    摘要： A solar powered pumping system has a ground level walking beam pumping unit and a downhole pump unit which pump liquids during daylight hours. The walking beam pumping unit has a solar powered electric motor which drives a flywheel through drive wheels and a centrifugal clutch to pivot a fulcrum beam having counterweights at one end. The other end of the fulcrum beam is connected by a lift wire to the downhole pump. The downhole pump has a pump housing with a stationary check valve at its upper end connected to a supply conduit extending to the surface. A traveling check valve/piston inside the pump housing is moved on the up stroke by a lift rod slidably mounted on the exterior of the housing which has a top end connected to the lift wire and a lower end connected to the traveling check valve/piston through a longitudinal slot in the lower housing. The traveling check valve/piston is returned on the down stroke by a tension return spring connected between the traveling check valve/piston and the pump housing. On the down stroke the traveling check valve opens and the stationary check valve at the top of the pump housing closes allowing liquid to enter. On the up stroke the traveling check valve closes, the stationary check valve opens, and the traveling check valve/piston lifts or pushes the liquid through the stationary check valve and subsequently to the surface. The return spring and counterweights produce a relatively balanced load condition to reduce power consumption and increase operating efficiency.

    摘要： A method for concurrently transporting and leaching metal values from an ore or concentrate containing said metal values from an originating site such as an elevated site to a delivery site comprising the steps of crushing and/or grinding the ore or concentrate to form a particulate having a size range suitable for transport by gravity or a combination of pumping and gravity as a solid constituent in an aqueous slurry, forming an aqueous slurry of from about 30 to about 70 percent by weight of said particulate in an aqueous medium, and adjusting said aqueous slurry to contain an effective amount of a lixiviant for dissolution of said metal values into the aqueous medium. The aqueous slurry with lixiviant is transported in an elongated pipeline under a static pressure and for a residence time sufficient for dissolution of a substantial portion of the metal values, and the aqueous medium with the metal values is separated from the solids constituent of the slurry by a hydrocone, settling tank, thickener, lagoon, pond or heap, or counter-current decantation or washing circuit for recovery of values therefrom. The ore or concentrate may contain metal oxides, metal sulphides, native metal or a combination thereof, such as for example, a copper oxide concentrate or an ore, and the lixiviant may be sulphuric acid.
