This paper explores the utilisation of calcite waste, which is already in existence as common waste by-product, as a calcium source in the synthesis of hydroxyapatite (HAP). Calcium carbonate was extracted from waste calcite in acidic media and directly employed in the standard wet precipitation protocol to obtain stoichiometric HAP.

Calcite belongs to the calcite group of minerals, a group of related carbonates that are isomorphous with one another. They are similar in many physical properties, and may partially or fully replace one another, forming a solid solution series.All members of the calcite group crystallize in the trigonal system, have perfect rhombohedral cleavage, and exhibit strong double refraction in ...

Production of precipitated calcium carbonate (PCC) via carbon dioxide (CO 2) pressure-swing mineral carbonation is a potential way to utilise calcium-rich steel slag and carbon dioxide.Calcium supersaturation and slag surface passivation are two aspects of the calcium extraction step that strongly influence the choice of operating conditions necessary for rapid and complete calcium leaching ...

Apr 12, 2019· Septarian is one of the most beautiful and interesting stones that you will see. That’s because no two stones look exactly the same! The name septarian is from the Latin word ‘septum’, which means seven, or ‘saeptum’, meaning a wall or an enclosure.The stone also got its name because it seems to form in a pattern of seven.

Unit Cells: A Three-Dimensional Graph . The lattice points in a cubic unit cell can be described in terms of a three-dimensional graph. Because all three cell-edge lengths are the same in a cubic unit cell, it doesn't matter what orientation is used for the a, b, and c axes. For the sake of argument, we'll define the a axis as the vertical axis of our coordinate system, as shown in the figure ...

Calcite is a "ubiquitous" mineral. Ubiquitous means "found everywhere." Calcite occurs in igneous, metamorphic, and sedimentary rocks and is the most commonly encountered carbonate mineral. If you place one drop of cold hydrochloric acid on calcite, the entire drop of acid will erupt with bubbles and a vigorous fizz will last for a few seconds.

calcite (kăl`sīt), very widely distributed mineral, commonly white or colorless, but appearing in a great variety of colors owing to impurities.Chemically it is calcium carbonate, CaCO 3, but it frequently contains manganese, iron, or magnesium in place of the calcium.It crystallizes in the hexagonal system, its crystals being characterized by highly perfect cleavage.
