* Oils and miners lead losers; banks recover
* Citigroup results in focus after mixed signals on banks

LONDON, July 18 (Reuters) - European shares slipped on Friday, weighed down by commodity stocks, while banks recovered ahead of key results from Citigroup <C.N>. By 0839 GMT, the FTSEurofirst 300 <
> fell 0.4 percent to 1,141.38 points, but was on track to eke out a gain of 1.4 percent for the week thanks to a jump on Thursday.Lower metal prices and a cooling off in crude took heavyweight mining and oil stocks lower.
Eurasian <ENRC.L>, Xstrata <XTA.L>, Rio Tinto <RIO.L>, Anglo American <AAL.L> and BHP Billiton <BLT.L> lost 3-6 percent as copper futures <MCU3=LX> fell 0.7 percent and gold <XAU=> traded lower.
Oil inched up to nearly $131 a barrel but was still off nearly 10 percent this week, and energy shares Total <TOTF.PA>, Royal Dutch Shell <RDSa.L> and BP <BP.L> were down 0.2-0.5 percent.
But investor focus shifted squarely onto results from Citigroup later in the session, after JPMorgan's <JPM.N> figures pleased investors but Merrill Lynch <MER.N> posted a bigger-than-expected loss on Thursday, sending mixed signals about a banking sector battered by a credit crisis.
Analysts said that despite Merrill, results from banks had not been as bad as feared.
"It's difficult to derive a general picture on the bank results, but one could say they are more reassuring than not," said Thierry Lacraz, strategist at Swiss bank Pictet.
"The results from Citigroup will be key because it is probably the most exposed to risky assets among the large banks."
Across Europe, Britain's FTSE <
> fell 0.3 percent, Germany's DAX < > gained 0.1 percent and France's CAC < > fell 0.4 percent. Depressing the tone was a Wall Street Journal report that embattled Freddie Mac <FRE.N> may sell as much as $10 billion in new shares to investors. [ ]
BANKS CHOPPY
Banks regained ground, with traders citing short-covering and hopes for reasonable results from Citigroup.
Commerzbank <CBKG.DE> rose 1.7 percent, Royal Bank of Scotland <RBS.L> gained 2.3 percent and HSBC <HSBA.L> added 1 percent.
"There has been some serious short-covering over the past day or two and that is continuing," said a trader. "People have made lots of money on the downside and want to lock in profits."
Banks led European shares out of a bull market that lasted four years to mid-2007, taken down by the credit crisis that had its origins in a meltdown in U.S. subprime, or risky, mortgages.
The FTSEurofirst 300 has lost 24 percent this year and is trading 30 percent below 6-1/2 year highs hit in July 2007, placing the index firmly in bear market territory.
"We continue to be underweight on the banking sector, but it will be a positive for financials, consumer stocks and the broad market if the oil price goes to $120," said Pictet's Lacraz.
Other major movers included Dutch retailer Ahold <AHLN.AS>, which fell 6.5 percent after Belgian rival Delhaize <DELB.BR> spooked investors in the sector by cutting its profit outlook. Delhaize slumped 16 percent, France's Carrefour <CARR.PA> lost 2.6 percent and Tesco <TSCO.L> sank 2.9 percent.
On the upside, German chipmaker Infineon <IFXGn.DE> jumped 5 percent after Nokia's chief executive told a newspaper that the handset maker had reached high volumes in single-chip mobile phone sales.
And Spanish utility Union Fenosa <UNF.MC> topped percentage gainers in Europe with a 5.5-percent rise after construction group ACS <ACS.MC> said that several firms were interested in its Fenosa stake. (Editing by Louise Ireland)
