Selective Mining
Selective mining refers to a mining technique where specific ore bodies or mineral deposits are targeted for extraction, rather than extracting and processing all available materials from a mining site, then wasting out of specification material after processing. This process involves making determination in the pit or underground as to where the soon to be extracted material will be sent, processing plant or waste dump, as opposed to processing, then wasting out of specification product. This approach is often employed to optimize resource utilization, reduce waste, and minimize environmental impact.
- Thorough geological and geophysical surveys are conducted to identify and characterize ore bodies accurately. This involves understanding the composition, size, shape, and distribution of valuable minerals within a deposit.
- In many cases, the above mentioned initial ore body characterization that is done during the exploration phase of mine development may not be refined enough to be of daily practical use. As such, additional geological data must be captured while mining and incorporated into the geological ore body model, to drive short term mine planning needs.
- Excavation mining equipment is used to extract and blend ore at the mining face or at the primary crusher. This not only improves the production of in specification final product, but also makes use of potentially marginal ore blended up, to maximize the value of the deposit.
Selective mining aims to maximize the recovery of valuable well blended resources while minimizing the extraction and processing of waste material. This improves the overall efficiency of the mining operation and reduces the environmental impact associated with the disposal of off specification products.
