I made a few mods... not ALL stamp sand contains dangerous traces so I softened that by adding a "may"... stamp mill processing didn't always use heat. Copper ore especially, often had base metal that could be mechanically separated, or the metal could be removed by leaching. (these last two require a lot of process water which is why so many stamp mills are near water sources) Also I noted that there have been instances of previously discarded sand being gathered up and processed again (there is a big abandoned dredge on the Portage Canal in the Keweenaw Peninsula that was used for this, it's a striking photo). This is all sourcable, I'll have to try to dig for the sources. ++Lar: t/c 15:05, 24 December 2006 (UTC)

I deleted Iron from the stamping process. Iron ore was not stamped, in the older mines until Circa 1940's/1950's the ore was 'lump ore', it was shipped from mine to furnace with no processing involved. Any Crushing would have been done through a jaw/gyratory crusher. Stamps were used as part of the concentrating process, which wasn't needed until high grade deposits were worked out. CCI started concentrating Iron ore in Michigan at the Ohio Iron mine in Three Lakes, this mine was a modern style plant with ball/rod mills for grinding, and eventually this work carried over to the work at Eagle Mills, which created the modern pelletizing process. The use of stamps were skipped (no pun intended) to my knowledge. If anyone can point otherwise please do so! Djoeyd114 00:05, 30 May 2007 (UTC)
