2020/09/01Therefore, a proper selection of the comminution machine for a certain mineral system leads to a specified product with the least energy consumption. In general, the selection of comminution machines is based on the feed material characterization [5], final product specification [6], available operational system [7], and energy efficiency of the machines [8] .
Apatite
Apatite is a group of phosphate minerals, usually referring to hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH−, F− and Cl− ions, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca10(PO4)6(OH,F,Cl)2, and the crystal unit cell formulae of the

In summary, the type of mineral in the stone was predictive of positive stone culture, but this correlation is imperfect, as over half of non-struvite, non-apatite stones were found to harbor culturable organisms. We conclude that
Apatite Stone – Meaning, Benefits and Properties
Also used as a talisman for the treatment of some health problems, yellow apatite is especially indicated to benefit the spleen, liver and gallbladder. There are many healing properties attributed to this beautiful apatite mineral: It is closely related to the larynx and heart chakra.

However, both thermal treatment and hydrothermal hydrolysis could produce biological apatite for clinical application and reduce the risk of disease infection at the same time. Besides, chemical treatment could work as a supplementary method to other approaches, while supercritical CO 2 fluid extraction may be adopted for the framework preparation in bone engineering by

The Lunar Apatite Paradox
2014/04/25The long-running story of the dry Moon was rewritten a few years ago when hydrogen-bearing glass spherules were discovered. The highest water contents are found in lunar apatite, at levels suspiciously comparable to the water content of Earth apatites. Boyce et al. (p. [400][1], published online 20 March; see the Perspective by [Anand][2] ) now show that the water content of lunar apatite

Another specificity of biological apatites, which was more recently established, is the presence of hydrogen phosphate (HPO 4 2−) ions in PO 4 3− sites [21,22,23].These two types of bivalent ions substituting for PO 4 3− (type B CO 3 2− and HPO 4 2−) have been shown to correspond to the formation of calcium deficient apatites, the chemical formulas of which have been the subject

The Identification and Synthesis of Lead Apatite Minerals
Recently, a new geological lead apatite mineral called phosphohedyphane Ca 2 Pb 3 (PO 4) 3 Cl has been identified and its crystallography determined []. The lead apatites belong to a large group of minerals having the apatite crystal structure (space group P 6 3 / m ).

Minerals
An important component of phosphorite (phosphate rock) is carbonate apatite, as it is required for phosphorous fertilizer production due to its increased phosphate solubility caused by carbonate substitution in the apatite mineral lattice. High phosphate concentrations in municipal wastewater treatment plants are commonly reduced by precipitating iron phosphate by addition of iron

Cleaning mineral specimens: a guide for mineral collectors and
Once clean, the mineral should be rinsed under running water, and is best soak in frequently changed water for an equal amount of time that soaked in the SIO. Conclusion I stayed clear of the more hazardous hydrofluoric, sulfuric, nitric acids and treatments for specialized uses such as cleaning native copper.
Synthetic Phase with the Structure of Apatite
2016/01/08Synthetic cesanite as an analogue of mineral with the composition Na 3 Ca 2 (SO 4) 3 (OH) (Section 2.1.7) shows typical features of the apatite structure, as shown in Fig. 34. The symmetry reduction from the centrosymmetric space group P6 3 /m to the non-centrosymmetric space group P 6 leads to a doubling of the number of crystallographically independent sites.

Mineral
A rock is an aggregate of one or more minerals or mineraloids. Some rocks, such as limestone or quartzite, are composed primarily of one mineral – calcite or aragonite in the case of limestone, and quartz in the latter case. Other rocks can be defined by relative abundances of key (essential) minerals; a
Phosphate Minerals
J.P. Attfield, in Encyclopedia of Materials: Science and Technology, 20014.9 Minerals Several hundred phosphate minerals are known, virtually all of which are orthophosphates. The important mineral apatite, ideally Ca 5 (PO 4) 3 X (X=F, Cl, OH), is found in igneous pegmatite rocks and hydrothermal veins.
Introduction to Apatites
2014/11/11Apatite is the generic name, which was first introduced by German geologist A.G. Werner. These minerals and their synthetic analogs represent a major class of ionic compounds and the most common crystalline form of calcium phosphates, which are of interest of many industrial branches and scientific disciplines. Since, apatite (fluorapatite) is the most abundant phosphate mineral, apatite
The Identification and Synthesis of Lead Apatite Minerals
Abstract Phosphate is added to drinking water in the UK to minimise the release of lead from lead water pipes. The phosphate encourages the formation of insoluble lead apatites on the walls of the pipe. Hydroxylpyromorphite Pb 5 (PO 4) 3 OH is the lead apatite that is most often used to model lead levels in tap water; however, its presence has not been confirmed.
