BHP Billiton's profit to exceed $10 billion

Global mining company BHP Billiton is expected to post an annual profit exceeding $10 billion due to the strong demand from Asia, particularly China and increase in copper prices. Estimates of the profit figure to be announced Wednesday range from $10.2 billion to $10.6 billion, eclipsing the previous year's $6.5 billion. The company announced record production levels for iron ore, aluminum, copper, nickel and natural gas last month, figures that are expected to translate into a higher annual profit.
