What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or weathering.

Biasill™ sand is used as a low free silica abrasive for air sandblasting. Biasill™ cleans faster, safer, and more efficiently than silica sand. Biasill™ is most useful where mill scale and light rust are to be removed and in applications where a shallow profile is desired. Because it is a finer grade sand, Biasill™ also
Answer (1 of 2): While the density of silica is 2.65 g/cc, the average density of silica sand will be lower and depend on its origin. Rounded grains of approx. uniform diameter (eg sea sand) will have greater porosity, hence lower density than a 'sharp' sand with a wide range of particle sizes wh...
sintering temperature of chromite sand which contributed to an increase in the occurrence of casting defects. Keywords: Sintering temperature, turbidity, silica content, fine particles, South African chromite sand . INTRODUCTION Chromite sand has a chemical composition of FeCr 2 O 4 and a high specific gravity of 4.5 which is a very good heat ...
The specific gravity is 4.3-4.6, the hardness is 5.5-7 Mohr and thermal expansion at 0.005. Chromite sand has rather high thermal conductivity, the melting point at 1760-1980 °C Chromite sand comes from natural and by product of Ferro Chromium smelting, for the chrimite sand which come from natural it always found some iron (Fe) including then ...
Silica Sand undergoes an alpha-beta phase transformation at approx 350oC – 650oC. This corresponds to the temperature zone that the mould experiences during cooling. This can lead to expansion defects such as veining or cracking in castings where silica sand moulds are used Chromite has a much lower expansion over the same temperature range.
Gravity Separation is used to separate mineral and gangue with a large difference in their Specific Gravities. Chromite, tin, tantalite and various heavy metals are amenable to this principle. Some gold ores contain Free Gold which can be recovered by gravity separation and this is the traditional method used in artisanal gold mining.
Garnet sand. Garnet is composed of natural Almandine rock garnet grains and has been famous for its natural hardness, more angular, sharper edges, durability and abrasive characteristics. It is mainly used for sandblasting and waterjet cutting. Email: [email protected]

The color of quartz sand is also different due to the different impurities contained. For example, because of the impurities such as titanium and iron, it is brownish red or light yellow.The Mohs hardness of quartz is generally 7, and the refractoriness is 1650~1770℃, …
Since the specific gravity of diesel is less than water it floats on top of it. As specific gravity of sand is 2.6 – 2.7 and that of cement is 3.14 – 3.15, i.e. for the same volume occupied by cement and sand, cement is "3.15/2.7 = 1.16 times "heavier than sand.
