| titleOfInvention | Synnyrite processing method |
| abstract | The invention relates to the field of non-ferrous metallurgy and can be used in the production of alumina alum from synonyrite. The purpose of the invention is to simplify and reduce the cost of the process. For this, the mixture consisting of synonyrite and limestone at a molar ratio of Kalishpatovy part of synonyth to calcium carbonate 1: 4 is sintered at 1250-1 ° C C for 4 hours. Sinter is treated with 40-60% sulfuric acid at grin hot water and separate the solution from the insoluble residue for 30 minutes. Alum is crystallized from the solution. The method allows to simplify the process by replacing the two-stage sulfuric acid treatment with a single-stage process and eliminating the potash regeneration operation, as well as reducing the cost of processing 1 ton of synrynite. 3 hp ff.
