INVESTIGATION OF THE DECOMPOSITION OF PHOSPHATE RAW MATERIALS IN THE PRESENCE OF PEAT USING PHOSPHORIC ACID
In the process of decomposition of phosphate raw materials, the dynamics of transformation of its constituent mineral phosphoric components: fluorapatite and its derivatives into available for plants dihydro - and hydroorthophosphates of calcium and the influence of a natural organic activator on it are studied.. The composition of the obtained organomineral products was evaluated. The questions of intensification of processing of phosphorite in phosphate-peat systems with additional involvement of nitric acid are considered. The possibilities of reducing the amount of acidic reagents to 50% are shown, while guaranteeing a high degree of use of the target raw material component (94%) and the absence of waste.
