Disintegration mineral processing

Radium is continuously disintegrating the process is subatomic and can neither be accelerated nor retarded by any means at our disposal. Radium is a member of the Uranium series and may be found in all minerals containing this latter element. The scheme in Fig. 8 shows the various stages of the disintegration of uranium,... 

Biological weathering involves the disintegration of rock and its minerals by the chemical and physical actions of living organisms, for example plant roots or bacteria, which can dissolve minerals by oxidation or reduction processes [11]. 

Atomized aluminum powder is milled in ball mills in the presence of mineral spirit and a lubricant. After the disintegration process, the pigment slurry is sieved and classified and pressed on a filter press to remove the excess solvent. The press cake (typical solvent content ca. 75 to 80%) is then blended with organic solvents to form an aluminum paste typically containing 65% solids and 35% solvent. 

Tribasic calcium phosphate is widely used as a capsule diluent and tablet filler/binder in either direct-compression or wet-granulation processes. The primary bonding mechanism in compaction is plastic deformation. As with dibasic calcium phosphate, a lubricant and a disintegrant should usually be incorporated in capsule or tablet formulations that include tribasic calcium phosphate. In some cases tribasic calcium phosphate has been used as a disintegrant. It is most widely used in vitamin and mineral preparations as a filler and as a binder. It is a source of both calcium and phosphorus, the two main osteogenic minerals for bone health. The bioavailability of the calcium is well known to be improved by the presence of cholecalciferol. Recent research reports that combinations of tribasic calcium phosphate and vitamin D3 are a cost-effective advance in bone fracture prevention. ... 

With a few notable exceptions such as gold and platinum, metals do not occur in earth s crust in their elemental states. They are present instead as one of two or more elements combined into inorganic crystalline compounds called minerals. To recover the metals from their entrapping compounds, it is natural to choose the least expensive options we mine and process only those minerals from which the desired metals can be easily obtained. In practice, this means that we choose those minerals that require the least expenditure of energy in order to effect the chemical disintegration and release of the metal. 

High biotic activity is characteristic for soils of Meadow Steppe ecosystems with relatively high precipitation. An enormous number of invertebrates promptly disintegrate and digest the plant residues and mix them with the mineral soil matter. The presence of the predominant part of plant biomass as the underground material facilitates greatly this process.
