London - Platinum producer Lonmin [JSE:LON] has completed repairs and restarted operations at one of its furnaces and has ramped up production at its second furnace within schedule, the world's third-largest producer of the precious metal said.
The miner was hit by technical problems at both its furnaces late last year which has reduced its refined platinum output and sales in the last few months.
Furnace number one was stopped in early December for three months to fix a leak of molten furnace matte while furnace number two was halted at the end of December to address electrode breaks.
