    The effects of quartz, Fe2O3 (hematite), CaCO3, & Na feldspar, on host defenses against bacterial pulmonary infection was investigated. Mice which received intratracheal instillations of 10, 33, and 100 mug/mouse were exposed within an hour to aerosols of viable streptococcus, & pneumonia-induced mortality was measured. At 33 and 100 mug/mouse, all particles significantly increased mortality. At

    Additionally, hematite has three main advantages over barite: (1) higher specific gravity; (2) better particle distribution; and (3) a low particle attrition rate. For use in the oil field, hematite is refined by removing the quartz to an amount which is less than 1%. The hematite API specific gravity specification is 4.9. Specific gravity is the key to mud weighting material performance. Less hematite is required to

  • Hematite: Mineral information, data and localities.

    Originally named about 300-325 BCE by Theophrastus from the Greek, "αιματίτις λίθος" ("aematitis lithos") for "blood stone". It is possibly the first mineral ever named ending with a "-ite" suffix. Translated in 79 by Pliny the Elder to haematites, "bloodlike", in allusion to the vivid red colour of the powder.

    Hematite has a specific gravity of >5.05, which is 19% greater than the density of Barite (4.1). Thus, for a given mud weight, a system weighted with Hematite will contain fewer solids by volume. A lower solids concentration will contribute to improved rheological properties, improved penetration rate and decreased overall mud costs

    The density increase is normally developed by adding a very dense material like barite (specific gravity of 4.2) or hematite (specific gravity of 5.02). To create the low-shear-rate viscosities (LSRV), various additives are blended into the liquid phase. In a water-based drilling fluid, LSRV can be developed by using clay (bentonite), a clay-extender (partially hydrolyzed polyacrylamide), or a

    Hematite, also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3).With this it forms a complete solid solution at temperatures above
