Abstract: A computer-implemented system and method for capturing potentially obscured elements of a graphical user interface are disclosed. In one example, the method may include: generating a proxy object within an operating system, wherein the operating system includes a window manager and a graphics framework; registering a target graphical object for capture; instructing the operating system to map a copy of graphical information corresponding to the target object to the proxy object; intercepting graphical information corresponding to the target object; and storing a copy of the graphical information corresponding to the target object.

Abstract: A method of extracting zinc from a sulphidic ore is provided which comprises bioleaching the ore in a heap with acidophilic microorganisms to produce a pregnant leach solution which is recovered from the bottom of the heap. An integrated process which comprises subjecting the pregnant leach solution to neutralization and solvent extraction to produce a concentrated zinc solution is also provided. Zinc may be recovered from the concentrated solution by means of electrowinning, either in the absence or presence of manganese. Alternatively zinc may be recovered in the form of a zinc compound.
