    摘要: The present invention relates to microbiological processes for the oxidative treatment of refractory gold and base metal ores and concentrates, and specifically, to bacterial inoculums for use in such processes that are strongly resistant to thiocyanate toxicity. The present invention also relates to methods of developing and using these bacteria. The use of a bacterial inoculum with high thiocyanate resistance confers a number of technological advantages on biooxidation processes including improvements in operating flexibility, operation costs and environmental acceptability.

    摘要: The present invention is directed to microbiological processes for the oxidative treatment of refractory gold and base metal ores and concentrates, and particularly, an apparatus for testing refractory gold and sulfidic base metal ores for their suitability to heap biooxidation or bioleaching processes. The invention can be used to simulate heap biooxidation. This apparatus incorporates features of heap biooxidation and may be used to generate engineering data for creating detailed process and engineering designs. The invention can be used to develop a select population of bacteria geared to optimize biooxidation of a specific refractory ore.

    摘要: A water permeable, contoured, polymeric film which is apertured and which contains a pattern of raised areas. The film is formed from elastomeric polymer, preferably a blend of ethylene-vinyl acetate copolymer with incompatible polymer. The numbers of apertures and raised areas contained in the film are such that the ratio of apertures to raised areas is greater than unity. The apertures are preferably distributed in a random manner throughout the raised areas. Processes for forming the film by first aperturing the film and then impressing raised areas into the apertured film are also described. The film may be employed to form the body contacting surface in absorbent devices. The use of the film helps to reduce the phenomenon of wet-back.
