Abstract: Alkaline oxidation process for treating refractory sulfide ore or concentrate particles enriched in a metal to be recovered comprising stages in which refractory ore or concentrate particles are surface-oxidized in an alkaline oxidation step in alkaline liquid phase with calcium hydroxide forming an alkaline slurry, which slurry is thereafter mechanically activated to remove passivating coatings from the surface oxidized refractory ore particles.

Abstract: A process for recovery of one or more elements, selected from precious metals and chalcophile metals as herein defined, from materials containing precious and/or chalcophile metal/s, said process including: (i) a leaching step comprising contacting the material with an acidic solution containing a lixiviant comprising an aqueous amino acid-thiourea compound formed from an amino acid (as herein defined) and thiourea (as herein defined), in order to form a leachate containing the precious metal and/or chalcophile metal; and (ii) a recovery step comprising recovering the precious metal and/or chalcophile metal from the leachate.

Abstract: A process for recovery of metal comprising copper and/or a precious metal from a metal containing material, including the steps of: leaching the metal containing material with an alkaline lixiviant and an amino acid or derivative thereof in order to produce a metal containing leachate; and extracting the metal from the leachate.

Abstract: The present invention provides a peptide which: (i) consists of 10 to 16 amino acids; (ii) has at least 8 cationic amino acids with either (a) a side chain comprising a guanidinium group, or (b) a side chain comprising an amino group, of which no more than 7 are consecutive; and (iii) has 2 or 3 tryptophan residues which are not both, or not all, consecutive, said peptide optionally in the form of a salt, ester or amide, or a peptidomimetic of said peptide. The invention further relates to pharmaceutical compositions containing these compounds, the use of these compounds in therapy, particularly as anti-tumor (e.g. anti-lymphoma) agents and non-therapeutic uses of these compounds.

Abstract: A system, method, and computer program product are provided for creating metadata-based search queries. In use, a plurality of data objects in one or more databases are identified. Additionally, a plurality of attributes associated with each of the plurality of data objects are identified (e.g. attributes from a table, derived attributes, etc.). Further, a plurality of relationships associated with each of the plurality of data objects are identified. In addition, at least one of the plurality of data objects, the plurality of attributes, or the plurality of relationships are filtered to generate a first subset of data objects, a first subset of attributes, and a first subset of relationships. At least a metadata representation of at least a portion of the first subset of data objects, the first subset of attributes, or the first subset of relationships is displayed utilizing a user interface.

Abstract: A system, method, and computer program product are provided for providing validation of network model objects within a network model design process. In use, a request to create a design of at least a portion of a network model is received via an interface utilized for creating a network model design. Additionally, at least one object of the network model capable of being utilized to create the design of the at least a portion of the network model is identified, in response to the request. Furthermore, it is determined whether at least one discrepancy has been identified for the at least one object. Moreover, a response to the request to create the design of the at least a portion of the network model is provided that is based on the determination of whether the at least one discrepancy has been identified for the at least one object.

Abstract: This invention relates to a process in which a Platinum Group Metal (PGM)-rich residue from a BMR (Base Metals Refinery) process is subjected to a high temperature roast to remove contaminants, typically volatile elements (for example Se, Te, As, S, Bi, Os) and obtain a roast product. The roast product is smelted with a flux to form a slag phase and an alloy phase, and to vaporize sulphates and heavy metals like Pb, Te, and remove stable oxide compounds such as Si02 and oxides of Fe, Ni, Co, Cu, Cr, Te, Bi to the slag phase. The alloy and the slag phase are separated, and the alloy phase is then melted and atomized with a gas or liquid atomization process to form fine alloy particles that can be dissolved in water and treated in a hydrometallurgical PMR (Precious Metals Refinery) process.
