It is reported that workers demanding better pay at Brazil's Companhia Siderurgica Nacional's Casa de Pedra iron ore mine went on an open ended strike over the weekend.

While CSN said the mine is operating normally and output of iron ore was unaffected but the union said participation in the stoppage was affecting output.

The Minas Gerais state mine accounted for a third of CSN's revenue last quarter, and workers are demanding a greater share of profits.

The union said the mine employs 2,300 workers and produces 60,000 tonnes of iron ore a day.
