Abstract: A method for the heap leaching of manganese-containing ores, the method characterised by the steps of: (i) beneficiating the manganese-containing ore and separating into a coarse fraction and a fine ore fraction; (ii) combining the fine ore fraction with a sulfide ore material to produce a combined ore fraction; (iii) stacking the combined ore fraction to form at least one heap; and (iv) applying a lixiviant to the heap to produce a pregnant leach solution (PLS) containing dissolved manganese values, wherein the lixiviant is added to the or each heap in the presence of soluble iron.

Abstract: An apparatus and method are disclosed for tamper-proofing two-dimensional, optical, computer readable bar codes, including QR Codes. QR Codes, like traditional bar codes, contain computer readable content not cognizable by the human mind. The present invention teaches means of securing this content from would-be thieves and forgers motivated to overlay authorized, original content with unauthorized, replacement content.

Abstract: A method, computer program product and system are disclosed for procuring, identifying, collecting, analyzing and tracking potential buyers and investors of real property using an electronic network like the Internet. A central managing authority uses uniquely configured data processing devices and signage bearing QR Codes to induce potential buyers of real estate to electronically contact the central managing authority in manner which allows the central managing authority to track when, how and where the potential customers where induced to make contact. The disclosed method and system uniquely assist the central managing authority in the solicitation of the newly acquired sales leads to save expending inefficient amounts of time and money inherent in realizing traditional methods. Signage is printed bearing and RFID tag or two- or three-dimensional bar codes, such as a QR Code, and positioned in accordance with a predetermined criteria.

Abstract: A process for the hydrometallurgical processing of manganese containing materials, the process characterized by the combination of a manganese dioxide containing feedstock and an acidic solution to form an acidic solution to be leached, and passing a volume of sulphur dioxide gas through that leach solution as the leaching agent, whereby no sintering or roasting pre-treatment step of the feedstock is undertaken and the levels of dithionate ion generated in the leach solution are less than about 5 g/l. Also described is a process for the production of electrolytic manganese dioxide.
