The Study of Biogeoavailability of Calcium in Ashaka Cement Industry Environs of North Eastern Zone of Nigeria
The samples in the study of Ashaka cement environs were collected on both mineralized and unmineralized ground. These were analyzed to determine the amounts of the elements absorbed by the plants in the area under study using analytical methods (IR, AAS). The observations and prediction of the results show that secondary carbonate minerals, especially those of the common base metals such as magnesium, lead and zinc may be found in Gombe-Bauchi ore bodies include associate minerals. The associate minerals that may be found are hydrozincite, Zn5(CO3)2(OH)6, hydrocerussite, Pb3 (CO3)2 (OH)2 and the very rare mineral plumbonacrite, PbOO(OH)6(CO3)2, Dypingite, Mg5(CO3)4(OH)2.5H2O etc. This is in accordance with the statistical interpretation of the results. The standard deviation were identified as action line , which is equivalent to 59.16 and 49.84 , while two standard error as warning lines, that is resulting in 58.91 . The expectation of these minerals in abundance depends on the ratio of a(Ca2+)/a(Mg2+), a(Ca2+)/a(Zn2+) and a(Ca2+)/a(Pb2+). The technological importances of these associate and very rare minerals are discussed.
