Chinese high-carbon ferro-chrome prices have increased by 500-550 yuan ($73-80) per tonne since mid-December on higher ore costs, market participants said.

    High-carbon ferro-chrome is selling at 7,800-7,900 yuan per tonne in China’s spot market, up from 7,250-7,300 yuan per tonne two weeks ago.

    “Many ferro-chrome producers further lifted their offers by 50-150 yuan per tonne this week to reflect their increased chrome ore costs,” said a trader in Shanghai.
