Abstract
This invention provides a process for the production of dry free-flowing potassium carbonate sesquihydrate. The process involves the controlled hydration of high purity anhydrous potassium carbonate. The product of the process has at least about 90 percent particle size distribution in the range between about 200-1500 microns. The invention potassium carbonate sesquihydrate has properties which adapt the product for utility as a macromineral nutrient in animal feedstocks.
