Studi Komposisi Mineral Tepung Batu Bukit Kamang Sebagai Bahan Baku Pakan Sumber Mineral

Abstract

The study was conducted to determine mineral content of limestone originated from natural deposit of Bukit Kamang for feedstuff. Six samples were prepared and chemically analyzed. The first was limestone in meal form as a product of local milling industry. Another five samples were deposit components with different color of blackish, dark blue, blue, light blue and white. There was 21 kinds of mineral determined which were divided into 3 groups: macros (Ca, P, Mg, Na, K, Cl and S), trace minerals (Mn, Zn, Fe, Cu, Se, Co and Mo) and toxic elements (As, F, Hg, Cd, Pb, Ni and Cr). The results showed that Bukit Kamang’s limestone contained considerable high essential minerals of Ca, Se, Fe and Mn. The limestone consisted of 38%-40% Ca, 388 ppm Se, 295 ppm Fe and 205 ppm Mn. There were two toxic elements detected: Pb and Cd, but their concentration was found relatively low: 28 and 7 ppm, respectively.
