摘要

Extraction of potassium salt from a cement bypass product in an industrial plant, comprises providing the cement bypass product after delivering into a raw material warehouse for the process, separating the cement bypass product in the raw material warehouse, and formulating from many streams for the process by a homogeneous control of salt content to oxide content. Independent claims are also included for: (1) extraction of three different salts, preferably potassium salt, preferably potassium sulfate as the final product in an industrial plant, comprising using a cement bypass dust in forced-compacted form as an output product, preferably in the form of briquettes or using a cement bypass product as an output product; (2) producing cement, comprising removing cement bypass dust and carrying out forced compaction, preferably into briquettes; (3) extraction of potassium salt and cement-oxide from a cement bypass product in an industrial plant, comprising drying the extracted cement-oxide, such that it can be transported in a combined transport with the same transportation means to a cement plant, with which the cement bypass product was transported earlier to the industrial plant, or providing the cement bypass product initially in the industrial plant in the raw material warehouse, distributing into many process lines, enriching with process water, subsequently separating from the cement oxide and brine, and supplying the brine to a crystallization step for obtaining the potassium salt, where the process lines are combined before the crystallization step in a brine collector, so that process lines can be extended before the brine collector standard module, or enriching the cement bypass product with process water, subsequently separating from cement oxide and brine, where the resultant brine is decalcified before salt extraction step; and (4) a plant, preferably a cement plant or a processing plant for the extraction of potassium salt and cement oxide from a cement bypass product, which is designed to perform at least one of the above mentioned methods.
