Reuters reported that 8 miners died earlier this week in an accident at a Hunan Nonferrous Metals Holding Group Company tungsten mine in China but production was not affected.

As per report, the miners died of gas poisoning at the Yaogangxian mine. Yaogangxian, one of the world's richest tungsten deposits is in Chenzhou in Hunan province.

Last August, the provincial government suspended all of Chenzhou's 270 coal mines for the rest of 2009 after an accident at a graphite mine killed 15 people.
