> was 72.95 points higher at 3,585.04, recovering after a 3.1 percent drop on Tuesday that saw blue chips plumbing six-year lows.Miners were the biggest gainers in the FTSE 100, as fresh manufacturing data from China offered a glimmer of hope that the downturn could be bottoming out. [
]"The miners were leading the market up. It's a Chinese story first and foremost. The last lingering hope for the miners in the midst of the global recession is that the Chinese economy manages to keep growing through 2009 and 2010," said Jim Wood-Smith, analyst at Williams de Broe.
"The hope is that Chinese infrastructure investments will be increased significantly during the course of the year," he said.
Kazakhmys <KAZ.L> was the top FTSE 100 gainer, up 12.1 percent, while Eurasian <ENRC.L>, Antofagasta <ANTO.L> and Rio Tinto <RIO.L>, gained between 6 percent and 9 percent.
Xstrata <XTA.L> added 10.8 percent as Goldman Sachs lifted its price target and kept a "buy" recommendation on the stock.
Insurers also gained ground with Prudential <PRU.L> and Aviva <AV.L> up between 7.0 percent and 9.0 percent.
"When the market falls, the equities of the life businesses fall more, and when the market rises, they rise even more," Wood-Smith said.
Old Mutual <OML.L> was up 0.8 percent as the South African-based insurer allayed funding worries with broadly in-line full-year results.
Old Mutual's chief executive said he believes the company will have sufficient capital for 2009 as it scrapped its current-year dividend to preserve cash.
Banks recovered after falling deeply into the red zone during previous sessions.
Within the sector, Standard Chartered <STAN.L> gained 8.2 percent, following Tuesday's solid full-year results, while Barclays <BARC.L>, HSBC <HSBA.L>, and Lloyds Banking Group <LLOY.L> added between 4.2 percent and 9.0 percent.
Heavyweight oil and gas producers added the most weight to the blue chip index, rallying as the crude price <CLc1> pushed back above $42 a barrel on the positive news from China.
BP <BP.L>, Royal Dutch Shell <RDSa.L>, BG Group <BG.L>, Tullow Oil <TLW.L> and Cairn Energy <CNE.L> rose between 1.9 percent and 3.0 percent.

]British consumer confidence improved in February for the first time in four months and the rate of job cuts slowed a fraction, a purchasing managers' survey showed on Wednesday.
Investors focused ahead to the two-day meeting of the Bank of England Monetary Policy Committee meeting on monetary policy starting on Wednesday, which will conclude with a rate decision on Thursday.
AstraZeneca <AZN.L> was the top blue chip faller, down 2.4 percent as defensive issues fell back on the market recovery.
New research also suggesting that blood thinner Plavix interacts badly with common heartburn drugs is a potential threat to AstraZeneca's <AZN.L> top-seller Nexium rather than Sanofi-Aventis' <SASY.PA> Plavix, analysts said. [
]Other drug stocks were weak with GlaxoSmithKline <GSK.L> down 0.7 percent, Shire <SHP.L> off 0.1 percent, and medical products company Smith & Nephew <SN.L> losing 2.3 percent.
