Abstract
A rotatable leaching solution distribution arm is carried on a central chamber member and disposed in a tank at an elevation above another rotatable arm also carried by the member for distribution of a washing solution into the tank. The leaching solution distribution arm has discrete conduits terminating in corresponding outlets along the arm together with flow control devices accessible externally of the tank for each conduit so that the flow from each outlet into the tank can be monitored and adjusted.
