Abstract. In several process industries including mineral processing, where the materials are solids or slurries, some important measurements cannot be obtained using standard instrumentation (e.g., flow, temperature, pressure, pH, power draw, etc.), but can be visually appraised, and could be automatically quantified using machine vision techniques.

Mineralogical analysis is the study of materials to determine mineral composition and mineral structure. This analysis can be used to identify mineral species, and understand their characteristics and properties. At Lucideon, we offer a wide range of mineralogical testing, much of which is accredited under ISO 17025:2017.

Le broyage est l’une des étapes les plus coûteuses de l’enrichissement et produit comme résultat de très fines particules qui facilitent une meilleure extraction du métal. Toutefois, le broyage per-met également un dégagement plus complet des contaminants lorsque ces particules deviennent des résidus.

As it is a cumulative size distribution, the horizontal axis is a superior limit, i.e. the mesh opening through which the particles in a sample can pass. It is clear how both mineral species distribute mostly in the finest fractions of the ore. The total mass of every mineral contained in every size is observed regardless of its liberation degree.

A faultless and comparable analysis is closely linked to an accurate sample handling. Only a sample representative of the initial material can provide meaningful analysis results. Rotating dividers and rotary tube dividers are an important means to ensure the representativeness of a sample and thus the reproducibility of the analysis.

The Mineral Liberation Analyzer (MLA) is an automated mineral analysis system that can identify minerals in polished sections of drill core, particulate or lump materials, and quantify a wide range of mineral characteristics, such as mineral abundance, grain size and liberation.
