Definitions

  • transportation step (b) may include transporting the coarse concentrate by any one or ship, rail or any other option from a given non-hub mine to a hub mine depending on factors such as (but not limited to) the availability and cost of transportation options and the locations of the given non-hub mine and the hub mine.
  • ships may be used for one or more non-hub mines and rail may be used for one or more other non-hub mines.
  • the coarse particle flotation unit may be any suitable unit.
  • the comminution units are operated so that the entire mill output stream 15 has a suitable particle size range and distribution of particle sizes for coarse particle flotation.
  • the coarse concentrate stream 19 contains a higher concentration of gold and copper than in the tailings stream 21.
  • the particle size distribution of the tailings in the coarse tailings stream 21 is coarser than the particle size distribution of tailings produced in a fines flotation unit. This means that there are less issues with tailings disposal of the coarse tailings stream 21 and ultimately mine remediation.
  • the dewatered coarse concentrate 25 is unloaded from the ship 29 at the hub mine 81 and transferred to a comminution circuit.
  • the CIL unit 71 produces gold dore and a CIL tailings stream 73.

Abstract

Un procédé de traitement d'un minerai extrait qui contient un métal de valeur comprend la production d'un concentré grossier dans une unité de flottation grossière (17) dans une ou plusieurs mines n'appartenant pas à un nœud (1) et le transport du concentré grossier vers une mine de nœud (81) et le traitement du concentré grossier dans une installation de traitement de minéraux au niveau de la mine de nœud et la production d'un produit commercialisable contenant un métal de valeur. Les résidus produits dans la ou les mines n'appartenant pas à un nœud sont des résidus grossiers à drainage libre.
