LONDON, July 29 (Reuters) - Gold eased in Europe on Wednesday as the dollar firmed, prompting losses across commodities, with currencies seen as higher risk coming under heavy selling pressure after recent gains.
The precious metal has risen from a low of $932.70 an ounce, however, as the dollar pared gains after European markets reversed initial losses to tick higher.
Spot gold <XAU=> was bid at $936.35 an ounce at 0822 GMT, against $936.65 an ounce late in New York on Tuesday. U.S. gold futures for August delivery <GCQ9> on the COMEX division of the New York Mercantile Exchange slipped $2.50 to $936.60 an ounce.
Precious metals fell along with many other commodities, such as oil, copper and zinc, after a 5 percent slide in Chinese equities dented risk appetite and lifted the dollar against a basket of currencies. [

"If you have wobbles over China, the dollar picks up, and commodities come off," he said.
Chinese stocks dropped 5 percent on Wednesday, their biggest daily drop in eight months, amid worries banks were set to restrict lending. European shares also opened lower, though they later clawed back losses. [
]Oil prices slid nearly 2 percent, while industrial metals such as copper and zinc also posted losses. [

SLOW DEMAND
Investment demand for gold remained lacklustre, with a further 3.36-tonne outflow from the world's largest bullion-backed exchange-traded fund, the SPDR Gold Trust <GLD>, adding to a recent retreat in ETF holdings. [
]Physical demand for gold remains soft overall, with seasonal weakness and high prices hurting consumption in the key Indian and Middle Eastern markets. This weakness in underlying demand makes gold vulnerable to a sell-off, analysts said.
"Given the recent build in speculative longs and ETF redemptions yesterday, combined with very limited physical interest, gold remains vulnerable to a deeper correction," said James Moore, an analyst at TheBullionDesk.com, in a note.
On the supply side, Russia's Polyus Gold <PLZL.MM> said its output of the precious metal fell 14 percent year-on-year in the first half, due to declining ore grades. [
]Among other precious metals, platinum <XPT=> was at $1,187.50 an ounce against $1,192.50 late on Tuesday, while palladium <XPD=> was at $255 against $256.50.
The two metals climbed to multi-week highs earlier this week as firmer stocks boosted hopes demand for the autocatalyst materials would pick up. However, analysts say the uptick in the dollar is being used as an opportunity to take profits.
Silver <XAG=> was at $13.58 an ounce against $13.69.
