The disclosed technology includes a method for producing ultrafine alumina from salt slag waste generated in aluminum recycling useful in the manufacture of durable ceramic products; a system for recovering alumina from salt slag waste; a method and systems for recovering salts, aluminum and alumina from salt slag waste; and a method and systems of capturing ammonia in a process recovering salts, aluminum and alumina from salt slag waste. The methods and systems provided crush the dry particles of the salt slag waste, scrub the slag with water, and with steam and by means of a vented alumina press, dewater the scrubbed slag particles. In some methods and systems of the disclosed technology, the particles of the pressed alumina cake are further reduced. In some methods and systems, the salt in the salt effluent is crystalized. In some methods and systems of the disclosed technology, the ammonia is contained and captured.

A method of processing organics having a relocatable trailer transporting a hopper, an infeed conveyor, an organics separation unit, an organics conveyor, an inorganics waste conveyor, and a control panel between processing locations of organic material. The control panel regulates the operation of the infeed conveyor, the organics separation unit, the organics conveyor and the inorganics waste conveyor. Following completion of processing the components carried on the trailer may be cleaned and the trailer supporting the processing components may be moved to another processing location.

An apparatus for destroying data storage devices comprises a shredder assembly, a hammer mill assembly, a chute mounted in an open communication with an interior of the shredder assembly and with an interior of the hammer mill assembly, the chute sized and shaped to transfer shredded remnants from the shredder assembly into the hammer mill assembly, a power drive assembly coupled to each of the shredder assembly and the hammer mill assembly, and a control assembly configured to operate the shredder assembly and the hammer mill assembly.

A system for eliminating unexploded ordnance from a mixture. The system includes a separation plant, including a crusher, a magnetic separation station, and a screen plant. The crusher reduces the size of pieces in the mixture, the magnetic separator separates pieces containing a significant amount of ferrous metal, and the screen separates small pieces from larger pieces. The fine output of the screen is composed of pieces that are sufficiently small to pose little hazard; they may be further subjected to heat treatment. Large pieces containing ferrous metal, or large pieces containing nonferrous metal, may be explosive and are transported, using an unmanned machine, to an inspection plant where they are sorted and where any unexploded ordnance is identified and disposed of. The separation plant is sufficiently distant from the inspection plant that an explosion at the separation plant does not pose a hazard to personnel at the inspection plant.

The present application pertains to a process for the decomposition of biomass-material.

This invention relates to a process for recovering value metals from sulphide ore, including steps of crushing ore in a primary crusher (14) to a size of about 40 cm and less, passing the crushed ore through one or more of the following pre-beneficiation processes such as bulk sorting (16) and screening (20) followed by coarse floatation (46/50), or gravity separation or magnetic separation. A waste stream (54) from the pre-beneficiation process/es with a particle size greater than 100 μm is stacked in a heap (26) and subjected to a heap leach. This integrated process utilises the pre-beneficiation techniques best suited to the characteristics of a particular orebody; and during the pre-beneficiation simultaneously creating a low grade stream that yields significantly higher recoveries than achievable by normal heap leaching of low grade run of mine ore.
