What's the difference between mineral and olivine?

Mineral


Definition:

  • (v. i.) An inorganic species or substance occurring in nature, having a definite chemical composition and usually a distinct crystalline form. Rocks, except certain glassy igneous forms, are either simple minerals or aggregates of minerals.
  • (v. i.) A mine.
  • (v. i.) Anything which is neither animal nor vegetable, as in the most general classification of things into three kingdoms (animal, vegetable, and mineral).
  • (a.) Of or pertaining to minerals; consisting of a mineral or of minerals; as, a mineral substance.
  • (a.) Impregnated with minerals; as, mineral waters.

  • (17) Unsupplemented human breast milk may not provide sufficient calcium and phosphorus for the rapidly growing preterm infant to match the accumulation that should have taken place in utero and to permit normal bone mineralization.

  • (20) These diets were: diet C consisting of commercial Rat Chow: diet CG, the same diet diluted with 70% glucose calories, diet A, a simulated "American" diet made up of 25 widely used foods, diet AS, the same diet supplemented with small amounts of 25 vitamins and minerals.

Olivine


Definition:

  • (n.) A common name of the yellowish green mineral chrysolite, esp. the variety found in eruptive rocks.

Example Sentences:

  • (1) The study demonstrates that the partial substitution of olivine can reduce the concentration of free silica to acceptable health levels.
  • (2) Olivine inhalation also suppressed splenic PFCs and alveolar macrophage phagocytosis, but to a lesser degree than silica.
  • (3) Two factories were singled out for specific attention: one where asbestos was used in calcium silicate brick production and one where olivine, used as a raw material, may have been contaminated with natural mineral fibers and where the production process would have exposed workers to coal-tar pitch volatiles.
  • (4) Olivine is a magnesium iron silicate (Mg, Fe) SiO4 which occurs in nature and contains little or no free silica.

  • (8) In animals tested after 570 days of dust exposure, it was determined that the ability to lyse allogeneic tumor cells in vitro was impaired by olivine slightly more than by silica, while antibody-dependent cell-mediated cytotoxic and mitogenic responses by splenic lymphocytes were unchanged by inhalation of either dust.
  • (9) Field tests were carried out to compare the air quailty in a gray iron foundry before and after changing the molding material from the standard silica based sand to the mineral olivine.
  • (10) Previous studies have shown that silica exposures in the cleaning of castings can be reduced or eliminated through the use of mold coatings, which minimize sand burn-in on the casting surface; by application of high-velocity, low-volume exhaust hoods; and by the use of a nonsilica molding aggregate such as olivine.
