News Release: Updated MinAssist website and Process Mineralogy Digital Book

ipad-digital-book 1MinAssist has today released our new website ( along with a free digital book “Integrating Mineralogy into Everyday Solutions”.


The MinAssist website has been developed to provide a simple user interface focused around promoting the value that Process Mineralogy can bring to the minerals industry.  Over the next few months we will be adding lots of exciting content on MinAssist services and a variety of resources to simplify the use of Process Mineralogy.


To complement the launch of the website we are really excited to include a free digital book for download.  The book, “Integrating Process Mineralogy into Everyday Solutions”  was written as a tool to give an overview of what Process Mineralogy is being used for, how to set up effective programs and what techniques are available.  We hope that this becomes a useful resource for anyone interested in understanding more about Process Mineralogy and setting up their own programs.


We encourage you to download the digital book and have a browse around the website.  If you would like to keep in touch with the upcoming additions then feel free to sign up to the MinAssist Newsletter so that we can keep you informed.


Any feedback on the new website and the digital book would be more than welcome.

Reducing the cost of grinding

2_Oyu Tolgoi_SAG Mill_#1The grinding circuit in any operation is a major contributor to overall operating costs and should be a major focus of ongoing process optimisation and improvement programs.  The grinding circuit can account for up to 40% of energy costs within a process circuit.  Understanding the behaviour of material through the grinding circuit is a significant step on the right path for reducing costs, minimising energy use for sustainable practice and ultimately improving recoveries in down stream circuits.  To help with this MinAssist has developed the first in a suite of off-the-shelf services to make undertaking a Grind Optimisation Program accessible and easy.



MinAssist welcomes Al Cropp to the team

Al CroppMinAssist would like to welcome Al Cropp to the team. Al has nearly 10 years working within process mineralogy, primarily through developing applications for the automated mineralogy techniques of QEMSCAN and MLA. Al is a geologist and graduate of the Camborne School of Mines, and a gemologist with a Fellowship of the Gemmological Association of Great Britain.


Al specializes in working with clients to enable them to maximize their use of, and benefits from, mineralogy within the mining, mineral processing and tailings management process. Al has experience with copper and base metals, gold, coal mineralogy and environmental particulates such as dust.


Al will form a core part of the MinAssist team, expanding our expertise further in the process mineralogy and geometallurgical space. He has prepared numerous publications (link) and presented at conferences across the world on all aspects of process mineralogy, from mineral processing, to coal analysis and environmental mineralogy. Feel free to check out his publications and presentations at the MinAssist website.


Al will be available to answer any of your questions and as always with MinAssist don’ hesitate to drop him a line with any query you may have about process mineralogy.
