Introduction. The use of 3-dimensional (3D) scaffolds is an approach of bone tissue engineering for the reconstruction of massive bone defects such as diseased or damaged bones (Karp et al., 2003).Scaffolds should be biocompatible and provide a temporal and spatial three-dimensional framework to form the designed tissues; also, they should act as an artificial …

The mineral apatite has been used as a geochemical tool to estimate the volatile contents of lunar magmas, owing to its ability to incorporate all relevant volatiles as major (F-Cl-H) or trace elements (S-C). Recently, Konecke et al. [4-5] improved our understanding of sulfur incorporation into apatite as a function of redox conditions.

Calcium apatite is a mineral commonly used in fertilizer and is also a major component of bones and teeth. The researchers formed a "sponge" in the ground by injecting two inexpensive and nontoxic chemicals, calcium citrate and sodium phosphate, into a well especially designed for injecting solutions underground at the former uranium mill.

The apatite was ground in a rotary mill and wet screened at 150, 86, 75, 53, and 38 µm. The four narrow size fractions and the minus 38 µm apatite were used in this research. Each of the narrow size fractions of apatite were used to simulate the leaching of one uniform particle size. A chemical analysis of the apatite sample is shown in table 1.

Radiation Facts. Regardless of how uranium is removed from rock, the extraction process creates radioactive wastes. If not managed properly, mining waste and mill tailings can contaminate the environment. Uranium is a naturally-occurring radioactive element that has been mined and used for its chemical properties for more than a thousand years.
