Cliente Confidencial - Brasil

Tierra Group fue contratada para realizar la debida diligencia metalúrgica en dos propiedades operativas y dos prospectos en el desarrollo de la etapa inicial. Las dos operaciones existentes consistieron en una lixiviación en pilas convencional, seguida de ADR para producir un Dore en el sitio y una molienda convencional, CIL, ADR para producir Dore en el sitio.

Las dos oportunidades futuras consistieron en un recurso de óxido con un diagrama de flujo de producción de concentrado, flotación y molienda convencional propuesto. El segundo era un recurso subterráneo con una mineralización compleja de carbonato/arsénico que requiere un diagrama de flujo bastante complejo. Este diagrama de flujo se revisó con el personal metalúrgico del sitio y se identificaron varios desafíos que requerirán confirmar las pruebas adicionales. Se ofrecieron y discutieron soluciones alternativas, así como pruebas recomendadas.
