Chalcopyrite (Cu) Sphalerite (Zn) Separation by Flotation
The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present. This is usually the case in ore deposits near the surface or in tropical countries where the annual rainfall is quite high. The method of ore deposition is also a fact…See more on 911metallurgist

Handling underflow in a Gaussian Naive Bayes classifier
I am implementing a Gaussian Naive Bayes classifier (so each feature is continuous and assumed to be coming from a Gaussian distribution). When evaluating the probability of a feature value in the test set, if the value is sufficiently far away from the mean (e.g. the mean and s.d. on the training data is say 0 and 1 but the test value is …

Chalcopyrite | Common Minerals
Chalcopyrite is a soft mineral that can be scratched by a nail, while pyrite is hard enough that a nail cannot dig into its surface. Unlike pyrite, chalcopyrite also weathers to display an iridescent tarnish. The two minerals also usually occur in different forms. Pyrite is most often found as crystal masses that exhibit obvious flat planes and ...

Chalcopyrite
Chalcopyrite is a copper iron sulfide (CuFeS 2) mineral with a brassy to golden yellow color (Fig. 1.36). Chalcopyrite contains 34.5% Cu, 30.5% Fe, and 35.0% S. The mineral is the principal source of copper metal, and one of the major source of sulfur. The mineral also contains traces of elements of gold and nickel and recovered in refinery.
