Im pretty sure Mutoroo process was actually power positive,
it would generate power to return to the grid or whatever
"Metallurgical studies indicate that a modern roasting / acid plant would be capable of efficiently recovering all valuable products including sulphuric acid, copper, cobalt, iron ore and electricity. "

Facts are awesome hey!
Mutoroo was at one stage I am pretty sure stated as around $400 a tonne ore
actually here a part of an email that I sent Chris in July 2011 when I was discussing about the glencore saga
Mutoroo ??, 13.1m tonnes of ore at ?300-?450 per tonne, that's lot's. 3 years ago Helionjang stepped aside, where have we gone?
At $300/t thats 4 billion dollars worth
from 2010
"Quite extensive metallurgical test work has been completed on the Mutooroo sulphide ore showing that it can produce a high grade copper concentrate by conventional flotation. However, maximum value can be extracted from the ore by roasting it, thereby liberating both copper and cobalt and utilizing the high sulphur content to produce sulphuric acid. The residue remaining is very pure iron ore."
Two potential development options are presently being investigated by Havilah in order to maximize the value of the Mutooroo deposit:
1. Construct a roaster in South Australia and market the acid locally, to take advantage of the high local demand. Havilah's studies indicate that the cost to build a roaster with a throughput of approximately 500,000 tpa is more than A$300m.
2. Ship the sulphide concentrate to an offshore smelter / roaster. Havilah has employed a consultant to investigate this possibility in China over the last few months, with some positive results. This alternative would result in a lower net return to Havilah, but cash-flow could be achieved earlier and the initial capital cost to build a roaster could be avoided altogether.
