South African police fired teargas and rubber bullets to disperse striking miners at a gold mine near Johannesburg on Monday, the latest outbreak in a wave of labour militancy spreading from platinum mining into other parts of the sector.
The unrest occurred less than three weeks after police shot dead 34 striking miners at Lonmin's Marikana mine, the bloodiest security incident since the end of white-minority rule in 1994.
The Marikana shooting shocked South Africa and marred the image of the continent's biggest economy, as the full extent of a breakdown in labour relations in the mines became apparent.
South Africa is home to 80 percent of known platinum reserves and the price of the precious metal, used in jewellery and car catalytic converters, has risen more than 10 percent since the violence erupted.
