Am working on implementing a Geometallurgy program in a mining operation. We know that it will not be an easy task but it is a risk we need to address.Understanding your mineralization and the distribution of metal carriers throughout your deposit i...

There are a couple of flavours of geometallurgy floating around the industry.  The first type I would classify as "process mineralogy" where you associate plant performance to the minerals in the pla...

I am trying to compile a brief history/genesis of geometallurgy from conception to present day. Does anyone know who first coined the term "Geometallurgy"? Which commodities, other than thermal coal, were employing "geometallurgical" concepts prior t...

This article has an interesting perspective on mineral resources and reserves. Thought that someone may be interested in this. Under what circumstances does a mineral become a mineral reserve? When does a mineral resource become a mineral reserve?htt...

I think the author of the article pretty much hit most of the significant situations and conditions that cause resources to be misunderstood. The author has spent most of his career apparently dealing...

Who can help me with some articles in geostatistics lecture notes on geometallurgy and grade control. Thanks

That mineralogy plays a part in geometallurgy is well-known. And if we look at some historical work we can see this was conjectured as early as 1939 (Gaudin). Perhaps there are earlier references.Simi...

Thanks for your comments. For iron ore it certainly makes sense to follow your suggested approach. I am working on a base metal mine tailings dam (Cu, Au, magnetite).

I'm in the middle if reading 'the signal and the noise' by Nate Silver. It highlights the traps of numerical analysis and the need for appropriate human judgement in predicting and forecasting. In the context of more geomet data and data processing, ...

I will try to track them down; I also look forward to looking up the TED stuff  - it will be interesting to see what other science fields are doing in the data analysis area.

I would be interested in hearing comments from people as to their level of interest and involvement in texture modelling. My particular interest is that I was Texture classification module leader for the AMIRA Geometallurgy project, and have receive...

Thanks. I had a quick read.  The key concept is that there are geometric probability equations that allow transformation of low dimensional data to higher dimensional data, and I briefly previously ...

When do you think the geometallurgical model starts to be used in an operation, and when does it add the most value?I see the potential challenge I see is that slight lag time between when big decisions are being made in the early stages of mine pla...

Investors and Policy makers place a lot of faith in the assumption that (hopefully) all of the company's reported reserves and (most of the) resources will be mined. The key question is, empirically what are typical conversion rates achieved by indus...

Total metal idea was a broad coverage of the theoretical metallisation potential. There is no cover for intransient testing or insufficient testing there in.
