I revised the article quite a bit. Mainly, I re-organized it into what I think is a more logical progression. It's still missing a lot of information, and I didn't cover everything. But it's a start! Would be nice if someone else could add to it.BSMet94 23:18, 26 January 2007(UTC)

I added a link to the world leader in hydrometallurgy that patented some environmentally friendly processes. I think the article should talk to some degree about environmental impact and the likely future interests governments will have in reusing mining waste.

This isn't spam this is a link I used to find out about hydrometallurgy in Australia, whose export industries are dominated by mining and has the largest Mining company in the world, BHP, based there. I put it back, it's an important link to an example, the best I could find, of a Hydrometallurgy company. Anon 14:14. 4 January 2007

history note

Henry Livingstone Sulman

Born 15 Jan 1861; died 31 Jan 1940 at age 79. British metallurgist, one of the originators of the froth flotation process for concentrating ores preliminary to the extraction of metal (with H.F.K. Picard, U.S. patent No. 835120, 6 Nov 1906). In this latter method, crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. These reagents, such as oil or fatty acids, are chosen for a preferential affinity for metalliferous matter over the waste material (gangue). When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface, whereas gangue settles to the bottom. The froth is skimmed off, and processed. Sulman had previously worked on several methods for the extraction of gold, including treatment with cyanogen bromide.
