Title: Method of removing fluorine from processing liquid used in wet zinc smelting
Inventor: KATO MASAKI
IPC: C25C1/16
Filed: 2007-02-15
Abstract: <P>PROBLEM TO BE SOLVED: To efficiently adsorb and remove fluorine so that fluorine does not accumulate in liquid when using zinc-containing matters such as crude zinc oxide containing fluorine in a wet zinc smelting process.  <P>SOLUTION: The problem can be solved by making fluorine ions and ferric ions to co-exist in a sulfuric acid solution, neutralized the solution to produce iron precipitate and removing the fluorine through adsorption to and coprecipitation with the iron precipitate. In order to make the most of the capacity of elemental iron as a fluorine adsorbent, the fluorine-adsorbing iron precipitate is redissolved and used as an iron raw material for adsorbing fluorine for a plurality of times. By utilizing undissolved residues produced in the zinc smelting process as an iron raw material serving as an adsorbent and using fluorine-containing crude zinc oxide etc. as a neutralizer, the purpose can be accomplished through only the operations generally conducted in the wet zinc smelting process, i.e. dissolving, neutralization and solid-liquid separation, without requiring a large capital investment.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Therefore, though both wheels are locked by one lock, a wire for controlling a key is unnecessary to resolve complication. By locking while locking a cover of the lock, the lock cannot be disassembled without a key, so that the brake wires of both wheels need to be cut for stealing the bicycle. If cutting the wires, normal traveling of the bicycle becomes impossible, so that anti-theft effect against riding for a moment can be improved.  <P>COPYRIGHT: (C)2008,JPO&INPIT
