Patent number: 8486177Abstract: A method of leaching a metal value from a heap of a metal-containing ore and a heap leaching operation are disclosed. The method includes establishing a downward flow of a leach liquor through a section of the heap by supplying the leach liquor onto a top surface of the section and allowing the leach liquor (containing metal values in solution) to drain from a lower part of the section. The method is characterized by supplying the leach liquor onto the top surface of the section at a flow rate that is sufficient so that the downwardly flowing leach liquor saturates the section of the heap.Type: GrantFiled: August 2, 2012Date of Patent: July 16, 2013Assignee: Technological Resources Pty LtdInventors: Robin John Batterham, Lucy Esdaile, Raymond Walter Shaw

Patent number: 8388728Abstract: A process for leaching an ore containing sulfidic copper-containing minerals includes carrying out an aerated oxidizing leach of a part of the ore and producing an acidic leach liquor containing ferrous ions, ferric ions, and copper ions in solution. The process also includes carrying out a leach of another part of the ore using the leach liquor under conditions that minimize reactions with a source of iron in the ore and producing a leach liquor containing copper ions in solution. The process further includes recovering copper from the leach liquor.Type: GrantFiled: June 26, 2008Date of Patent: March 5, 2013Assignee: Technological Resources Pty.

Patent number: 8070078Abstract: A method and an apparatus for crushing material, particularly mined material, are disclosed. In one embodiment two or more pairs of crushing rolls successively crush mined material. The pairs of crushing rolls are arranged and operated so that an upstream pair of rolls produces a feed, preferably a pressurized feed, for a downstream pair of rolls. In another embodiment, at least an upstream pair of rolls is driven intermittently, for example, by means of a stepping motor to provide stepped rotational movement of the rolls.Type: GrantFiled: October 24, 2005Date of Patent: December 6, 2011Assignee: Technological Resources Pty LimitedInventors: Richard Anthony Bearman, Robin John Batterham, Raymond Walter Shaw
