METHOD AND DEVICE FOR IMPLEMENTING TRANSFERS OF MATERIAL OF PHYSICAL AND / OR CHEMICAL REACTIONS OR OF THERMAL TRANSFERS IN A FLUID MEDIUM

摘要

The subject of the invention is a process intended in particular for carrying out physical and / or chemical reactions, as well as installations and devices for carrying out this process. /P P According to the invention, a magnetic material dispersed in the fluid is subjected to the action of a variable magnetic field. It is thus possible to ensure effective agitation of this fluid and to favor reactions involving, on the one hand, a constituent of the fluid medium, on the other hand, particles dispersed in this fluid, a substance at least partially active at the surface. It can be, in particular, a ferromagnetic solid substance and a compound in solution in the fluid and not magnetic. /P P The invention applies inter alia to various treatments of magnetic ores.
