ABSTRACT:
A method and apparatus for solar heating a leach solution prior to its distribution over an ore heap. The apparatus includes a distribution mat having a series of individual emitter tubes joined by heat absorbing panels. The heat absorbing panels collect and transfer the absorbed solar energy to the leach solution passing through the emitter tubes. The temperature of the leach solution passing through the emitter tubes is elevated above ambient prior to the leach solution percolating down through the ore heap. The distribution mat formed by the plurality of emitter tubes and heat absorbing panels is formed from a flexible material, thereby allowing the distribution mat to be rolled and unrolled during application to the ore heap.
