A system and method for the calcination of minerals. The system comprises a vertically disposed reactor segment configured to impart horizontal forces on particles passing through the reactor segment in a vertical direction; an injector unit for receiving granular feedstock, the injector unit being disposed at a top portion of the reactor segment, whereby granules of the feedstock move through the reactor segment in a granular flow under at least one of a group consisting of a force of steam, gravitational force and a centrifugal force; a reactor heat exchange unit thermally coupled to a wall of the reactor segment for providing heat to the flowing granules inside the reactor segment through heat transfer through the wall of the reactor segment; one or more inlets formed in the reactor segment for introducing a superheated gas into the reactor segment to create conditions of a gas-solid multiphase system; and one or more exhaust openings formed in the retort segment such that gas products are at least partially flushed from the reactor segment under the flow of the superheated gas from the inlets to the exhaust openings.

1. A system for the calcination of minerals, the system comprising: a vertically disposed reactor segment configured to impart horizontal forces on particles passing through the reactor chamber in a vertical direction;an injector unit for receiving granular feedstock, the injector unit being disposed at a top portion of the reactor segment, whereby granules of the feedstock move through the reactor segment in a granular flow under at least one of a group consisting of a force of steam, gravitational force and a centrifugal force;a reactor heat exchange unit thermally coupled to a wall of the reactor segment for providing heat to the flowing granules inside the reactor segment through heat transfer through the wall of the reactor chamber;one or more inlets formed in the reactor segment for introducing a superheated steam into the reactor segment to create conditions of a gas-solid multiphase system; andone or more exhaust openings formed in the reactor segment such that gas products of the calcination are at least partially flushed from the reactor segment under the flow of the superheated steam from the inlets to the exhaust openings as a mixture of the superheated steam and gas products. 2. The system as claimed in claim 1, wherein the reactor segment comprises one or more reactor chambers, and one or more gas granule separator coupled to the reactor chambers that utilises a vortex formed from the passage of material through the reactor chamber to separate the gas products from the granules. 3. The system as claimed in claim 2, further comprising two or more reactor chambers and respective coupled gas-granule separators connected in series, such that processed material from one reactor chamber collected utilizing the gas-granule separator coupled to said one reactor chamber are fed into another reactor chamber and collected, after further processing in said other reactor chamber, utilizing the gas-granule separator coupled to said other reactor chamber. 4. The system as claimed in claim 3, wherein at least one of the gas-particle separator comprises a heater unit for heating the material collected for providing a trimming reactor functionality. 5. The system as claimed in claim 4, wherein at least the gas-particle separator coupled to said one reactor chamber further comprises a pumping unit for pumping the material collected during said heating for suppressing a back reaction. 6. The system as claimed in claim 1, wherein the reactor segment comprises a plurality of reactor chambers coupled to one particle separator. 7. The system as claimed in claim 1, wherein the reactor heat exchange unit utilizes flameless distributed heating, and at least one of the exhaust openings is coupled to the reactor heat exchange unit for directing a portion of the gas products into fuel for the flameless distributed heating for facilitating suppression of pyrolysis. 8. The system as claimed in claim 1, wherein the reactor segment comprises one or more linear tubes as reactor chambers and one or more gas particle separators, the gas separators imparting the horizontal forces on the particles. 9. The system as claimed in claim 1, wherein the reactor segment comprises one or more spiral tubes respectively formed into a helix as reactor chambers. 10. The system as claimed in claim 9, wherein the exhaust openings comprises a central column formed within an inner circumference of the spiral tube, whereby the system exhibits a counter-flow of the gas products with respect to the granules in the spiral tube. 11. The system as claimed in claim 10, further comprising a conveyer tube coupled to the injector and disposed inside the central column, for conveying the granules from a base of the reactor segment to the injector. 12. The system as claimed in claim 11, wherein the granules are conveyed through the conveyer tube under the force of the superheated steam, whereby the injector functions as the or one of the inlets for introducing the superheated steam into the spiral tube. 13. The system as claimed in claim 11, wherein the reactor heat exchange unit comprises a flameless distributed heating unit, and one or more of a group consisting of the reactor chamber, the gas granule separator, the central column and the conveyer tube are cast in the porous flameless distributed heating unit. 14. The system as claimed in claim 1, wherein a residence time of the granules in the reactor segment is less than 10 seconds. 15. The system as claimed in claim 1, wherein the granules have a size distribution between 40 microns to 250 microns. 16. The system as claimed in claim 1, wherein the reactor heat exchange unit utilizes combustion, and wherein the wall of the reaction chamber prevents transfer of combustion of gases to the reaction chamber.
