Mineral resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model. There are different estimation methods used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.

13/07/2016 · The CIM Standards on Mineral Resources and Reserves – Definitions and Guidelines, the mineral resource reporting code required for Canadian projects by Canadian National Instrument (NI) 43101, states that a compliant mineral resource must be in "such form, grade or quality and quantity that there are reasonable prospects for eventual economic extraction". One of the [.]
The mining districts loed in the western mountain range in the south of Ecuador have gold minerals with refractory characteristics, which do not allow gold recovery by traditional methods used in Ecuador. Therefore, it is necessary to apply some technology that permits to obtain greater metal recovery. Biooxidation, as treatment of refractory ores that contain low grade of gold, offers an ...
