The Group’s acquisition of Serov had a positive impact on the total volume of ore extracted by the Ferroalloys Division. Serov’s ore extraction was 33 00 tonnes and saleable ore production was 2000 tonnes. Saleable ore production increased 15.9%, of which 13.6% points were attributable to the existing business and 2.3% points were attributable to Serov. The inclusion of Serov resulted in an increase in the internal consumption of chrome ore by 9400 tonnes, or 14.9% points, whilst the proportion of ore consumed internally from total saleable ore production decreased to 71.9% in Q3 2008.
