Thousands protest in Serbian capital against lithium mine

Thousands hit the streets in Serbia's capital Belgrade Saturday to protest the rebooting of a controversial lithium mine set to serve as a vital source to power Europe's green energy transition.

Ahead of the rally, two leading protest figures said they were briefly detained by security officials who warned that any moves to block roads during the protest would be seen as illegal.

Thousands chanted "Rio Tinto get out of Serbia" and "You won't dig" as they rallied in downtown Belgrade before setting off on a march through the city. Protestors later entered the Belgrade's main railway station where demonstrators blocked tracks, halting traffic.

Serbia has vast lithium deposits near the western city of Loznica, where a mining project being developed by the Anglo-Australian mining giant Rio Tinto has been a perennial political fault line in the Balkan country in recent years over its potential environmental impacts. The deposits were discovered in 2004, but weeks of mass protests forced the government to halt the project in 2022.

The government revived the project following a court decision last month that said the order to revoke the permits awarded to Rio Tinto was "not in line with the constitution and the law". The Serbian government signed a memorandum of understanding with the EU that is seen as the first step in developing Serbia's lithium resources.

Lithium is a strategically valuable metal needed for electric vehicle batteries, making it key for helping the automotive industry shift to greener production. The project, however, has continued to be unpopular with many in Serbia due to concerns the mine would pollute water sources and endanger public health.

"I am in Belgrade because the survival of life in Serbia is being defended here," said Slobodan Stanimirovic, 58, from western's Serbia's Radjevina near the site of the future mine.

The protest in Belgrade was the latest in a series of demonstrations held across the Balkan country after the mine's licenses were reinstated.

Activists and demonstrators have called on legislators to pass a law permanently banning the mining of lithium and boron in Serbia.

Environmental groups said they were prepared to block major traffic arteries across Serbia and engage in civil disobedience if the government refused to act before an August 10 deadline set by activists.
