Abstract. The identification of the procedure and instruments to carry out a preliminary evaluation of the possibilities of a crude ore beneficiation, starting from the exam of a considerable number of samples, has been carried out since ever, through the setting of comminution models, that can foresee, besides the granulometric distribution of products, also their composition.Minerals Special Issue : Mineral Liberation,The extent of mineral liberation is a determining parameter to define the optimal comminution process in order to obtain the maximum grade during the separation process with the lowest energy consumption. In addition, knowing what minerals accompany the ore is necessary for applying separation techniques.Changes to Pilbara Ore Reserves and Mineral Resources,2019-11-11 · Changes to Pilbara Ore Reserves and Mineral Resources . 2. March 2018 . Rio Tinto’s 2017 annual report, released to the market today, includes significant changes in estimates of Ore Reserves and Mineral Resources for four Pilbara iron ore deposits in Western Australia compared to,the previous estimates in the 2016 annual report.
Further to a geological evaluation done from a borehole, the deposit is accessed by the main ramp. Then, for a same level, many ore drifts are developed to delineate the vein. When the definition is completed, the geological model is revised and planning of the production drilling is done. Longhole drilling is performed with upholes.Long hole nvp-pgf,Long hole.
