Ecuador to tighten rules for mining waste dams to avoid repeat of Brazil disaster

Ecuador’s government plans to tighten rules regulating the construction and operation of mining waste dams to avoid disasters like one in Brazil in January when a dam owned by Vale collapsed, killing hundreds.

Vice Minister of Mining Fernando Benalcazar told Reuters the new rules will take effect in December and will prohibit the building of so-called tailings dams close to populated areas and ban certain designs that are considered less stable.
