Joseph Mathunjwa (C, in green), president of the Association of Mineworkers and Construction Union (AMCU), joins mine workers in a song after addressing them outside the Lonmin mine in Rustenburg, northwest of Johannesburg January 23, 2014. South African mines producing half the world's platinum shut down on Thursday as the sector's main union began a strike for hefty wage hikes their employers say they cannot pay. Members of the Association of Mineworkers and Construction Union (AMCU), walked out at Anglo American Platinum, Impala Platinum and Lonmin, the top three producers of the metal used in catalytic converters in cars.
