The present disclosure relates to a method for producing metallurgical coke from non-coking coal. The method comprising, densifying, the non-coking coal to form pellets. The densified pellets will be placed in a microwave oven within plurality of bricks and are subjected for pyrolysis. For carrying our pyrolysis, the pellets are carried out by heating, the pellets in the microwave oven at a predetermined temperature under an inert atmosphere at atmospheric pressure, and then the pellets are cooled in the microwave oven under the inert atmosphere. This process coverts non-coking coal to the metallurgical coke in a quicker time, and without use of any susceptors.

Method for producing metallurgical coke from non-coking coal

A heap of a material to be leached to recover a valuable metal from the material includes an electromagnetic heating system to generate heat in situ in the heap.

The present disclosure provides an apparatus for treatment of mined material. The apparatus comprises a source for generating electromagnetic radiation and a microwave inlet region for exposing fragments of the mined material to the electromagnetic radiation. Further, the apparatus comprises a reflective structure adjacent the microwave inlet region and providing, or surrounding, a passage for guiding the fragments of the mined material to the microwave inlet region. The reflective structure is arranged to attenuate penetration of the electromagnetic radiation from the microwave inlet region into the passage during throughput of the fragments of the mined material.

Apparatus and a method for treatment of mined material with electromagnetic radiation

A microwave radiation applicator for exposing mined material to microwave radiation is disclosed. The applicator includes side wallsand end wallsthat define a chamber. One end wall has an opening that forms an inlet for mined material to be supplied to the chamber and the other end wall has an opening that defines an outlet for mined material to be discharged from the chamber. The side walls define a pentagon in transverse cross-section.

Vessel for the microwave treatment of ore

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.

Sorting mined material

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.
