The process mineralogy of mine wastes

Minerals Engineering, 2013
The discipline of process mineralogy developed through the recognition that metallurgical flowsheets could be optimised by thorough characterisation of the precursor ore mineralogy, mineral associations, grain size and textures. In a procedure analogous to process mineralogy it is shown here that effective characterisation of mine wastes for Acid Rock ...

Sampling – A key tool in modern process mineralogy

Minerals Engineering, 2018
The powerful modern toolbox of hybrid Process Mineralogy for flowsheet development uses best practice sampling as one of its tools. In this paper, the three key components of best practice sampling are reviewed with case studies. These three components are:

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.

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 ...

Developing and sustaining capability in process mineralogy

, 2016
There are a number of disciplines in the minerals industry for which concern has been expressed regarding the sustainability of human capital. The boom-bust cycles that occur in the industry, the trend in tertiary education towards consolidation or in some cases cessation of minerals related programs and the increasing frequency of fly-in fly-out ...

The Status of Process Mineralogy in 1988

JOM, 1988
Although the field of applied or process mineralogy has been recognized for some time, its importance has been most significantly realized only in the past ten years.
