  • Function Of Mine Geology Of Ore Production

    Function Of Mine Geology Of Ore Production. 2020-5-26Mine geologists study the relationship between geology and ore formation and locate new mineral resources. They are mainly responsible for assessing and analysing geological data in order to advise on short-term and long-term mine production plans.

The reason for describing this as a ‘mine geology system’ is that all components need to work together. It should be well understood and also communicated to other departments within a mining operation. The results are reduced if parts of the system are missing or carried out to a different standard.

  • Ore - Wikipedia

    2020-7-5  Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit.Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.. The grade of ore refers to the concentration of the desired material it contains.
