(Corrects spelling of 'lanthanide' in paragraph 1)
Dec 17 (Reuters) - Australian rare earths miner Lynas Corp Ltd LYC.AX said on Tuesday it was unsuccessful in securing approval from a Malaysian regulator to increase its lanthanide concentrate processing limit for 2019.
As a result of the regulator's decision, the miner's total neodymium and praseodymium (NdPr) production for calendar year 2019 will be similar to that of 2018, it said.
