State equation of mineral sands (pdf) | Paperity

The isothermal constants obtained by interpretation of triaxial sand tests at so called "critical state of sand" are clearly related to the universal ideal gas properties and molar properties of mineral sands. The corresponding constants for sand and gases or other volatile liquids have the same order of magnitude.

Core and mold sands; Facing sands; Replacements for specialty sands (e.g., chromite, olivine, or zircon in many applications) When used as a core and mold or facing sand, AlZiPure™ foundry sands provide improved surface finish compared with silica sand molds with less burn- in, erosion, and penetration on the surface of the casting.

Revised estimates of dose from ores and mineral sands

Recently, ICRP has published a new model of the respiratory tract and also new physiologically based biokinetic models for some elements which have naturally occurring radioactive isotopes. This paper gives a brief account of the ores and sands involved and explores the implications for dose coefficients of the new ICRP models.

Thermal Conductivity of selected Materials and Gases

Thermal conductivity is a material property that describes ability to conduct heat.Thermal conductivity can be defined as "the quantity of heat transmitted through a unit thickness of a material - in a direction normal to a surface of unit area - due to a unit temperature gradient under steady state conditions"

Heavy mineral sands ore deposits - Wikipedia

Heavy mineral sands are a class of ore deposit which is an important source of zirconium, titanium, thorium, tungsten, rare-earth elements, the industrial minerals diamond, sapphire, garnet, and occasionally precious metals or gemstones.. Heavy mineral sands are placer deposits formed most usually in beach environments by concentration due to the specific gravity of the mineral grains.

Soil gradation - Wikipedia

Soil gradation is a classification of a coarse-grained soil that ranks the soil based on the different particle sizes contained in the soil. Soil gradation is an important aspect of soil mechanics and geotechnical engineering because it is an indicator of other engineering properties such as compressibility, shear strength, and hydraulic conductivity. In a design, the gradation of the in situ ...

3 Melt Inclusions in Zircon - ia Tech

2002, Thomas et al. 2002). Melt inclusions in zircons of igneous origin are common, and have been identified in a wide range of igneous rock types, including quartz diorite and rhyolite, and in detri-tal zircon grains from heavy mineral sands (Fig. 1). The same properties that make zircon an excellent geochronometer also make zircon an ideal

It is indicated that the radon emanation coefficient (222 Rn EC) from 226 Ra in the various materials ranged between 0.5% in natural gypsum and about 18% in cement samples. The heavy mineral sands of high activity levels have low Rn emanation coefficients, while variable Rn EC was obtained for the materials containing low activity levels.
