It is made from crushed limestone that is sometimes deployed in pellet form. The pellets allow it to be spread evenly with minimal dust, yet they break down into a finely pulverized texture when it is activated with water. Once activated, Ag Lime dissolves and releases a base into a soil, thereby lowering its acidity.

Effect Of Fluxing Agents On Reduction Degradation

During induration at a high temperature, a considerable amount of slag/melt phase forms inside the iron ore pellets, comprising SiO2, Al2O3, CaO, MgO and FeO. After cooling, the slag phase solidifies and acts as an important bonding phase in the finished pellets and influences their room temperature as well as high temperature properties, especially reduction degradation.It was not a profitable source of iron until after World War II, and in the 1950s a process was devised that made it more commercially viable. In this process, the taconite is pulverized and the magnetite is separated by magnets. This iron powder is then combined with clay and limestone to form pellets containing 65% iron.
