Ore and waste rock are mined by excavators loading onto trucks. In the open pit the trucks take their loads to the primary crushers or to stockpiles. In the underground mine the ore is taken to stockpiles at the processing plant, while waste rock is stockpiled for reuse as backfill once mined areas are completed.

2018-6-22  The mining process is responsible for much of the energy we use and products we consume. Mining has been a vital part of American economy and the stages of the mining process have had little fluctuation. However, the process of mining for ore is intricate and requires meticulous work procedures to be efficient and effective. This is why we have

Aggregate and mining industries process of millions

Mining and Aggregate industries process of millions of tons of rock every day. On site heavy machinery, loaders and conveyors take the rock to the plants for processing through crushers, shakers, screeners, blenders/sifters, and more. Mining and aggregate production is dependent on process metals and minerals, coal and shale, and rock for use

Excavating the rock Waihi Gold

The definition of ore and waste rock depends on the cut-off grade. If the cut-off grade is one gram per tonne (1.0g/t) all rock with more than 1.0g/t of gold will be marked out as ore while all rock which contains less than 1.0g/t of gold will be marked out as waste rock. The cutoff grade can be as low as 0.75g/t.
