Introduction to MinAssist capabilities in mineral processing and project development

When I started MinAssist over 15 years ago it was to focus on making process mineralogy more accessible in mineral processing. We […]

Considerations with QEMSCAN Grain Size Estimation

Most SEM-EDS systems have the ability to compute grain size. Not all systems use the same computational methods and we advise that […]

Have you measured enough particles?

One of the key questions about SEM-EDS data is whether or not you’ve measured enough particle sections to produce a representative result. […]

The Applied Mineralogy User Community

The field of applied mineralogy has always had a basis in a strong community, this has led to to numerous developments that […]

THE IMPORTANCE OF MINERAL DEFINITIONS USED IN GENERATING QEMSCAN DATA

The most common approach to assessing the accuracy of QEMSCAN mineralogy results is to compare the measured assay with the mineralogy-computed chemical […]

Three areas that may affect the quality of your mineralogy data

  The complex nature of QEMSCAN mineralogy results necessitates a thorough assessment of data quality relative to ‘best practices’ values. The MinAssist […]

HAVE YOU VALIDATED YOUR MINERALOGY DATA?

Do you rely on routine SEM-EDS mineral analysis to monitor or drive process development and operational optimisation? Have you ever considered the […]

Upskilling the Workforce using Operational Mineralogy

Increasingly mining companies are recognizing the need to take on new technology developments in order to increase the efficiency and productivity of […]

How do geometallurgical models relate to operational mineralogy?

In preparation for the AusIMM Geomet ’16 conference in Perth next week we thought a brief introduction to how operational mineralogy can […]

How can Operational Mineralogy be used to increase the efficiency of the identify, diagnose, execute, augment (I.D.E.A) cycle for continuous improvement?

The approach in Operational Mineralogy is to focus on generating mineralogical data that is useful for particular goals.  This helps to identify […]

Workshop: Basics of Operational Mineralogy

    For all of you who are going to, or thinking about going to, the AusIMM Geomet 16 conference in Perth […]

iMin (mineral) – building operational mineralogy capability for minerals processing

The iMin(mineral) package was developed by Dr Will Goodall at MinAssist as a tool for minerals processing operations to effectively access routine […]

The use of trend based mineralogy in continuous process improvement

The analysis of daily composite samples forms the core component of any operational mineralogy program.  This provides a snapshot of the daily […]

The iMin Workbench – A framework for predictive control with mineralogy

Since the introduction of automated mineralogy almost 40 years ago the holy grail has been to bring the capability to operational sites. […]

What are the key goals of an operational mineralogy program?

Many operations deal with orebodies that are highly variable in metal grade, ore mineralogy, gangue mineralogy and processing behaviour. Ore with complex […]

Introducing iMin Solutions – a new way to build mineralogy capability in operations

We are pleased to announce that MinAssist, along with Petrolab have teamed up to establish iMin Solutions, a company focused on bringing […]

Successful operations are focussing on mineralogy to improve productivity

A recent article in the Mining News commented that ‘miners have gone from the growth at all costs phase to maximising the […]

7 Considerations in setting up an operational mineralogy program

The use of routine mineralogical characterisation of targeted process streams can have significant value for an operation.  This is especially true where […]

Why we should consider operational mineralogy

  In most operations we understand that minerals are being processed but we tend to almost exclusively rely on chemical assays to […]

Petrolab adds new automated mineralogy capability

  Petrolab, our great friends in Cornwall, UK have been busy over the last few months building up their capability in automated […]

Why use screened fractions in automated mineralogy?

The use of screened fractions at the simplest level is done to provide cleaner data by helping to reduce touching particles and the bias that can be introduced through stereological effects. There are well documented reasons based on the mathematics of converting 2d section images into 3d particles (stereology), which show that if we want to generate a meaningful grain size distribution it should be required that screened fractions are analysed. Stereological corrections work well because they calculate 3d parameters based on a statistically random distribution of particle orientations.

Flotation mineralogy: Valid and Valuable?

Following on to the conclusion of another successful MEI conference, Flotation ’13, some interesting comments and feedback have emerged that highlight the […]

Operational Health Check Suite

Over the last few months, MinAssist has progressively launched a series of “Operational Health Checks” that have been developed as suite of off-the-shelf […]

Process Mineralogy in optimization and troubleshooting

I wanted to start our exploration of process mineralogy in the middle of the mine life cycle, with its use in process optimisation and troubleshooting. Why start here you ask? Well process mineralogy can have the biggest impact and finds the most use in this area so it is a great introduction.

The how, what and where of process mineralogy

Welcome to the new addition of the MinAssist blog, to be known as ‘Process Mineralogy Today’. This blog has been developed by MinAssist to promote the use of process mineralogy within operations and as a forum to promote discussion on the most effective ways to achieve this. I encourage you as the readers to comment on the ideas presented and add your comments on where you see process mineralogy going in today’s industry.
