pit to crusher stockpile techniques

  • PIT-TO-PLANT OPTIMISATION AT MORILA GOLD MINE

    Run-of-Mine (ROM) ore is transported directly from the open pit in 90 tonne payload, CAT 777D haul trucks. This material is either stockpiled on the ROM pad or directly tipped into the primary crusher. The Nordberg-54/75 primary crusher reduces the ore down to less than approximately 300 millimetres in a single stage, open circuit.

  • How to track and control the Stockpile's mass inventory

    To have control over the mass transactions from the pit to the stockpiles and from the stockpiles to the crushers is usually a challenge, particularly for big mining operations. The brains.app Stockpile Mass Inventory dashboard provides you the right information to track and control how much material is being dumped to and reclaimed from each stockpile and subsequently fed to the existing crushers.

These include high-grade (>13% Zn), medium-grade (9 13% Zn), low-grade (4 9% Zn) and marginal (1 4% Zn) ore stockpiles. Limestone (Ca >28%) from the pit is mined for plant acid neutralisation purposes. Material with Zn <1% is designated for the waste stockpile.

    3/1/2018· Truck haulage is the most common method for bring material out of an open pit mine and to the process plant, stockpile or waste dump. As the mine life matures, the pit becomes deeper and waste dumps become bigger, resulting in increased truck haul cycles which requires additional trucks to maintain production rates.

    If the load is clean high grade ore, it will either be directly taken to the ROM (run of mine) pad at the Primary Crusher, or unloaded to a stockpile on Pad 12 for feed into the CSI Crusher. Waste rock is taken to a dump for storage, while low grade ore is taken to a stockpile for potential processing at the end of mine life if economic.
