Calcination is intended to improve the mineral concentration and physical characteristics of limestones and oyster shells which vary based on different chemical compositions, textures, and impurities of their types and habitats. The present research aimed to study the effects of calcination on mineral composition and the physical properties of limestones and oyster derived from various sources. Limestone samples from three local limestone mining and oyster shell samples from three shellfish species were calcined by burning at a temperature of 800-1000°C. The calcined products were analyzed for mineral content (Ca, P, Mg, Cu, Zn, and Mn), physical properties (bulk density, tapped density, specific density, and angle of repose), and particle size. Results indicated that calcination had no significant effect on Ca and P concentrations but reduced micro mineral concentration. Limestones had a higher Mg concentration than that of oyster shells, and calcination increased Mg concentration. Calcined oyster shells had higher densities, percentages of fine particles, and lower angles of response. The results suggested that the type of limestones and oyster shells could determine their thermal decomposition properties. date: 2021-12-25 publication: World's Veterinary Journal volume: 11 number: 4 publisher: Scienceline Publication, Ltd pagerange: 578-586 id_number: https://dx.doi.org/10.54203/scil.2021.wvj73 refereed: TRUE issn: 23224568 (ISSN) official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85123243929&doi=10.54203%2fscil.2021.wvj73&partnerID=40&md5=8eea0beeb3280a4c76baab01f04f441d j_index: scopus citation: (2021) The Effects of Calcination on Mineral Composition and Physical Properties of Limestones and Oyster Shells Derived from Different Sources.
