Quantitative automated mineralogy to constrain metamorphic processes using ZEISS Mineralogic
2020<p>The Scanning Electron Microscope (SEM) is the most prolific piece of analytical equipment in the Earth Sciences, therefore quantitative mineral chemistry obtained directly from the SEM has the potential to streamline many geological fields.

Process mineralogy of roasted pyrite and arsenopyrite
JOM, 1992Process mineralogical techniques can provide useful information on the mineralogy and textures shown by pyrite and arsenopyrite particles that have been roasted to enhance extraction of gold from refractory gold ores. Dark-field reflected-light microscopy has been found to especially reveal the extent of development of porosity and permeability in the ...

Implementation of Mineralogical Analysis in Cement Processing
2019Assessment of the mineralogical phase composition of cement and its intermediates play an increasingly important role in cement production. Traditionally, sampling for phase analysis has mostly focused on the kiln and cement. The most essential mineralogical analysis is the free lime quantification for optimizing kiln operation along with the ...

Process mineralogy of fluorosilicate minerals in ok tedi ores
Minerals Engineering, 2001The impact of fluorine in copper flotation was relatively unknown until the introduction of skarn ores in the Ok Tedi concentrator. Fluorine in the copper concentrates reports to the gas phase during the smelting stage and forms a corrosive H2SO4-HCl-HF acid brine mixture which must be neutralised.

Applied Earth Science, 2004
AbstractThe Nalunaq deposit is a shear-zone hosted gold deposit, characterised by high grades (up to 5240 g/t Au over 0˙8 m). The host rocks are Palaeoproterozoic metamorphosed mafic rocks in the Nanortalik district in South Greenland. As a generic type, the Nalunaq gold mineralisation is a mesothermal vein-type gold deposit, hosted in ...

Process Mineralogy of Lateritic Nickel Ore
2015This chapter presents a methodology for studying low-grade lateritic nickel ore, which usually presents complex mineralogy, with widespread nickel in several mineral phases. The study is focused on determining the mineralogy and the distribution of nickel in the bearing minerals.

Mineralogical characterization of chromium ore processing residue
2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011Understanding the mineralogical characterization of chromium ore processing residue (COPR) is the basis of soil remediation which is polluted by chromium. Some techniques, such as X-ray fluorescence (XRF), X-ray diffraction technology (XRD) and environmental scanning electron microscopy (ESEM), were applied to identify the elemental composition ...

Process mineralogy as a tool in modelling mineral processing operations.
2008One of the challenges in the development of mineral processing simulators is modelling the liberation characteristics of particles produced by comminution circuits. Understanding the mineral characteristics of these particles is one of the keys to predicting their behaviour in separation circuits.
