Annotation
The article presents the physical and mechanical characteristics and chemical composition of the initial raw materials - glauconite sand and nodular phosphorites of the Krantau, Khojakul, Beshtyu be and Sultan-Uizdag deposits. The methods of determining the chemical composition and commercial quality, as well as conducting physico-chemical studies of raw materials – glauconite sand and nodular phosphorites of Karakalpakstan and finished products using modern research instruments (X-ray, electron microscopic, thermal, optical emission spectrometer with inductively coupled argon plasma - ECO with ISP, HPLC-mass-spectrometry, ESI mass spectrometry studies, elemental analysis).
