Over a period of time, the group extracted approximately 3.2 tons of gold, equivalent to roughly 38% of the mine's annual production.

[12] Several protests have been held in Bor in eastern Serbia over excessive air pollution that has been intensified since Zijin took over copper miner Rudarsko-Topioničarski Basen (RTB) in late 2018.

[13] Since January 2019, Bor has been struggling with excessive air pollution, with sulfur dioxide (SO2) levels topping 2,000 micrograms per cubic meter, up from the maximum allowed 350.

Protesters demanded that the city government urgently adopt a plan so that the line ministry and state inspectorates can react to the alarming pollution levels in Bor.

However, control a few months later, in August, showed another omission – Zijin did not have a system for wet dust removal during the transportation of tailings on the Bor mine, which also threatened human health and the environment.

Zijin was ordered to solve the problem, and the company later told the Ministry that a dust suppression system had been installed, which was put to trial.

[14][15] In January 2025, subsidiaries of Zijin Mining were banned from importing to the United States under the Uyghur Forced Labor Prevention Act.
