20140026713 | REFINING OF PLATINUM GROUP METALS CONCENTRATES - 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. | 01-30-2014 |

20110300379 | METHOD FOR PRODUCING A FILAMENT YARN FROM AN AROMATIC POLYAMIDE - A method for producing a filament yarn from a para-aromatic polyamide, having an optically anisotropic aramid spinning solution filtered within a spinneret arrangement by using a filter having passage openings and extruded within the spinneret arrangement through a plurality of spinning orifices. The extruded anisotropic aramid spinning solution is guided via an air gap, stretched in the process, and collected in an aqueous coagulation bath. The optically anisotropic aramid spinning solution in the spinneret arrangement is fed to the spinning orifices via a flow resistor. The flow resistor is arranged closer to the spinning orifices than the filter, and the flow resistor and the filter are arranged at a distance to one another. The method may also include a para-aromatic polyamide filament yarn. | 12-08-2011 |
20130009337 | PROCESS FOR SPINNING GRAPHENE RIBBON FIBERS - A graphene ribbon fiber manufacturing process, where a coagulation medium flows in the same direction as the graphene ribbon fibers. The process for spinning graphene ribbon fibers starts with unzipping carbon nanotubes to form graphene ribbons, purifying and drying the graphene ribbons and subsequent dissolving of the graphene ribbons in a suitable solvent, preferably a super acid to form a spin-dope. The spin-dope is spun such that the accrued fibers are guided into a coagulation medium, also known as anti-solvent, where the spun or accrued fibers are coagulated. The coagulated graphene ribbon fibers are stripped, neutralized and washed and wound on bobbins. | 01-10-2013 |
