The concept has been talked about for decades, but until now it’s been thought too difficult to operate in the high-pressure, pitch-black conditions as much as 5km deep.

Now the technology is advancing to the point where dozens of government and private ventures are weighing up the potential for mines on the ocean floor.

The rocks of the seabed are far richer in valuable metals than those on land and there’s a growing clamour to get at them.Billions of potato-sized rocks known as “nodules” litter the abyssal plains of the Pacific and other oceans and many are brimming with cobalt, suddenly highly sought after as the boom in the production of batteries gathers pace.

At the moment, most of the world’s cobalt is mined in the Democratic Republic of Congo where for years there’ve been allegations of child labour, environmental damage and widespread corruption.

Nickel, which is used to make stainless steel, is the best performing base metal on the London Metal Exchange this year. It has advanced by more than 8 per cent, outpacing zinc (up 2.1 per cent), copper (down 4.5 per cent) and aluminium (off 1.9 per cent), helped by the new export rules in Indonesia, the world’s biggest supplier of nickel ore.

Commodities trader Glencore Xstrata says demand for commodities up, but takes big charges

LONDON – Commodities trader and producer Glencore Xstrata says global demand for its raw materials is expected to grow, but that its earnings have been hit by big one-time charges.

The expenses, many associated with Glencore’s takeover of Xstrata, pushed the company to a net loss of $7.4 billion last year, compared with a profit of $1 billion the previous year. Not counting those expenses, profits rose 20 per cent to $3.67 billion.

Chief Executive Ivan Glasenberg says the company sees healthy demand growth in key commodities, “underpinned by the long term trend of urbanization in emerging markets and parts of the developed world returning to trend growth.”
