Title: Method for manufacturing magnetic fluid for gravity separation
Inventor: TAIRA HIDEHARU
IPC: H01F1/44
Filed: 2003-08-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnetic fluid for gravity separation with which the magnetic fluid for gravity separation can be manufactured at low cost.  <P>SOLUTION: First iron salt and second iron salt aqueous solutions are produced from inorganic iron-containing waste and iron-containing powder using sulfric acid and nitric acid, and the aqueous solutions are heated with alkali injection to produce magnetite particles. To the particles, long-chain unsaturated fatty acid salt such as oleic acid sodium is adsorbed to reduce pH lower than or equal with 4 for aggregating and precipitating the particles, and the precipitate is diffused in a surfactant such as dodecyl benzene sulfonic acid sodium to obtain a water-based magnetic fluid for gravity separation. Thus, the first iron salt and the second iron salt aqueous solutions can be easily obtained from solid-state materials such as waste or inexpensive materials in a proper composition state, and the magnetic fluid can be manufactured at low cost. Further, gravity separation that uses a great quantity of magnetic fluids can be smoothly operated and a higher-level separation method in comparison with conventional gravity separation can be made practical for use.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
