Meanwhile, concerns about a slowdown in China were also having an impact on stocks, as well as a profit warning from polymer products group Fenner, which makes conveyor belts for the mining industry."[Chinese] government figures indicated manufacturing growth was weakening, contradicting recent signs of improvement in the economy and providing an excuse for some selling in raw materials," said Chris Beauchamp, Market Analyst at IG.The FTSE 100 was down 0.2% at 6,861 by midday after hitting 6,871.29 on Thursday, its highest close since May 14th when it reached a new 14-year high of 6,878.49.Investors were also focusing on a batch of mixed economic data from across the globe, including an improvement in consumer confidence in the UK, weak industrial production figures and stronger-than-expected inflation in Japan, and an unexpected dip in retail sales in Germany.Miners weigh on markets, Fenner plummetsRising iron ore supplies from Australia and Brazil have prompted a 9% fall in prices this month, with the value of the commodity having now fallen every month since December.

Diversified miners Anglo American, BHP Billiton and Rio Tinto were among the worst performers on the FTSE 100, with concerns over China also dampening sentiment.In another hit to sentiment in the mining industry, Fenner issued a profit warning, causing shares to sink sharply.
