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. In underground mining
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. Venetia mine is an example of open-pit mining. In underground mining,miners tunnel into the earth’s crust through the kimberlite pipe.
Open-pit mining involves removing the layers of sand and rock found just above the kimberlite. 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
The mine planning process for an open-pit diamond mining operation the two pipes is shown in Figure 3. A 2012 resource extension drilling program has increased the confirmed vertical depth of the kimberlite pipes to 793 m and 828 m for the Main and Satellite pipes respectively (Figure 4). The surface expression of the Satellite Pipe is
Argyle operated as a conventional open-pit mine, with both lamproite and waste rock being drilled and blasted before being loaded out in a shovel-and-truck operation. The mine operated Bucyrus, P&H and Tamrock Driltech rotary drill rigs, O&K RH 200 hydraulic excavators, and a fleet of Caterpillar 789B and Unit Rig MT4400 haul trucks, supported
The Ekati diamond mine is approximately 300km north-east of Yellowknife, near Lac de Gras in Canada’s North-West Territories. It is Canada’s first surface and underground diamond mine.. Dominion Diamond (DDC) acquired the mine from BHP Billiton in April 2013 and was owned by DDC and Archon Minerals till 2017.
All kimberlite ore will be trucked and tipped into the primary crusher located 560m from the edge of the current pit. The front-end arrangement allows for direct tipping into a crusher tipping bin fitted with an 800mm aperture grizzley and rock- breaker. The crusher bin has a live capacity of 180m3 or approximately 320 tonnes.
Open pit mining is used to extract ore in rock bodies that are at or close to the surface of the Earth. Large‐scale equipment ‐drills, shovels, and trucks ‐are used to make operations efficient and economical. When they move in, the ore is dug up and sent to a mill for

Mining of a diamond-bearing kimberlite generally starts with the excavation of a pit into the kimberlite pipe. In this process, called ‘‘open-pit’’ or ‘‘open-cast’’ mining, the initially weathered ore material is removed with large hydraulic shovels and ore trucks.

Sep 05, 2017 large scale, open pit mining is used to extract diamond ore at argyle.broken ore is loaded onto tonne trucks for transport to crushers where it is reduced to fragments measuring millimetre or less.any diamonds larger than millimetres would be broken.
However, blasting capacity may present upside to the overall capacity of rock breakage and comminution leading to an increase in a mines ore throughput. In some projects reducing the ore top size specification allows an adjustment to the primary crusher setting resulting

The ore will be hauled from the pit to the primary crusher by 220-tonne dump trucks. The crusher will be located in the building closest to the pit to minimize haulage distance, in a place where it can be safely operated. The primary crusher will operate 65% of the time. It will be a 1.52 m x 2.26 m gyratory crusher that can crush up to 4,670 tph.
OPEN-PIT MINING Open-pit mining, such as the Kimberley Big Hole, involves removing the layers of sand and rock found just above the Kimberlite. The ore in the pit is then broken up by blasting. Once this ore is broken, it is loaded and then transported to a primary ore crusher where the diamond
Mining in the open pit is undertaken on 10 meter high benches. When the material is too hard to be free dug, the rock is drilled and blasted with a range of drill patterns to suit the litholog. The Open Pit is a conventional truck and shovel operation and is serviced by a large modern mining fleet of 175t and 90t haul trucks, loaded by 200t and
