Mineralogical characterization of chromium ore processing residue

2011 International Conference on Electric Technology and Civil Engineering (ICETCE), 2011
Understanding 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 of roasted pyrite and arsenopyrite

JOM, 1992
Process 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

2019
Assessment 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 ...

Application of process mineralogy as a tool in sustainable processing

Minerals Engineering, 2011
The observed behaviours of mineral particles in mineral processing operations have been exploited in the past to model comminution and concentration processes. In this work this concept has been taken a step further, exploiting the mineralogical characteristics of particles to link comminution, concentration and smelting.

Mineralogical characterisation and process mineralogy of goldbearing rocks from the Nalunaq gold deposit, Greenland

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 ...

Study on Processing Mineralogy of Xuanhua Iron Ore

Applied Mechanics and Materials, 2011
The chemical component, mineral composition and dissemination characteristics of Xuanhua iron ore are researched systematically. The result shows that: the iron ore mainly is oolitic structure and colloform, xenomorphic granular texture, the mineral composition is complex, the primary metallic minerals is hematite, and the rocky minerals mainly is ...

Application of automated quantitative mineralogy in mineral processing

Minerals Engineering, 1991
Abstract There has been considerable interest in recent years in the development of automatic systems for the measurement of mineral composition and texture to help solve mineral processing problems. These rely on three major operations — the automatic identification of the minerals, the creation of an image representing the mineral sample and ...

Process Mineralogy Study on a Sandstone Copper Ore

Advanced Materials Research, 2014
In this thesis the object of study is a low grade sandstone copper with complex composition. Through the process mineralogy research on a sandstone copper ore,the result showed that the primary sulfide copper minerals are tetrahedrite and chalcopyrite; secondary sulfide copper minerals are bornite, chalcocite and azurite; the main oxide copper mineral ...

Research on Process Mineralogy of some Pyrite Cinder

Advanced Materials Research, 2013
The characteristics of process mineralogy of some pyrite cinders were studied with optics microscopes, scanning electron microscope, and x-ray diffraction. The chemical composition and the phase composition of the pyrite cinders were analyzed. The occurrence and chemical phase analysis of molybdenum of iron, copper, and gold were also studied.
