Wednesday ushered in a mixed performance from European stock markets, with London's FTSE 100 index closing higher for the day, while benchmark indices in Germany, France and Spain closed lower.

The FTSE 100 rose by 0.12% to close at 6,673.31. Mining stocks were the biggest gainers in London, on stronger metals prices.

Copper, aluminum, iron ore, lead and zinc all gained during the European session, with Glencore (GLCNF) and Anglo American (NGLOY) vying for top spot on the FTSE 100 leader board, after rising 2.49% and 2.53% respectively.

Anglo American drew additional strength from reports that China Molybdenum (CMCLF) has signed a $900 million syndicated loan agreement to acquire the niobium and phosphate assets it is buying from it.

In Germany, the Dax was down 0.08%, closing at 10,378.40. Utility and industrial firms RWE (RWEOY)  was the biggest contributors to gains, after rising by more than 1%.

RWE pared some of Tuesday's losses, which were caused by reports among German media outlets that it and other utilities will have to stump up even more cash to cover the cost of Germany's managed withdrawal from nuclear power.

Bayer (BAYRY) rose 0.27% after the life sciences company announced that it has clinched a deal to buy U.S. agricultural seed maker Monsanto, bringing an end to an escalating series of bids for the asset.

In France, the Cac 40 was lower at the close, by 0.39%, coming to a standstill at 4,370.26.

Luxury goods maker LVMH (LVMUY) was the biggest detractor from returns on the index after it fell more than 2%.

Weakness in LVMH stock came in tandem with a sell off across the wider luxury goods sector, which was hammered when compatriot Hermes (HESAY) sank the mood among investors with bleak guidance for its full year financial performance.

In Spain the IBEX 35 closed lower for the day, down by 0.25%, at 8,702.40. The biggest faller on the index was Banco Populare (BPESF) , which lost 1.2%, amidst a broader sell off in the banking sector.
