Value adding in Australia - the beginning of the end?

Mines can only be where the deposits are found. But smelters and refineries can be located anywhere between the mine and the ultimate customer for the metals. And just three factors dictate where metal processing is located – political costs, processing costs and transport costs. The political cost (tax burden) depends on the common sense of the electorate and their knowledge of where the real wealth is created. The processing and transport costs depend mainly on the local costs of wages and energy.

The first trains and power stations all used steam engines burning low cost local coal. Then came cheap diesel transport for trucks and trains. Now electric trains are again running on cheap Australian coal. This low cost carbon energy supported our high wages and ensured that mineral processing became a big business in Australia – iron and steel, lead-zinc-silver, copper, nickel, aluminium, gold, uranium, limestone, coal, oil and gas are all processed to some extent in Australia.

There is no point introducing a carbon tax that does not increase the cost and thus reduce the use of coal and diesel energy. Mining and mineral processing and transport probably consume over 50% of Australia's electricity, which is mainly coal powered with minor gas. And they are huge users of diesel for utes, trucks, shovels, dozers, scrapers, mobile power and drilling rigs. Therefore, no matter what they say, all of Australia's mineral processing advantages are threatened by their carbon tax.

The recent Xstrata decision to phase out their world class copper smelting and refining operations in Australia tells us that the taxes, processing, transport and energy costs that Xstrata expects in Australia are already uncompetitive.

The dreamers in the Canberra cocoon always drool about "value adding". Their carbon tax will surely cause all mineral processing plants in Australia to lose value, and some will surely close. Low cost coal and diesel power will no longer support our high wages. The value adding will take place in Asia.

We are watching a slow tragedy unfold - the end of an era. Once the mineral processing plants leave, they will never come back. We will be back to the pioneering era of mining – dig it out and ship it off.

And the final tragic irony of the Isa story is this – sending partly processed copper concentrate overseas, instead of smelting it at Mount Isa, will about triple the transport burden and do the same to carbon dioxide emissions.
