A system and method directed to the economical recovery of valuable iron constituents from iron blast furnace and steel-making slag fines wherein the slag is obtained and subjected to a series of classification steps which progressively sort the slag fines by various physical characteristics, including magnetism, size, and density, into relatively iron-rich and relatively iron-poor classifications, resulting in the isolation of iron-rich commercial byproduct at one or more of the classification steps.

An apparatus for recycling fly ash has a quantum energy generator therein. The apparatus recycles fly ash generated as the combustion waste from the burning of coal in thermal power plants, into construction materials such as cement substitutes, environment-friendly cover materials, etc. Unburned pulverized coal is removed while generating carbon monoxide (CO) or carbon dioxide (CO.sub.2) through a combustion reaction, in which the unburned pulverized coal of the fly ash contacts the thermal electrons discharged during a thermal decomposition process at a high temperature, the negative electrodes of the thermal decomposition part, which are heated at a high temperature of 500° C., which is an ignition point of the unburned pulverized coal, or higher, and a high-voltage discharge electrode of an electrochemical reaction part, then heated at 500° C. or higher, and then naturally burned under an oxygen atmosphere (oxygen or ionized oxygen ions in air contained in the fly ash).

A method and apparatus to reclaim metals from scrap material such as automobile shredder residue (ASR) that, after separating out light density components, separates out friable material such as rock and glass by crushing and screening operations to generate a high metal content product.

A method for recovering metals from waste in which material is screened to leave a nonfibrous feedstock, the nonfeedstock is comminuted with a mill (e.g., a ball mill or rod) to liberate, flatten and separate the nonfibrous feedstock to obtain a mix of a metal fraction and residue, and the metal fraction and the residue are collected. There is a system employing the same to treat such materials.
