May 24, 2012 The Kimberley Process Certification Scheme, established to end the trade in blood diamonds, last November cleared three diamond companies working in the region Mbada, Marange Resources, and Anjin to auction their diamonds internationally.After that action, Global Witness withdrew from the pact, citing the approval as a prime reason for its decision.
Jan 01, 2003 This indicates the enhancement of radiation in the environment due to tin mining activities. Tin ore is a radioactive mineral, which is rich in monazite and zircon components Babalola, 1984. During the tin ore processing operations, uranium and thorium concentrate and are responsible for the observed high concentration levels measured in the tailing dump and contaminated soil samples.
The range and means of measured dose rates and activity concentrations of 40 K, natural U and Th in environmental samples of a Nigerian tin mine and its tailing sites are presented. The measured concentration levels of eU and eTh in tailing samples and the measured dose rates were found to be elevated with values up to approximately 100 times above background levels of control soils.
