Irrelevant note but as nice as this graph is (and it's clear plenty of thought went into it) why does it include materials they didn't have information on? For instance, Hafnium.
- jodrellblank 18y agoAgreed, and moreso why don't they have information on Hafnium? Is it a secret? Does nobody have an estimate of how much there is scattered about? Are mining companies busy digging for diamonds or copper and oops a lump of hafnium pops up ('ooh what luck, I know a power station owner who will want that!')? I do hope there's some big Hafnium mining monopoly conspiracy behind this! ;)
- cschneid 18y agoI'm the type of guy who goes and googles this kind of thing..... It looks like halfnium is a byproduct of zirconium production (1:50 ratio is what the pdf says), and that we have a decent chunk of reserve (worldwide), compared with the rate it's mined. It's a riveting read: http://minerals.usgs.gov/minerals/pubs/commodity/zirconium/mcs-2009-zirco.pdf http://minerals.usgs.gov/minerals/pubs/commodity/zirconium/m...
