摘要： A process for delamination of a layered silicate in an aqueous medium includes treating a synthetic or naturally occurring 2:1 clay mineral layered silicate with a delamination agent, and contacting the treated layered silicate with an aqueous medium. An amount of the delamination agent used to treat the layered silicate can be at least equal to the cation exchange capacity of the layered silicate. A delaminated layered silicate can be obtained from the process and provided in a dispersion, a composite, or a barrier.

摘要： A composite medium for collecting mineral particles in an aqueous slurry has a polymer substrate deposited or penetrated with an inorganic material and further coated with a hydrophobic material. The hydrophobic material can be a hydrophobic silane or a hydrophobic polymer such as polysiloxane. Alternatively, the inorganic material deposited substrate is first reacted with a reactive silane and then coated with a hydrophobic polymer. The polymer substrate can be in the form of a spherical bead, a small cube, a filter or a conveyor.

摘要： An apparatus for removing mineral particles from loaded engineered collection media includes one or more solvents with sufficiently low surface tension. The engineered collection media are made of a synthetic material and have a surface coated with a hydrophobic material to provide a chemical bond between the mineral particles and the surface. The solvents together with a releasing mechanism are arranged to disrupt the chemical bond. Preferably, a surfactant or a nonionic surfactant is also added to the solvents.
