Abstract

This invention relates to a method for recovering metal values from ore, including the steps of depositing two or more processed ore fractions with different particle sizes in discrete layers (16,18) to form a layered heap leach structure (10) located on a heap leach pad (12). The layered heap structure (10) is leached with a leachate which permeates by gravity through the layers, and leachate containing dissolved values is recovered from a leachate collection point or points. The invention also relates to a layered heap leach structure (10).
