Having scanned this thread, I cannot help but add that 'Blister Copper'
(also blister-ore etc)is applied to a particular form of Chalcopyrite
(having a blistered, nodular and occasionally stalactitic appearance), and
is remarkably pure - forming
pure nodules weighing up to several kilos (or more?).
I have heard the same term used for copper straight out of the smelting
furnace, and still highly impure (it contains bubbles of all sorts - mainly
trapped slag, but also gasses)
Like most terms used in industry (as opposed to the academic 'strictness'
:) the terms are going to be used for a range of
products/materials/processes etc.
I suppose that finding someone daft enough to compile a definitive
dictionary of mining terms is out of the question? <wry grin>
Regards,
Paul
