Geological resources: there is not only oil that will miss!

Current Economy and Sustainable Development-compatible? GDP growth (at all costs), economic development, inflation ... How concillier the current economy with the environment and sustainable development.

Read yesterday in a TV magazine: if we gathered the 160 tons of gold currently "owned" by man (the majority being in the form of jewels) and that we melt them into a single cube, this one would not exceed 000m side.

Surprising isn't it?

Already two years lost !!
Gold is heavy like uranium, lead, etc. residues of supernova which created us 5 billion years ago !!!!
The sun does nothing heavy.
Weird much cheaper silver will disappear before gold.

Speculate on money !!

An interesting source of information for metals is the USGS (US Geologic Survey).

For example for tin (2012) the sheet XNUMX on production and reserves: http://minerals.er.usgs.gov/minerals/pu ... 12-tin.pdf

2011 production = 253 tonnes, reserves 000 t

or a reserve / production ratio of 4 / 800 = 000 years only.

Thank you for this new source.

19 years in 2011 is the same order of magnitude as 37 years in 2006 (see 1st message) ... given the uncertainty that reigns over the quantities of geological mineral resources ...

of tin there are full our electronic device! if I unsolder everything with my desoldering iron all the tin ends up in the vacuum cleaner ... if I put the device in the recycling center the official recycling is a masscre which does not recover much

we must store all our old devices which will be a treasure when metals have more value ... and when we work better

it exasperates me to see spending public money on pseudo recycling which is often massacre

Christophe wrote:These figures need to be qualified since, unlike consumed oil which is "lost", metals can be recycled to a certain extent ... and be looped back as a resource.

Now recycling has its limits too. If someone has specific information above, it would interest me! For example: when I buy 1 kg of aluminum or steel, what is the% recycled.


no matter what is recycled: what matters is what will be recyclable when we need it

the heaps of waste from the middle ages forges could be used as iron ore in modern blast furnaces

our current discharge will be used as a mine one day ... it would be more intelligent to store our waste without crushing or burning them! metals would be easier to sort than mixed with garbage

Hmm ....
it does not mean much, I find or so it should not be taken in absolute values ​​of years but only as a comparison.

indeed:
-some of these materials are not "consumed" while others are such as coal or oil. not recyclable.

-secondly, for both geological and financial reasons, when we come to the end of the reserve of a resource (in fact, once half the exploitation is over) the resource is more difficult to extract, the more expensive and therefore less consumed.
therefore the number of years of reserves based on the current consumption means nothing.
