摘要： Molten pitch, such as obtained in petroleum refining, is comminuted as such in the presence of water to obtain coarse pitch particles solidified during the comminution by contact with the water. The coarse pitch particles are further pulverized in the presence of water and, preferably, a dispersant to form a slurry containing the finely pulverized pitch particles dispersed in the water.

摘要： Provided is a method of removing particles having a size of less than 10 .mu.m from an aqueous solution. The pH of the aqueous solution is first adjusted to be less than 9 and then the aqueous solution is passed through an absorbent of mineral fiber, containing 35 to 65 wt % of SiO.sub.2 and 65 to 35 wt % of at least one oxide selected from the group consisting of MgO, CaO, Al.sub.2 O.sub.3 and FeO. The particles in the aqueous solution adhere to the absorbent and are separated from the aqueous solution. The absorbent is regenerated by passing a descaling solution having a pH greater than 10 through the absorbent. The particles are recovered as a concentrated solution.
