Bulk ore sorting and coarse particle recovery – leading the way in mineral processing innovation Anglo American is at the forefront of applying innovative technologies that are fundamentally changing the way minerals are processed – two of which are bulk ore sorting (BOS) and coarse particle recovery (CPR).

ore on electricity; an equivalent amount on grinding media in the SAG circuit alone; but only $0.30/t of broken ore on explosives at the drill and blast stage. Yet, the blasting process is a much more energy efficient method of fragmenting rock. The need for energy efficient processing is becoming increasingly important as we continue

Bulk Ore Broken In Mining T02:06:00+00:00 Bulk Ore Broken In Mining. Shrinkage stoping is a mining method used for steeply dipping, narrower ore bodies with self supporting walls and ore It is an overhand mining method that relies on broken ore being left in the stope to be used as the working floor and to support the walls During the ...

Preconcentration through bulk ore sorting has the potential to benefit all these areas by enabling mining operations to divert material of low economic value prior to processing, …

Broken ore remaining in the mine may have been subject to enhanced milling during the mucking process, yielding enhanced liberation of the economic …

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.

Bulk ore sorting offers the potential to either delay or wholly eliminate the need for this capital spend while also ensuring that high grade material is delivered to the mill. The increased recovery and profitability …

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.

Bulk ore sorting, a preconcentration technique applied to bulk streams or large volumes of broken rock, has gained particular interest from mining companies.

The same excavation in feet: Excavated area is 200 feet long 20 feet wide and 2 feet deep with a listed swell of 40% for the material. Bank volume = 200 * 20 * 2 = 8000 ft³. Convert 8000 ft³ to yd³ = 8000/27 = 296 yd³. Loose volume = 296 * 1.4 = 414 yd³. (Calculations are based on the material being of similar consistency.

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 …

The Broken Ore Density (referred to by its acronym BOD in the remaining paper) is the ratio between the bulk weight and volume of the caved ore in the draw column. Several related parameters that are more easily assessed have been proposed in the literature based on the volume of caved rock ( V caved ) relative to its undisturbed in …

Abstract. The tonnage factor or average in-place bulk density of the orebody is one of the most important variables in the calculation of the weight of product to be expected from a proposed mining operation. Errors in the determination of the in-place dry bulk density upon which the tonnage calculations of a deposit are based may completely ...

Bulk ore sorting (BOS) has the potential to reduce processing costs and improve mine economics. A factor that impedes its acceptance is the lack of a method to assess ore amenability to sorting. In this study, a fractal model of metal distribution was used to assess an ore's bulk sortability. A BOS model was developed where metal …

In this sense, bulk ore sorting was sometimes referred as 'selective mining'. Bulk ore sorting is also considered as a pre-concentration technology, a concept in 'processing'. It should be noted that bulk ore sorting was different from the commonly noted particle sorting where ore particles of a narrow size were one-by-one sorted based ...
