Mineral Processing/Ore Dressing
After mining the first step in the metallurgical process is mineral processing. This step prepares the ore for extraction of the valuable mineral. It is a process of physically separating the grains of valuable minerals from the waste minerals. This enrichment process considerably reduces the volume of mineral that must be handled by the extractive metallurgist. (See Mineral Processing Technology by B. A. Wills, First Edition 1979, Pergamon Press, Maxwell House, New York, 10523)

Rewrite
I totally re-wrote this page. Nobody was really doing any maintenance on this article. It was a hodge-podge of different concepts, repeated itself in many places, and got into way too much detail that is covered in other specific sub-category articles. I don't think that I eliminated anything that isn't covered elswhere. If I did, and it truly belongs here, let's get it back in. Comments and input in making this a better article will be very much appreciated.BSMet94 (talk) 20:13, 23 July 2010 (UTC)

I also tried to make the article more generic, and not get into specifics of any process for any particular material. Details of generic processes (floation, solvent extraction, roasting, smelting, electrowinning, etc.) belong in other main articles and detials of specific processes for copper, iron, gold, zinc, etc. belong in the articles discussing those metals and their extraction processes. Also, I had a line in there about ferrous vs. non-ferrous metallurgy. I took that out. It doesn't need to be discussed, it's non-technical, and it was bound to start an argument.BSMet94 (talk) 20:23, 23 July 2010 (UTC)
 * This is a decent high level article, leading to a more detailed one. However, it ought to have a reference or two.  I doubt that it needs in-line citations, but there ought to be a short bibliogrpahy.  Peterkingiron (talk) 18:37, 27 July 2010 (UTC)
 * Thanks for keeping me honest. I added one reference that I used very generically when writing the article.  Most of it, I just wrote from my general knowledge.  There are no quotations, and I don't think anything I wrote is controversial, so at this time, I agree that in-line citations are not needed.  I hope this article gets some scrutiny, and if any controversies come up, then we can resolve them with revisions and in-line citations as necessary.  It's been a few years since we collaborated Peterkingiron, but It's always fun when we do!BSMet94 (talk) 15:37, 28 July 2010 (UTC)

Ellingham Diagrams
This topic is incomplete here. The horizontal axis is clearly the chemical oxidation/reduction environment, but the vertical axis seems not to be defined here at all. Is it ph, temperature, time, pressure or what? I shouldn't have to read another article to find this out. David R. Ingham (talk) 04:26, 12 November 2011 (UTC)
