built to a depth of 240m. The first mining operations were started in 1901 and it was operated until 1931. It became obsolete with the Great Depression and the fall of diamond prices in 1930.Lace Diamond Mine (LDM), Kroonstad, Free State, South Africa

Cecil Rhodes and his colleagues begin efforts to consolidate the separate individual mines under the control of one company in 1887.Mining options for a steeper slope cost versus values. There are at least three mining options for a steeper slope angle. One obvious option is to save mining costs by mining less waste for the same amount of ore on the shallower slope, as illustrated in Figure 8.Design and implementation of steeper slope angles on a kimberlite
