A process mineralogy approach to optimize molybdenite flotation in copper – molybdenum processing plants

open access: yesMinerals Engineering, 2020
The Sungun copper-molybdenum operation in Iran uses a typical copper-molybdenum flowsheet to produce separate copper and molybdenum concentrates through flotation and regrinding of the rougher concentrates arising from the primary circuit.

Study on Mechanisms for Improving Quality and Whiteness of Phosphogypsum Based on Process Mineralogy Analysis

open access: yesMinerals (Basel, Switzerland)
Because of its low whiteness, complex composition, radioactivity and high impurity percentage, the usage of phosphogypsum (PG) resources is limited. A theoretical foundation for upgrading and bleaching PG can be obtained by researching the presence and ...

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 ...

Process mineralogy of fluorosilicate minerals in ok tedi ores

Minerals Engineering, 2001
The 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.

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 ...

Process Mineralogy of Lateritic Nickel Ore

2015
This 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), 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 ...
