| 20110000826 | METHOD AND DEVICE FOR EXTRACTING NON-MAGNETIC ORES - In a device and a method for extracting non-magnetic ores from a pulp comprising non-magnetic ore particles and having a solid fraction of at least 30 mass percent, the pulp flows continuously through a reactor in the direction of flow and magnetic or magnetizable magnet particles that form ore magnetic particle agglomerations with the non-magnetic ore particles are added to said pulp. The ore magnetic particle agglomerations are moved by a magnetic field into an accumulation range of the reactor, and are then discharged out of reactor range and separated into ore and magnetic particles. In a device and a method, the separated magnetic particles are treated, in particular hydrophobized, such that during a new interaction with non-magnetic ore particles, new ore magnetic particle agglomerations are formed. Accordingly, a high yield of ores can be obtained and the mine can be operated in an economical and environmentally friendly manner. | 01-06-2011 |
| 20110020170 | METAL NANOPARTICLES STABILIZED WITH DERIVATIZED POLYETHYLENEIMINES OR POLYVINYLAMINES - The invention relates to metal nanoparticles and a process for the preparation thereof, in which a metal salt solution is reduced with a reducing agent in the presence of the derivatized polyethyleneimines or polyvinylamines. Metal salt solutions of two or more different metals can be reduced simultaneously or in succession, metal nanoparticles comprising two or more different metals being obtained. Preferred metals are silver, palladium, and platinum. Suitable reducing agents are, for example, formic acid, formaldehyde, diethanolamine, 5-pentenoic acid and sodium borohydride. Silver can be used in the form of silver oxide and/or silver nitrate, palladium in the form of alkali metal tetrachloropalladate or palladium(II) nitrate and platinum in the form of alkali metal tetrachloroplatinate or tetraamineplatinum(II) nitrate. | 01-27-2011 |
| 20110120919 | INORGANIC PARTICLES COMPRISING AN ORGANIC COATING THAT CAN BE HYDROPHILICALLY/HYDROPHOBICALLY TEMPERATURE CONTROLLED - The present invention relates to a process for separating at least one first material from a mixture comprising this at least one first material and at least one second material, which comprises the following steps:
| 05-26-2011 |
| 20110120954 | SELECTIVE MATERIALS SEPARATION USING MODIFIED MAGNETIC PARTICLES - The present invention relates to a process of the invention for separating at least one first material from a mixture comprising this at least one first material and at least one second material, which comprises the steps:
| 05-26-2011 |
| 20110127201 | MODIFIED HIMS PROCESS - The present invention relates to a process for separating at least one first material from a mixture comprising this at least one first material and at least one second material using magnetic particles with which the at least one first material agglomerates. | 06-02-2011 |
| 20110163278 | MODIFIED PARTICLES AND DISPERSIONS COMPRISING THESE - The present invention relates to particles which have been modified by a modifier and a dispersion medium comprising the modified particles. | 07-07-2011 |
