Calcium (Ca) is a metallic element characterized by low electronegativity and high reactivity. It rarely occurs in its pure form in nature and is usually found combined with oxygen and other elements. The inorganic monoatomic Ca cation is referred to as Ca²⁺. Although calcium is an essential component of human teeth and bones, an excess amount of Ca can negatively affect the health of humans and animals. The abundance of industrial wastes containing Ca²⁺ poses environmental challenges that influence the health of humans, animals, and plants, and is closely associated with natural geological sources and the expansion of industrialization.
In this article, the commercial properties of lime–ammonium nitrate (LAN) obtained by adding waste from the Almalyk Mining and Metallurgical Complex (AMMC) Lime Plant (limestone waste – LW) to chemically pure molten ammonium nitrate were studied on a scientific basis. The research examined the granule strength, dissolution time of granular fertilizers, density and viscosity (rheological properties) of the melt under different time intervals and temperature conditions.
