How does a land dredge work for gathering gold

The IPAAM said in a statement that the rafts anchored on the river were under federal jurisdiction, so the National Mining Agency (ANM) was responsible for licensing and it was up to the federal police to see if any crimes had been committed. The dredging rafts have floated downriver from the Humaita area, where there has been a surge in illegal gold mining, and were last seen some 650 km away in Autazes, a municipal district southeast of Manaus.Ī spokesperson for Brazil’s environmental protection agency Ibama said the illegal dredging on the Madeira river was the responsibility not of the federal government but of Amazonas state and its environmental agency IPAAM. The Madeira flows some 3,300 kilometres from its source in Bolivia through the rainforest in Brazil and into the Amazon River.

However, far-right President Jair Bolsonaro has weakened environmental enforcement since taking office in 2019, turning a blind eye to invasions of protected public and indigenous lands by illegal loggers, cattle ranchers. The gold rush, triggered by rumors that someone had found gold there, began as world leaders gathered for a United Nations climate conference in Glasgow, where Brazil vowed had stepped up protection of the Amazon rainforest. They’ve been there at least two weeks and the government has done nothing,” said Greenpeace Brazil activist Danicley Aguiar.
