Simulation of Weathered Iron Ore Facies: Integrating Leaching Concepts and Geostatistical Modelszil. Weathering may reach 500 m in depth. An important issue in supergene iron modelling is the evaluation of the boundaries between the high-grade soft ore, partly enriched itabirite and protore..A simple numerical model has been developed in order to simulate a leaching system in a two-dimensional

Geostatistical Framework for Modelling Clay Deposits: Nova Veneza Case Study in Southern Brazildients in the ceramic industry. Clay characteristics including several physical and chemical parameters need to be known throughout the entire deposit to help in defining the mining plan, scheduling and blending strategies..This paper proposes a geostatistical framework to model two essential clay p

Evaluation of Kriging and Cokriging for Asbestos Ore Reserve Estimation at the Cana Brava Mine, Goiálopment of this mine more than 1000 vertical diamond drill holes were completed on a regular 35×35 m. grid. Representative samples from mineralized zones were analysed for total grade (TT), long fiber grade (TL), medium fiber grade (TM), and short fiber grade (TC), as well as the grades retained on
