There has always been an element of madness to gold's allure. For thousands of years, something in the eternally lustrous metal has driven people to the outer edges of desire - to have it and hoard it, to kill or conquer for it, to possess it like a lover. In the early 1500's, King Ferdinand of Spain laid down the priorities as his conquistadors set out for the New World. "Get gold," he told them, "Humanely if possible, but at all costs, get gold." In that long and tortuous history, gold has now arrived at a new moment of opportunity and peril.

The extravagance of the moment is provoking a storm among environmental groups and communities near the mines, and forcing even some at Tiffany & Company and the world's largest mining companies to confront uncomfortable questions about the real costs of mining gold. "The biggest challenge we face is the absence of a set of clearly defined, broadly accepted standards for environmentally and socially responsible mining," said Tiffany's chairman, Michael Kowalski. He took out a full-page advertisement last year urging miners to make "urgently needed" reforms.

Consider a ring. For that one ounce of gold, miners dig up and haul away 30 tons of rock and sprinkle it with diluted cyanide, which separates the gold from the rock. Before they are through, miners at some of the largest mines move a half million tons of earth a day, pile it in mounds that can rival the Great Pyramids, and drizzle the ore with the poisonous solution for years. The scars of open-pit mining on this scale endure.

A months-long examination by The New York Times, including tours of gold mines in the American West, Latin America, Africa and Europe, provided a rare look inside an insular industry with a troubled environmental legacy and an uncertain future. Some metal mines, including gold mines, have become the near-equivalent of nuclear waste dumps that must be tended in perpetuity. Hard-rock mining generates more toxic waste than any other industry in the United States, according to the Environmental Protection Agency. The agency estimated last year that the cost of cleaning up metal mines could reach $54 billion.

A recent report from the Government Accountability Office chastised the agency and said legal loopholes, corporate shells and weak federal oversight had compounded the costs and increased the chances that mining companies could walk away without paying for cleanups and pass the bill to taxpayers. "Mining problems weren't considered a very high priority" in past decades, Thomas P. Dunne, the agency's acting assistant administrator for solid waste and emergency response, said in an interview. "But they are a concern now."

With the costs and scrutiny of mining on the rise in rich countries, where the best ores have been depleted, 70 percent of gold is now mined in developing countries like Guatemala and Ghana. It is there, miners and critics agree, that the real battle over gold's future is being waged. Gold companies say they are bringing good jobs, tighter environmental rules and time-tested technologies to their new frontiers. With the help of the World Bank, they have opened huge mines promising development. Governments have welcomed the investment.

But environmental groups say companies are mining in ways that would never be tolerated in wealthier nations, such as dumping tons of waste into rivers, bays and oceans. People who live closest to the mines say they see too few of mining's benefits and bear too much of its burden. In Guatemala and Peru, people have mounted protests to push miners out. Other communities are taking companies to court. This month a Philippine province sued the world's fifth-largest gold company, Canada-based Placer Dome, charging that it had ruined a river, bay and coral reef by dumping enough waste to fill a convoy of trucks that would circle the globe three times.

Placer Dome, which also runs three major mines in Nevada, answered by saying that it had "contained the problem" and already spent $70 million in remediation and another $1.5 million in compensation. Some in the industry have paused to consider whether it is worth the cost - to the environment, their bottom line or their reputations - to mine gold, which generates more waste per ounce than any other metal and yet has few industrial uses.

The world's biggest mining company, Australia-based BHP Billiton, sold its profitable Ok Tedi mine in Papua New Guinea in 2001 after having destroyed more than 2,400 acres of rainforest. Upon leaving, the company said the mine was "not compatible with our environmental values." After tough lessons, other companies, like Newmont Mining, the world's largest gold producer, are paying for more schools and housing, trying harder to ease social problems around its mines.
