  • Heap Leach or CIL or Maybe Both

    14.07.2020Typically gold mines consist of either a heap leach (HL) operation or a CIL type plant. There are a few projects that operate (or are considering) concurrent heap leach and CIL operations. Ultimately the mineral resource distribution determines if it makes economic sense to have both. This blog discusses this concept based on past experience.
