The main purpose of geometallurgy is to develop a model to predict the variability in the mineral processing performance within the ore body. Geometallurgical tests used for developing such a model need to be fast, practical and inexpensive and include as an input data relevant and measureable geological parameters like elemental grades, mineral grades and grain size. Important in each geometal...

A geometallurgical model was developed in three steps using the Malmberget iron ore deposit, northern Sweden as a case study. It is based on a mineralogical-particle approach which means that the mineral information is in the focus. Firstly, the geological model describes quantitatively the variation within the ore body in modal composition and mineral textures. Traditional geological textural ...

Comminution tests are an important element in the proper design of ore beneficiation plants. In the past, test work has been conducted for particular representative reference samples. Within geometallurgy the entire ore body is explored in order to further identify the variation within the resource and to establish spatial geometallurgical domains that show the differential response to mineral ...
