Abstract
240,799. Franz, T. Oct. 1, 1924, [Convention date]. Grant of Patent refused. Washing-plant, arrangement of; flotation processes.-In the wet preparation of coal. lignite, &c. the material is washed to remove sludge prior to the wet mechanical classification proper, and in the succeeding stages the sludge and levigated material are kept separate. The washed coal and sludge are separated by means of screens, and the wet sludge is subjected to flotation, while the coal is separated into two sizes and passed on to jigs. The dross waters from the flotation treatment may be subjected to classification, and salts removed to recover a serviceable water for washing the sludge out of coal. Preparation of the levigated material is effected by known processes having their own separate water circuits, and the waters are subjected to the usual clarification. If the main product be small coal, the large coal may first be disintegrated, sludge being washed out subsequently.
