LONDON, Oct 28 (Reuters) - Gold prices fell to a three-week low in Europe on Wednesday, breaking through technical support above $1,030 an ounce, as the dollar index <.DXY> firmed, denting interest in the precious metal as an alternative asset.
Gold is also suffering from weakness in physical demand, with the world's largest gold exchange-traded fund reporting a second daily outflow on Tuesday, and a pick-up in scrap supply returning to the market, dealers said.
Spot gold <XAU=> was bid at $1,026.70 an ounce at 1653 GMT, against $1,038.80 late in New York on Tuesday. Earlier it touched a low of $1,026.60 an ounce.
"We know there is an increase in scrap supply, we know that jewellery demand is weak, and we know that ETF demand has flattened off," said HSBC analyst James Steel.
"So the odds were that we would get some sort of a correction, and clearly it has been fostered by the dollar recovery."
He said gold was likely to continue to mirror the dollar. "Our dollar view is that this is a correction rather than a change, and we are still positive on the euro, which would imply that there will be limited downside to gold," he said.
U.S. gold futures for December delivery <GCZ9> on the COMEX division of the New York Mercantile Exchange fell $7.70 to $1,027.70 an ounce.
Gold is under pressure from a rise in the dollar index, which gauges the unit's performance versus six major currencies. The dollar has benefited from a slide in global stock markets, which prompted traders to cut risk exposure. [

TEXTBOOK
Analysts say this week's gold price correction is unsurprising, given the strength of its upward move since early September, which took the metal to a record $1,070.40.
Calyon metals analyst Robin Bhar said while interest in physical gold jewellery and ETFs was waning, possibly supporting the case for a further pullback, both this and the dollar rebound looked to be temporary.
"All the longstanding bull factors for gold -- inflation, dollar weakness, unhappiness with the monetary system as it stands and what governments are doing to their paper currencies -- are still there," he said. "The uptrend remains intact."
Physical gold demand remains relatively lacklustre, with the largest gold ETF, New York's SPDR Gold Trust <GLD>, reporting a second consecutive daily outflow on Tuesday. [
]Gold buyers in India, the world's biggest bullion consumer last year, trickled in as falling prices sparked some bargain hunting, but a weak rupee dented buying interest. [
]Among other precious metals, spot silver <XAG=> was the biggest faller, as losses in gold pressured it to a three-week low of $16.14 an ounce against $16.65.
Platinum <XPT=> was at $1,298.50 an ounce against $1,312, having hit its lowest since Oct. 6 at $1,297, while palladium <XPD=> was at $317.50 against $325.50.
The metals are being supported by supply concerns in major producer South Africa and hopes demand from carmakers, the main buyers of platinum and palladium, will improve. (Editing by Sue Thomas)
