* Platinum off lows on bargain hunting (Updates prices to afternoon)

SINGAPORE, Aug 8 (Reuters) - Gold tumbled to an 8-week low in volatile trade on Friday, losing some of its shine as an alternative investment after the dollar jumped against the euro, prompting some investors to switch funds back into currencies.
Platinum bounced off lows but fears of supply curbs following a one-day strike in main producer South Africa subsided. Silver was down, while palladium still attracted bargain hunting after falling to its lowest level in eight months this week.
Gold <XAU=> hit a high of $873.50 an ounce before dropping back to $868.80/869.80 an ounce, down $871.05/872.45 an ounce late in New York. The metal also hit an intraday low of $866.25 an ounce, an 8-week trough, on selling pressure from the rising dollar.
"In the absence of commodity-type news, I think the market is probably going to be weaker. I think it's mainly dollar-dominated today," said Mark Pervan, an ANZ senior commodity analyst.
"I think around $850 would be a critical level," said Pervan, who pegged resistance at $900.
Gold has dropped more than 15 percent in value since spiking to a record high of $1,030.80 hit in March.
The euro fell as far as $1.5195, a five-month low, after European Central Bank President Jean-Claude Trichet cooled expectations for an interest rate hike by sounding a note of concern over the slowing euro zone economy. [
]"People get out of the market. Jewellery makers are waiting for a good time to buy, so actual demand is not so good. The same goes for platinum," said Yukuji Sonoda, a precious metals analyst at Daiichi Commodities in Tokyo.
"I had thought gold will stabilise at $900. People are disappointed," he said.
Spot platinum <XPT=> rose to $1,576.00/1,596.00 an ounce from $1,572.00/1,592.00 late in New York on bargain hunting after falling as low as $1,564.50 an ounce earlier in the day.
Eearly bargain buying from speculators in Tokyo futures helped trigger gains in the cash market but dealers said automakers remained on the sidelines.
"As for platinum, $1,550 may be the next target. If you compared with Johnson Matthey's forecast, this is incredibly cheap," said Sonoda of Daiichi Commodities.
Platinum prices have taken a dramatic turn since spiking to a record high at $2,290 an ounce in early March, losing much of their gains to profit taking and a slowing U.S. economy that threatens to slash demand for autocatalysts.
The current price was well below the target of $2,500 forecast in May by Johnson Matthey <JMAT.L>, the world's largest platinum refiner and distributor, citing output shortfalls and strong demand.
The bulk of the world's platinum is used by automakers in autocatalyst systems that scrub exhaust fumes of dangerous and environmentally-damaging chemicals.
The most active Tokyo platinum contract for June 2009 delivery <0#JPL:> on the Tokyo Comodity Exchange fell 23 yen per gram to 5,532 yen -- off an intraday high of 5,556 yen.
New York gold futures <GCZ8> fell $0.7 to $877.20 an ounce.
Spot palladium <XPD=> rose to $345.00/350.00 an ounce from $344.00/352.00 late in New York. Silver <XAG=> edged down to $16.09/16.16 an ounce from $16.14/16.23.
