Semantic Scholar extracted view of "Explicit and implicit geological modelling methods on resource definition and resource utilisation-sishen iron ore deposit case study" by J. Deacon
ABSTRACT. The consumption of iron ore has increased rapidly over the past decade due to the tremendous growth of the iron and steel industry. The depletion of high-grade iron ore resources makes it inevitable to utilise the existing low-grade iron ores/fines/tailings with proper beneficiation to meet the present specification and demand.
