A radioactive waste acid is recycled. The waste acid is a fluoboric waste acid. The waste acid contains a lot of oxides and radioactive nuclei. The waste fluoboric acid is processed to obtain a purified fluoboric acid. The amount of radioactive nuclei is greatly reduced. Thus, the present invention has a simple procedure with low cost and reduced power consumption.

Method of recycling radioactive waste acid

Disclosed is a method for making a refractory material from aluminum residues of aluminum recycling. At first, the aluminum residues is mixed with adhesive solution so that the percentage by weight of the adhesive solution is 5 wt % to 10 wt %. The mixture is granulated into grains. The grains are filled in a mold, pressed and then removed from the mold so that the grains are turned into a green body. The green body is heated in a furnace at a range of temperature from 1100&#xb0; C. to 1400&#xb0; C. so that the grains are sintered and become a refractory material.

Method for producing a refractory material from aluminum residues

Slag fiber is used to fabricate a friction material. Friction factor and abrasion loss of the friction material are controlled. The friction material can be used to make linings. Thus, slag fiber can be used as a replacement for natural material to make a friction material, and waste is thus recycled.

Method of fabricating slag fiber friction material

Disclosed is a method for making fiber paper. In this method, mineral fibers and PVA resin are blended in water, thus forming first solution. Polymer fibers and PVA resin are blended in water, thus forming second solution. The first solution is mixed with the second solution. A wet paper-making machine is used to make mineral fiber paper from the mixture.

Method for making mineral fiber paper

Incinerator ashes, which is obtained after treating municipal solid waste, incinerator ashes or its plasma vitrified slag is made into mineral fibers. Cullet is added during manufacturing the mineral fibers for conditioning. The mineral fibers thus obtained have a good strength and could raise value of recycled product. In addition, it could reduce impact of the incinerator ashes to the environment and environmental protection is achieved.
