Title: Wet gravitational classification method
Inventor: KITAZAWA ATSUJI
IPC: B03B5/30
Filed: 1989-12-05
Abstract: PURPOSE:To enhance classification efficiency by allowing a suspension prepared by dispersing particles to be classified in a light liquid to be present on the upper side of the heavy liquid layer and settling particles having a large particle size in a heavy liquid and separating the light liquid layer containing particles having a small particle size and the heavy liquid layer containing the particles having a large particle size. CONSTITUTION:A non-compatible heavy liquid (e.g. water) and a light liquid (e.g. isopropyl alcohol) are used to classify particles having specific gravity higher than that of the heavy liquid. At this time, a suspension prepared by dispersing particles to be classified in the light liquid is allowed to be present on the upper side of the heavy liquid to settle particles having a large particle size in the heavy liquid and, thereafter, the light liquid layer containing particles having a small particle size and the heavy liquid layer containing particles having a large particle size are separated to perform classification. As a result, the particles to be classified can be efficiently classified with a reduced number of times of decantation and classification efficiency can be enhanced and classification accuracy can be improved.
