Clive Palmer's Queensland nickel refinery breaches ammonia levels

Queensland Nickel Sales took samples from two creeks and advised environment department that excessive ammonia levels were detected

Clive Palmer's north Queensland nickel refinery has contravened its environmental licence because of elevated ammonia levels in two creeks, tests show.

The Yabulu facility, which is being operated by a skeleton staff after 550 workers were sacked last week, is required to report excessive chemical levels to the environment department within 10 business days, in accordance with its environmental authority.
