ABSTRACT:
An apparatus for distributing fluid onto a hydrometallurgy leach field consists of individual modules having structure for operatively coupling the modules to one another to form the apparatus. Each module, which alone can form a fluid distribution apparatus, includes a frame and an elongated reel assembly on which a plurality of individual distributors, such as perforated hoses, are carried at axially spaced positions along the elongated reel assembly. A fluid supply conduit carries fluid from a fixed fluid supply line through the elongate reel assembly to each of the hoses carried on the elongated reel assembly and to an adjacent module. The frame is supported at its ends by frame translating mechanisms, preferably endless track crawler units, which serve to selectively move the apparatus forward and rearward. Adjacent modules are coupled at respective ends thereof to a common frame translating mechanism, thus coupling the adjacent modules to one another. To distribute fluid onto the leach field, the apparatus is moved forward over the leach field heap while simultaneously unrolling the plurality hoses to deploy the hoses in a closely spaced parallel arrangement over the leach field heap. With the hoses deployed, fluid is run through the hoses and out of the perforations thereof and onto the leach field surface. After leaching is complete, the hoses are then rolled onto the elongated reel assembly and the apparatus is moved to a different part of the leach field to re-deploy the hoses.
