SHANGHAI, Sep 11 (SMM) – State-owned mining company China Northern Rare Earth Group raised the listed prices of light rare earth products for September, including praseodymium-neodymium oxide and praseodymium-neodymium metal, by around 4% from that in August, according to a notice on the company's website on Tuesday September 10.

Expectations of tighter supplies on the closure of some smelting and separation plants could account for the higher quotes for September. 

The adjustment buoyed the listed price of praseodymium-neodymium oxide to 355,000 yuan/mt, up 4.4% on the month, and that of praseodymium-neodymium metal to 435,000 yuan/mt, up 3.6% from August. 

Listed prices of neodymium oxide also jumped 4.4% to stand at 357,000 yuan/mt, and prices of neodymium metal rose 3.6%, and posted 435,000 yuan/mt.

Listed prices of lanthanum oxide and cerium oxide remained unchanged at 13,000 yuan/mt. 

Separately, another state-owned rare earth mining company, China Southern Rare Earth Group, marginally adjusted its weekly listed prices for medium and heavy rare earth oxides, according to a statement on September 9. 

Prices of gadolinium oxide were lifted by 7,000 yuan/mt on the week to 182,000 yuan/mt, with a decline of 10,000 yuan/mt in prices of europium oxide, standing at 270,000 yuan/mt. Listed prices for other medium and heavy rare earth oxides were left unchanged.
