Process Mineralogy
The treatment of auriferous ores presents several challenges to the metallurgists and plant operators due to there are some factors that have an important impact on the process. Without any doubt the mineralogy is the key aspect of the process performance. Basically, there are several options to be considered at the moment of evaluate the […]
Mineralizers
Combining mineralizers and a group of minerals which it has been impossible to synthesize by the open fusion method, as there is contained in their molecule small amounts of volatile compounds as fluorine, water as hydroxyl, or chlorine; or again the fusion at the point or temperature of crystallization is so viscous as to prevent […]
Geometallurgy Course & Geometallurgical Modelling
Basic Geometallurgy Short Course for mineral processing applications Geometallurgy and grinding It is often desirable to be able to load ore hardness information into the mine block model. Allows the mining engineers to better schedule ore delivery to the plant, and to run more sophisticated net present value calculations against ore blocks. Requires hundreds of samples from […]

Gravimetric Factors
The factors used to convert metal assays to mineral assays in this MVT Mississippi Valley Type Deposits review is summarized below. The conversion factors are based on standard metal to mineral gravimetric factors with some minor adjustments to compensate for the interstitial iron contained in the sphalerite lattice. The measured value for interstitial or submicroscopic […]
Stereological Corrections
In reflected light mineralogical studies involving opaque minerals, it is possible to section a composite particle so that the particle appears to be liberated. Clearly, a binary particle may be sectioned to appear liberated but a liberated particle cannot be sectioned to appear locked. The probability of this former occurrence depends upon the relative amounts […]
Rare GOLD Minerals
This list of ores classified as natural and rare gold minerals are refractory to process. All these are sulphides refractory gold bearing minerals and will have a poor response behaviour to usual cyanidation extraction methods, and for the little guy, best used for exhibit or sold to rock collectors on eBay. Native Gold Au Formula Muthmannite Very Rare […]

Gold Prospector – Mineralogy and Microscopy for Prospecting
Small Gold Prospectors, Miners and Processors needing simple DIY mineralogy or microscopy work can take advantage of the fact that a gold shaker table behaves as some kind of a classifying device and view their gold sample directly under a microscope without all the preparation work. You can take any of your Prospecting products and look at […]
