A transportable apparatus for separating and recovering fine particles from a slurry or a mixture comprising the fine particles and other particles; the apparatus comprising one or more fines separators and/or one or more fines classifiers, said separators and classifiers being mounted on a transportable frame for separating fine particles from the slurry, wherein the apparatus is operable for receiving the slurry from a discharge stream of an ore processing plant and/or the mixture being recovered from a tailings dam.

A process for cleaning and dewatering hydrophobic particulate materials is presented. The process is performed in in two steps: 1) agglomeration of the hydrophobic particles in a first hydrophobic liquid/aqueous mixture; followed by 2) dispersion of the agglomerates in a second hydrophobic liquid to release the water trapped within the agglomerates along with the entrained hydrophilic particles.

Provided is a method for upgrading a coal slime through synergistic dehydration, including: subjecting coal slime water to be treated to filter pressing dehydration to obtain a filter cake; and crushing the filter cake, sieving and sizing, and subjecting a resulting oversize to steam transient dehydration to obtain a dehydrated coal slime.

Upgraded coal, method of forming the same, and graphene films and quantum dots made therefrom. A method of upgrading coal includes cleaning coal to form a cleaned coal residue. The method also includes (A) reacting the cleaned coal residue with an oxidizable inorganic metallic agent, or (B) reacting the cleaned coal residue with a reducing agent, or a combination thereof, to form the upgraded coal.

A process for concentrating and separating rare earth elements including lithium and titanium from coal refuse. Crushed refuse admixed with water is transferred to a first cyclone separator to divide the admixture into a refuse rich slurry stream and a carbonaceous rich slurry stream. The refuse rich slurry stream is dewatered through a vibrating screen and the water sent to a raw feed sump source. The carbonaceous rich slurry is directed to a second cyclone separator to separate low quality carbon from high quality carbon, the high quality carbon is transferred to a third cyclone separator used to separate the element rich media. The media water is returned to the raw feed sump and the bleed media is directed to a centrifuge which thickens the concentration of rare earth elements and minerals. The effluent is directed to a tailings pond or vacuum press.
