ABSTRACT:
An apparatus for applying a leaching solution to a mass of ore includes a plurality of first tubes which are connected to a supply of leaching solution. Each of the first tubes is fitted with emitters which are positioned at spaced intervals along the length of each first tube. The first tubes are connected with a manifold on their distal ends. A second tube is connected to the manifold. The second tube is fitted with a sprinkler which is positioned to distribute leaching solution over the surface area of the ore mass which is positioned intermediate adjacent emitters.
