Hazelwood X-ray feed sorting trials a success

  Hazelwood says it has successfully used X-ray sorting on a wider range of feed sizes on low grade feed from the Big Hill Tungsten Deposit.
According to Hazelwood, the successful trial of X-ray sorting means the low grade material can be upgraded into mill feed. As a result, a wider range of materials from Big Hill could be bulk mined and processed.
Hazelwood says the latest X-ray sorting tests were conducted on representative samples of crushed, low grade drill core. The results confirmed that feed sizes up to 60mm can undergo significant upgrading.
X-ray and optical sorting are pre-concentration techniques which have been successfully applied at operating tungsten mines.
X-ray sorting reduces the required size of the milling and beneficiation circuit, reduces grinding costs, lowers the demand for water, and results in smaller wet tailings storage facilities.
