The mine is a company which mines gold along the great dyke. Currently, the process involves passing the stones through a jaw crusher (14x16 inch). The products are then sent to a twin deck screen which is 25mm top screen and15mm bottom screen. Screen oversize are then sent to a 36 inch cone crusher running on a closed operation.

Crushing Plant Design and Layout Considerations

Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine’s trucks, then operators must slowly meter the ore into the receiving hopper.Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mine/shovel operations.

The diamond mining life cycle - Mining for schools

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 approximately 45,000 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.
