The 5 Stages of the Mining Life Cycle Decipher

Apr 29, 2019· The final step in production is smelting; this process involves melting the concentrate in a furnance to extract the metal from its ore. The ore is then poured into moulds, producing bars of bullion, which are then ready for sale. 5. Closure and reclamation. The fifth and final stage in mining operations is closure and reclamation.

Lifecycle of a mine: a step-by-step guide to mining

The amount to be produced each year dictates the life-of-mine (LOM), which estimates how many years it can economically produce for. However, many companies have shut mines earlier than planned because the economics became unfavourable, or extended the LOM at some point as new resources and reserves are found, such as a nearby satellite deposit

The diamond mining life cycle Mining for schools

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. Venetia mine is an example of open-pit mining.
