Disclosed are a zeolite-like material, and a preparation method and use thereof. In the disclosure, cyclic molecules of the zeolite-like material form a closed cage-like cavity structure with each other. The zeolite-like material is synthesized using an inorganic solid waste as a raw material.

A brick fabricated from a waste fiber-reinforced polymer (FRP) includes a main body. The main body is formed of a composite. The composition of the composite includes, in parts by weight, 1.0 part by weight of a plurality of furnace slag powders, 0.35 to 0.5 parts by weight of a plurality of glass fiber/polymer particles, 0.02 to 0.5 parts by weight of a plurality of glass powders, and 0.65 to 0.75 parts by weight of an alkali solution. The glass fibers/polymer particles are obtained by crushing the waste FRP. The glass powders are obtained by crushing a waste glass. The furnace slag powders, the glass fiber/polymer particles, the glass powders and the alkali solution are uniformly mixed into a mixture. The mixture is poured into a mold, and then generates a polymerization reaction to form the main body.

A mixer and a mixing unit for mixing and handling industrial side-stream materials. The mixer (6) is arranged onto a movable work machine (5) and it is used for mixing at least two side-stream materials to form a geopolymer. The mixer (6) comprises: a bucket part (27) for loading and transferring the side-stream material; a mixer apparatus (26) for mixing the side-stream material which has been loaded into the space delimited by the bucket part (27); a connecting device (25) for connecting the mixer (6) to a boom of a work machine (5); and at least one measuring device (S1, S2, S3) for determining properties of the material in the mixer (6).

An arrangement and a method for mixing and handling industrial side-stream materials. The mixer (6) is arranged onto a movable work machine (5) and it is used for mixing at least two side-stream materials to form a geopolymer. The side-stream materials are processed between a waste pile (4) and a casting area (13) in the mixer (6). Cast paste is allowed to harden and after that it is crushed to obtain an earthwork material.

A method of this disclosure directionally drills at least one well extending from ground surface to an interior of an underground mine located below ground, the well being at an oblique angle relative to vertical; blends or mixes together a hazardous material, like lead, zinc, arsenic, and cadmium with cement including a plasticizer; pumps or flows the mixture into the well, wherein the mixture flows toward a lower end of the mine and hardens in place. The method allows for the permanent placement of contaminated mixtures like chat into mines or shafts or depositories, as defined by the United States Environmental Protection Agency, CERCLA and Superfund laws and complies with rules for the permanent closing of these structures with contaminated material and contaminated substances.

The present invention relates to mechanochemically carbonated slags. The invention further relates to methods of its production and uses thereof, for example a filler. The invention further relates to compositions comprising the mechanochemically carbonated slag and a further material selected from the group consisting of asphalt, geopolymer, cement, polymers and combinations thereof and methods of their production. The invention further relates to concrete and methods of their preparation.

Disclosed are a zeolite-like material, and a preparation method and use thereof. In the disclosure, cyclic molecules of the zeolite-like material form a closed cage-like cavity structure with each other. The zeolite-like material is synthesized using an inorganic solid waste as a raw material.

A method for stabilizing a neutralization slag of uranium associated zirconium and zirconia, and a stabilization agent used therein are disclosed. The stabilization agent includes the following components in parts by weight: a pretreatment agent of 2-8 parts, anhydrous calcium chloride of 2-6 parts, an adsorbent of 3-5 parts and a stabilizer of 4-9 parts. The stabilization agent is used to stabilize the uranium that is existed in the neutralization slag in a waste slag. The method includes the following steps: the pretreatment agent is used to alkalize and disperse the neutralization slag; soluble calcium salt is added to cement the neutralization slag; and the adsorbent and the stabilizer are used as a composite material to passivate the neutralization slag. The method has low cost, fast effectiveness, simple process, easy operation, and long-term stable remediation efficiency, which can be applied to the treatment and disposal of associated radioactive waste residues.

According to the present invention there is provided a method for treating a zinc leach residue comprising the steps of: adding the zinc leach residue and a sulfide material comprising copper and flux to a furnace having a molten bath therein; operating the furnace to produce a matte comprising copper and a slag comprising zinc; separating the matte from the slag; and recovering zinc from the slag. The method preferably comprises the additional step of recovering the copper and/or other precious metals such as silver and gold, from the matte.
