Geometallurgical models creation principles

Abstract

The following article explores the aspects of geometallurgy model creation and its position in the general chain of geological and technological mapping. The following article describes the model creation process and principles applied in the framework of different approaches to geometallurgy model creation. Currently, this type of modeling is considered the most important and reliable tool for forecasting the technological and economic performance of mining companies. The most progressive is the approach based on the use of quantitative mineralogical analysis for geological and technological modeling, which is very labor-intensive and requires modern and expensive equipment. An approach is being developed in the Russian Federation that is based on the transformation of a geological database into a technological one. The article discusses the algorithm for creating geometallurgy models, which includes several components: exploration, mineralogical and petrographic, technological, statistical, geostatistical and economic. The most important points of modeling are studies to identify the factors that determine ore processing and criteria for ore typification, which ultimately leads to the development of principles for recognizing types of ore in each geological sample. It is in this way that the geological database is converted into a geological-technological database, and a geological-technological model is created on its basis.
