Abstract: The present invention relates, on one hand, to a metal cementing apparatus (1) formed by a vessel (2) with a liquid phase formed by a solution (3) containing noble metal, and a solid phase formed by a cementing metal or a less noble metal in contact with the solution (3), where one of said phases moves at a high speed with respect to the other one, and the difference in speeds allows the cementation of the noble metal on the solid phase, and the simultaneous detachment and separation thereof, and comprises means for generating the movement of at least the phase with the high speed and removing means for removing the precipitated noble metal.

Abstract: A method of extracting metals from polymetallic sulphide ores or concentrates comprising at least Cu, Zn, Pb and Ag, comprising a first step of atmospheric leaching in sulphate medium in the presence of recycled silver for extracting Cu and Zn and a second step of atmospheric leaching in chloride medium for extracting Pb and Ag.

Abstract: An accessory for the matching of garments is provided that includes a strip of a flexible material having first and second ends with a fastening element at each end. The fastening elements are preferably in the form of clamps. The fastening elements and the strip may be colored and made of a material that does not damage the garments. The strip may also include cooperating elements intermediate its ends for securing the strip in a folded condition.
