measurement at 0.02% Cu precisions. Some are for bulk ore sorting with others for evaluating 30 second measurement data to understand ore variability in real time including for feed forward control. Scantech has experience using GEOSCAN-M in bulk ore sorting of iron ore going back to 2008, where a third of a site's product is diverted to bypass
Capable of sorting thousands of tonnes of run-of-mine or primary crushed ore per hour without screening or washing, delivering bulk grade measurements within seconds. Real-Time Tracking Providing ore grade readings in real-time, enabling mine operators to autonomously control downstream 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 on sensor measurements. In comparison to particle ore sorting, bulk ore sorting is advantageous with a large treatment capacity and lower unit capex/opex(Klein and Bamber, 2019).
Determining bulk density from larger samples Bulk samples may be obtained if trial mining or production is already in progress at a site. The in situ volume of bulk samples can be …
The bulk and channel samples grades were back-calculated to a 1.5 m mining width. The lowest vari ability is displayed by the bulk samples, with an RSV of 73% and nug get effect of 48%.

Additionally, bulk ore sorting can reduce dilution and ore loss in mining operations by improving grade control. In some cases, mining costs may be reduced, with the bulk ore sorter providing
The procedures for conducting bulk density tests is out lined as under: 4. Bulk density tests Table.1. Bulk Density Test for Iron Ore at Obulapuram Iron Ore mine dated 20-6-2014 Average Bulk Density: 2.98+3.02+3.03+2.51=2.88 Pit No.01, Pit No.2, Pit No.3 and Pit No.4 were considered for conducting the bulk density determination test work.

THE Broken Hill mining field, approximately 31 miles in length, is at present being exploited by seven companies, viz. : North Broken Hill Limited, Junction North Broken Hill No Liability, Broken Hill Proprietary Block 14 Company, Broken Hill ProprietaryCompany Limited, Sulphide Corporation Limited, Broken Hill South Limited, and Zinc Corporation Limited.The variation in …
•A bulk ore sorter ensures correct allocation of ore and waste. • May also reduce quality control requirements at bench level. - Potentially increasing mine productivity and reducing costs
The broken ore density (BOD), commonly related to the swell or bulking factor, is an important parameter for block caving design. It is well known that the ore column density decreases (and swell ...
If a drift or crosscut is timbered to the breast, because of heavy ground, floors are laid on sills or spreaders; if untimbered, turn sheets of ¼-in. steel plate are placed against the breast to receive the broken ore. About 70 per cent, of the ore broken in drifts is shoveled from floors or turn sheets, the remainder from the rough bottom.
The broken ore density (BOD), commonly related to the swell or bulking factor, is an important parameter for block caving design.
In this paper, to reveal the flow characteristics of broken mineral-rock of block caving, we present the Attribute Stochastic Medium Theory that combines an attribute block model with stochastic medium theory. An attribute …

Sampling is a critical component throughout the mine value chain; it includes the sampling of both in-situ and broken material for geological (resource and grade control), geoenvironmental, and geometallurgical purposes [1,2,3,4,5,6,7].Sampling errors generate both monetary and intangible losses [3,8].The data produced must be fit-for-purpose in order to …
Bulk mining methods are fully mechanised allowing the excavation of large volumes of ore. These techniques enable high production rates in underground mines, but are less effective in separating ore and waste so are …
Suppose this lot to be subjected to a slight crushing and the solitary piece of mineral broken into three fragments, then dividing the lot into halves would at the best throw 50 per cent, more value into the one half than into the other; it is therefore clearly manifest that in order to obtain a sample which shall correctly represent this or ...

Sublevel shrinkage (SLSh) is an underground mining method similar to sublevel caving (SLC) but with continuous backfilling from the top. It features a top-down mining sequence with production drifts orientated in a longitudinal or transverse way in the orebody. Fan drilling and blasting is done from the production drifts, from where the ore is then drawn. While drawing, …
Bulk ore sorting could also be used to reduce dilution and ore loss in mining operations by improving grade control, or to separate ore types to treat via different process routes. ...
To extract copper from ore broken near Dolgellau, North Wales, c 1898 Frank Elmore developed a technique of selectively transferring minerals from water into oil. Frank and Stanley Elmore began to exploit bulk-oil flotation internationally, but soon alternative schemes emerged in Australia and Europe and the brothers became involved in damaging litigation with …
