Numerical Experimental Study on Ore Dilution in Sublevel Caving Mining
On the basis of physical ore-drawing test research, the irregular particle clusters are constructed by adopting particle element theory and PFC numerical simulation software. Meanwhile, the ore dilution mechanism in the process of stoping caving ore and rock bulk is investigated, especially, the permeability characteristics of small size …

Bulk ore sorting improves profitability and sustainability
Bulk ore sorting could also be used to separate ore types to treat via different process routes, or to reduce dilution and ore loss in mining operations by improving grade control. It is an efficient way to deal with uncertainties of grade, particularly where the complexity of mine geology makes the estimation of grade difficult.

The quantity of ore mined and waste rock (i.e., overburden or barren rock) removed to produce a refined unit of a mineral commodity, its rock-to-metal ratio (RMR), is an important metric for understanding mine wastes and environmental burdens. In this analysis, we provide a comprehensive examination of RMRs for 25 commodities for …

Understanding ore heterogeneity and effective bulk ore …
An understanding of ore heterogeneity can be assessed using drill core data, which provides metre by metre elemental assays. This paper reviews such data and assesses the grade distributions over different scales, which suggests that sufficient heterogeneity exists at mining scales to allow the potential for bulk ore sorting.
