Gold Ore Processing " ScienceDirect

More importantly, gold in an ore may occur in two or three forms (i.e., microscopic gold, submicroscopic gold, and surface gold), making gold ore processing extremely challenging. The objective of gold geometallurgy is to reduce and minimize the technical risk in project evaluation, plant design, mine planning, and production forecasting through geometallurgical modeling, representative sampling,

Designing gold extraction processes: Performance

Gold mineral type, referring to the most general description of the ore, such as “Free milling” or “Silver rich”, and gold concentration, or Gold ore grade, were relatively straightforward to model into attributes. Other valuable minerals, such as silver, were not seen being as characterising as gold with regards to process design and profitability. Overall mineralogical composition is also important, but significantly

Mineral resource estimation Wikipedia

Resource estimation is used to determine and define the ore tonnage and grade of a geological deposit, from the developed block model. There are different estimation methods (see below) used for different scenarios dependent upon the ore boundaries, geological deposit geometry, grade variability and the amount of time and money available.

Model for heap leaching of gold ores by cyanidation

The objective of this study is to develop a model which describes the heap leaching process for gold extraction from non-refractory ores. The model considers the cyanidation reaction in a bed of uniformly sized spherical porous mineral particles, through which the leaching solution trickles.

Gold Units: Is there enough gold present in the ore to pay for the costs associated with recovering it? Depending on all the other variables and costs associated, some projects can be viable with a gold grade as low as 0.5 g Au per tonne of ore, with sufficient tonnages. With lower gold grades beneficiation (usually flotation) is often used ahead of leaching to increase the grade of Au and reduce the quantity

The ore body can then be modelled automatically using interpolation software with isosurfaces indicating the regions with highest probability of gold mineralisation. A good understanding of the geological features associated with mineralisation and consistent geological logging are important prerequisites for successful conditional probability modelling of drill hole data.

The leaching and adsorption behaviour of gold ores

The effect of processing the oxide and sulphide ores studied was examined and the model shown to satisfactorily describe the extraction of gold from the Telfer oxide ore. A sensitivity analysis of the effect of process changes on this ore was then undertaken, where the correct operating response to preg-robbing ores and process changes were determined.

Gold distribution in vein-hosted hydrothermal ore deposits is commonly nuggety (i.e. occurs as very localised concentrations of gold). In these cases samples for gold assay from diamond drill core may be too small to model the underlying heterogeneity of gold distribution and result in poorly constrained ore body models and underestimated gold resources.
