摘要： A process for separating heavy metals from a phosphoric starting material includes, in a step (i), heating the starting material to a temperature between 700 and 1,100° C. in a first reactor and withdrawing combustion gas. In a step (ii), the heated starting material at the temperature between 700 and 1,100° C. is transferred to a second reactor, chlorides of alkaline and earth alkaline metals are added and process gas is withdrawn.

摘要： A method for the heat treatment of granular solids includes initially introducing solids into a first reactor configured as a flash reactor or fluidized bed reactor where they are brought into contact with hot gases at temperatures in the range 500° C. to 1500° C. Next, the solids are passed through a residence time reactor in which they are fluidized. The residence time reactor is configured in a manner such that it has various regions which are separated from one another, from which the solid can be withdrawn in a manner such that it is provided with a variety of residence times in the residence time reactor.
