The Leachox™ Refractory Gold Process – The Testing,

2019-5-14  The Leachox refractory gold process has to date been applied to the selectivetreatment of several refractory gold ores but on a relatively small scale. In this paper the successful implementation of the process, from initial testing through to commissioning at one of the world’s largest refractory gold mines is described.

KAZ Minerals Focused on copper

The ore is processed through a series of crushers and mixed with water. This produces finely ground ore in the form of a paste or slurry. The slurry is mixed with various chemical reagents that can identify and coat the specific mineral particles. A liquid ‘frother’ is added to aid the separation process.

Mineralogy and Pretreatment of a Refractory Gold

The gravity–flotation combined beneficiation pretreatment process provided a feasible method for the refractory gold ore and ensured the effective recovery of gold. The technological mineralogy of a gold deposit located in North-Western province of Zambia was carried out by using X-ray fluorescence spectroscopy (XRF), X-ray diffraction spectroscopy (XRD), and scanning electron microscope (SEM).

Ore sorting - Preceding processing Ausenco.

2019-3-4  Place the ore sorter in the wrong place and the separation efficiency is nowhere near as high as it could be. Metso explained: “Most mining deposits are naturally heterogeneous and lend themselves well to bulk ore sorting, but it should be implemented as early in the process as possible before excessive mixing occurs. Material presented to the sorter needs to have sufficient grade variability occurring in large enough batches of material for effective separation.

Comparative investigations on sulfidic gold ore

2019-8-15  The calcine was used for bottle roll cyanidation leach tests. The sulfide oxidation from all three temperatures were over 99.5%. Gold and silver extractions from the roaster calcine was summarized in Table 8. The gold extraction was 44.4% after roasting at 500 °C and it increased to 60.0% and 70.2% at 650 °C and 800 °C roasting, respectively.

Mineral Processing – McClelland Laboratories Inc

A Knelson or Falcon concentrator is designed to process fine, free gold that does not require cyanidation for recovery. These use the principle of centrifugal force which aids in the separation process based on the particle density. In the laboratory, these generally are operated as batch processes but can be made to operate continuously.
