Evaluating the Applicability of Gold Pre Concentration by
Jan 01, 2017 Therefore, in order to sort gold ore, properties of associated host rock are used. Free and sulphidic gold is often hosted on the quartz-host rock contact zone. Laser scattering effect can be used to detect the surfaces of quartz and composite quartz-host rock particles for subsequent sorting with very high recovery of 95 to 99%.
Sorting the future Possibilities at Obuasi Mine CEEC
Added advantages of the strategy includes faster recovery of gold from the quartz stream, with less consumption of reagents from saving on flotation and BIOX reagents for this stream. Screening and Ore sorting was successfully tested with laser technology, achieving over 98% separation of quarts (containing up to 40% of the gold).

Performance evaluation of optical sorting in mineral
Alongside with the evaluation of change in sorting performances in accordance with feed rate, ore type, and particle size; pre-concentration of copper and gold ores, concentration of hematite from alkaline waste, dry cleaning of lignite and market quality magnesite and quartz sorting applications with VIS type optical sorter were also discussed.

May 07, 2019 type characterisation. Planned further ore sorting testing will target known mineralised intercepts to determine potential increased grade pre-concentration through ore sorting. Grade increases are expected with ore sorting as the gold is known to be almost exclusively hosted in the quartz-sulphide veins based on detailed core samples and

Measurement data is used concurrently for various applications: bulk sorting, ore blending, ore reconciliation, ore tracking, feed forward control, metal accounting, etc. “GEOSCAN GOLD is the new standard in representative, real time, conveyed material measurement using Scantech’s Rocks2data customisation module,” the company said.
Where are Gold Deposits in Canada
Oct 05, 2016 Placer deposits of gold are formed by the concentration of the gold from the debris of gold veins and other deposits of gold in rock. As the loose material is washed down hillsides into gullies and valleys, the gold, being six or seven times as heavy as quartz and other rock- minerals, quickly works its way to the bottom of the moving mass and ...

Ore sorting Efficiently optimise the treatment of ores in
Gold. In southern Africa, two x-ray sorters are used to pre-concentrate sulphide gold ore into two different grain size categories. While the input material has an average gold content of less than 0.8 g/t, the sorted product achieves a concentration of more than 4 g/t with an efficiency of approximately 90%.
Minerals Free Full Text Sensor Based Ore Sorting
The first one is the Quartz-associated Gold ore, where a high recovery of (surface visible) Quartz leads to a high Gold recovery. It showed that the detection of small Quartz veinlets was especially important for a high Gold recovery because of the Gold mineralization in close vicinity to the veining—even more than in the Quartz veins themselves.
COREM Steinert ore sorting tests present opportunities
Apr 09, 2021 Cartier Resources says ore sorting tests carried out by COREM and Steinert US on mineralised samples from the Chimo Mine property, in Quebec, Canada, have indicated gold grades could increase substantially with the use of the pre-concentration technology. Gold from Chimo is present in two types of mineralised facies: i) quartz veins with coarse visible gold grains having an affinity for the gravity concentration of gold …
