Richards Bay Minerals, a joint-venture between Rio Tinto and BHP Billiton, has resumed full production after workers ended a week-long pay strike.

Richards Bay Minerals spokesperson Nthabiseng Motsep said the 586 workers, represented by the National Union of Mineworkers (NUM,) have all returned to work following the signing of a pay rise agreement by the company and the union.

The company said it has agreed an 8% pay rise with the NUM for 2010 and a guaranteed 7% increase each for 2011 and 2012, reports Reuters.

The strike has not affected production because a contingency plan was put in place to mitigate the effects of the strike.

Richards Bay Minerals, a joint venture between Rio Tinto, BHP Billiton and black economic empowerment partners Blue Horison, is a leading producer of titanium minerals, high-purity iron and zircon.
