摘要:
A method of sorting mined material, such as mined ore, is disclosed. The method comprises exposing particles of mined material to radio frequency electromagnetic radiation and heating particles depending on the minerals present in the particles and then thermally analyzing particles exposed to radio frequency electromagnetic radiation to detect temperature differences between particles which indicate differences in the minerals in the particles. The method also comprises sorting the particles on the basis of the results of the thermal analysis.
摘要:
Ways of applying microwaves to feedstock to be processed are disclosed. One embodiment relates to heating inter-layer water in vermiculite to expand the vermiculite. Another embodiment relates to heating water in oil-contaminated materials and waste products, such as drilling cuttings, contaminated soils and certain types of animal by-products, to drive out oil. In some embodiments a microwave tunnel applicator has the microwaves applied from beneath the feedstock.
摘要:
An apparatus for processing mined material that includes an applicator assembly (2) is disclosed. The applicator assembly includes a plurality of applicators (12) for exposing a moving bed of fragments of mined material to electromagnetic radiation as the bed of fragments moves through the applicator assembly. The applicators are arranged so that, in use, there is a high level of assurance that all of the fragments in the moving bed will receive at least a minimum exposure to electromagnetic radiation by the time the fragments reach an outlet end (8) of the applicator assembly.

摘要:
An apparatus for processing mined material, such as mined ore, is disclosed. The apparatus includes an applicator (2) for exposing a downwardly moving bed of fragments of a material to electromagnetic radiation. The applicator includes a tube (4) for containing the moving bed of fragments that has an upper inlet and a lower outlet and a transverse cross-sectional area that increases between the inlet and the outlet.
摘要:
An apparatus for sorting mined material, such as mined ore, includes an applicator for exposing fragments of a material to electromagnetic radiation and an assembly for distributing fragments from the applicator so that the fragments move downwardly and outwardly from an upper inlet of the assembly and are discharged from a lower outlet of the assembly as individual, separate fragments that are not in contact with each other. The apparatus also includes a detection and assessment system for detecting and assessing one or more than one characteristic of the fragments and a sorting means in the form of a separator for separating the fragments into multiple streams in response to the assessment.
