LONDON (Dow Jones)--Miners moved higher in London on Tuesday, as gold futures headed back above $1,000 an ounce, with the move guiding the top index back toward a key level.

Mining companies making gains included Rio Tinto (RTP), up 3.6%; BHP Billiton (BHP), up 2.6%; and Anglo American , up 1.5%.

The move came as gold futures surged above $1,000 an ounce on Tuesday, propelled by weakness in the U.S. dollar.

Gold for December delivery, the most active contract, rose $7 to $1,003.70 an ounce. It's the first time a front-month contract has traded above $1,000 since February.

The dollar continued to lose ground against the euro and sterling, with the sterling up 1.2% at $1.6530 against the greenback following some surprisingly strong manufacturing output data.

"Increased risk appetite [has] dominated proceedings after the weekend G20 meetings. Risk has also become more attractive due to the return of M&A," said James Hughes, trader at CMC Markets.

Bid target Cadbury rose another 0.4% to 786 pence on Tuesday, extending sharp gains from Monday when Kraft Foods Inc. (KFT) offered 745 pence a share to buy the chocolate maker.

"We think that, given the attractiveness of Cadbury as an asset, other bidders such as Nestle/Hershey and PepsiCo may emerge," said analysts at Investec Securities.

Overall, the U.K. FTSE 100 index closed up 0.3%, or 14.16 points, to 4,947.34 in the third straight day of gains for the index.

Other European shares were also higher, as were U.S. stocks as traders returned from a long holiday weekend.

Turning to telecoms, Vodafone Group (VOD) shares rose 1.7% in the top index.

Rival Deutsche Telekom said Tuesday that it plans to merge its T-Mobile U.K. division with France Telecom's (FTE) Orange U.K. unit in a 50:50 joint venture that is expected to have a 37% share of the U.K. mobile market.

"Consolidation in the U.K. is good news for all players. Obviously the buyer gets the cost synergies, but all market participants benefit from a more rational environment," said analysts at Iberian Equities.

Meanwhile, shares of home-improvement retailer Kingfisher rose 0.5% after the firm rushed out "indicative" interim figures following a leak on Monday afternoon.

Kingfisher said that it expects adjusted pretax profit in a range of 285 million pounds ($466 million) to 290 million pounds for the six months ended Aug. 1. A year earlier, the firm posted adjusted pretax profit of 214 million pounds.

"We had expected first-half pretax profit of 'only' 271 million pounds, up 27% on last year, so today's news is pleasing and is driven by an approximate 20 million pound beat on B&Q profits," said Nick Bubb, analyst at Pali International.

Other retailers advancing in London included Marks & Spencer , up 3.3%; Home Retail , up 0.7%; and Next , up 1.9%.

Barclays (BCS) shares declined 1.1%. The U.K. financial regulator said Tuesday that it fined Barclays 2.45 million pounds ($4 million) for failing to provide accurate details on millions of financial transactions.

InterContinental Hotels (IHG) rose 5.5% after Credit Suisse upgraded the hotels operator to outperform from neutral, saying it will benefit from a recovery in revenue per available room.

Whitbread extended Monday's rally with a 3.9% rise as Credit Suisse also upgraded the Premier Inn and Costa Coffee operator.

Also outside the FTSE 100, shares of DS Smith climbed 12.7% as the packaging group reported a better-than-anticipated start to the fiscal first quarter after slower erosion in selling prices and a faster reduction in operating costs.

It cautioned that it remains concerned about the level of demand across the majority of its market sectors, and that input-cost increases are above expectations, so it is too early to be certain that this better first-quarter performance will be sustained for the full year.
