Mine Protests Spread in South Africa

It's been just a week since 34 were shot at one demonstration

Workers clamored for higher wages Wednesday at two more platinum companies in South Africa's mining heartland, less than a week after police shot and killed 34 people at a violent protest at Lonmin PLC's Marikana mine.

Miners at the world's biggest platinum producer, Anglo-American Platinum Ltd., or Amplats, and Royal Bafokeng Platinum Ltd. echoed the Lonmin workers in calling for better pay and working conditions.

Amplats said a group of workers submitted demands including a wage increase at its Thembelenmi mine. The company said there was no strike yet.
