<p><P>PROBLEM TO BE SOLVED: To provide a method for washing particulates by which washing loss of the particulates can be effectively reduced and washing efficiency is not sacrificed even when the particulates have particle size distribution. <P>SOLUTION: A material to be washed (10) which comprises the particulates (1) having particle size distribution and impurities (2) is washed by washing media (3, 3') to remove the impurities (2). By this method, the material to be washed (10) comes into contact with the washing medium (3') in a container (5) and the washing medium (3') is circulated in the container (5) from a lower side (5a) to an upper side (5b) so that ascending speed of the washing medium (3') changes in the container (5). <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
