Abstract
The choice of the Karatau phosphorites (The Republic of Kazakhstan) as a perspective phosphorus-containing raw material for Belarusian producers is substantiated. The process of activation of phosphate of the Zhanatas deposit (Karatau basin (Kazakhstan)) in a drum ball mill, a dismembrator and a vibratory mill was researched. The influence of solid potassium- and nitrogen-containing components (potassium chloride, ammonium sulfate, urea) on the activability of the phosphorites has been studied. Under optimum conditions more than 60 % of P2 O5 of phosphorite can be transferred to the digestible form by the “dry” method, which is a prerequisite for the development of a non-waste and environmentally safe technology for the production of NPK fertilizers.
