20090074640 | SILICA REMOVAL FROM PREGNANT LEACH SOLUTIONS - The present invention relates generally to a process for removing dissolved or colloidal silica from a pregnant leach solution (“PLS”). More particularly, an exemplary embodiment of the present invention relates to a process which mixes PLS with an acid source, preferably lean electrolyte, to induce formation of colloidal silica that can then be collected and removed. Additionally, in an exemplary embodiment of the present invention, at least one silica seeding agent is added to induce formation of colloidal silica, at least one flocculant is added to induce aggregation of the colloidal silica, and a solid-liquid separation process is utilized to remove advantageous amounts or substantially all of the colloidal silica, thereby providing relief from supersaturation of dissolved silica in the metal recovery processes. | 03-19-2009 |
20090183997 | METHOD AND APPARATUS FOR ELECTROWINNING COPPER USING AN ATMOSPHERIC LEACH WITH FERROUS/FERRIC ANODE REACTION ELECTROWINNING - The present invention relates, generally, to a method and apparatus for recovering metal values from a metal-bearing materials, and more specifically, a process for recovering copper and other metals through leaching, electrowinning using the ferrous/ferric anode reaction, and the synergistic addition of ferrous iron to the leach step. | 07-23-2009 |

20140208170 | METHOD FOR MONITORING A GRAPHICAL USER INTERFACE ON A SECOND COMPUTER DISPLAY FROM A FIRST COMPUTER - A high level interface between a remote computer and local computer operator permits the remote computer to be controlled via a sequence of interactions. The remote computer may be monitored for display information which is expected, and also controlled in the event the expected information either is or is not obtained. Command language extensions are provided which extend and complement a basic scripting language. Scripts with embedded command language extensions may be executed through a remote interface, permitting remote testing, operation and evaluation. The development of the scripts, including embedded command language extensions, may be prepared through execution of commands at the local computer on a depiction of the GUI received from the remote computer, and subsequently saved as a script. | 07-24-2014 |
