Assuming that a barite ore consists of discrete barite (BaSO 4) and quartz (SiO 2) or that chromitite ore consists essentially of chromite and pyroxene minerals, it should be possible to estimate bulk density based on XRF ‘whole rock’ analyses. An example is barite ore in which pure barite …
To Calculate the Weight of a Measured Volume of Mineral or Rock.—Multiply the cubic feet by 62.4 and then multiply by the sp. g. of the stuff, the answer gives the weight in pounds. For example, 100 cubic feet of quartz weighs 100 x 62.4 x 2.6 = 16,224 lbs.
The high specific gravity of barite makes it suitable for a wide range of industrial, medical, and manufacturing uses. Barite also serves as the principal ore of barium. Barite Rose: This "barite rose" is a cluster of bladed barite crystals that have grown in sand, incorporating many of …
When filled to a depth of 200 mm with a certain oil, weighs 35.4 N. Calculate the specific gravity of the oil. A mixture of methanol (methyl alcohol) and water contains 30.00% water by mass.
S.G. is defined as the weight of a body compared with the weight of an equal volume of pure water. The specific gravity of a gemstone is a ratio which could be of great help in identifying gemstones. Although a gemstone cannot normally be identified by its S.G. alone, together with other measurements this can help in narrowing down the range of possibilities.
May 13, 2020· Specific gravity, ratio of the density of a substance to that of a standard substance. Solids and liquids are often compared with water at 4 C, which has a density of 1.0 kg per liter. Gases are often compared with dry air, having a density of 1.29 grams per liter (1.29 ounces per cubic foot) under standard conditions.
mineral’s specific gravity (i.e. the hydrostatic method described in mineralogy textbooks, with various instrumental applications reviewed by Muller, 1977). In practice, a sample is weighed twice, once in air and once in liquid, and the difference in weights is used to calculate the specific gravity …
As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that a sample of ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft.
Assume the only test equipment available is that listed below (i.e., you do not have a specific gravity balance handy, and you don't happen to have an electron microscopy / EDS setup in your classroom.) Barite or "heavy spar" has some distinct chemical properties that aid in its identification.
Specific Gravity Of General Materials Table The specific gravity of all other materials , and if we know that a sample of ammonium nitrate has a sg of 073 then we can calculate that its , Barite , crushed ....
Specific gravity = 705 divided by 62.4 = 11.3 specific gravity OK? My method: The weight of the specimen in water is pulling on the string less because a portion of the weight is pushing down on the scale as you suspend the mineral. In my method the same example of lead results in these measurements: Dry weight (DW): 705 grams
Measure the increase in volume caused by the dry solids displacing some of the water. Assume the new volume is 550 c.c. The displacement, then, is 50 c.c. (550-500). Divide the weight of the dry solids (200 gr.) by the difference in volume (50 c.c.). The result, 4.00, is the specific gravity of the dry solids.
how to measure specific gravity in barite rock. ARTICLES - CSA Global. ... To calculate the specific gravity (SG) of an object, you compare the object''s density to the density of water: Because the density of water in g/cm 3 is 1.0, the SG of an object is will be almost the same as its density in g/cm 3. ...
As for how you actually measure the specific gravity of a gemstone, you need a hydrostatic balance. The stone in question is first weighed in air and then weighed again while immersed in water. Once those numbers are received you simply divide the weight of the stone in the air with the difference bweteen the weight in the air and water.
Water has a density of 1.0 g/cm 3, so the numeric value of specific gravity for a rock is the same as that for density. Because specific gravity is a ratio, it has no unit. Specific gravity is easier to measure than density. In order to measure specific gravity you need a balance or scale with a hook on the bottom.
By Steven Holzner . In physics, a substance’s specific gravity is the ratio of that substance’s density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1,000 kg/m 3, that ratio is easy to find.For example, the density of gold is 19,300 kg/m 3, so its specific gravity …
Nov 19, 2008· pls can you help me to qout me the cubic meter to metric ton of barite. this is the specific gravity for the barite (2.1-2.2) Thanks
Specific gravity is a dimensionless unit that defines the ratio between the density of a rock and the density of water at, typically, 4 Celsius. Density is an important characteristic of a rock, since this parameter helps to identify the rock type and its geologic structure. To calculate the rock …
Jun 14, 2019· Barite is much heavier, however. Its specific gravity is around 4.5 (by comparison, that of quartz is 2.6) because barium is an element of high atomic weight. Otherwise, barite is hard to tell apart from other white minerals with tabular crystal habits. Barite also occurs in a botryoidal habit.
It really depends on the particle size of the product and whether it is loose or compacted. A typical 1u median particle size (mps) product might be ~60 lbs/ft3 loose and ~100 lbs/ft3 compacted. A ...
These test methods cover the qualitative and quantitative analysis of the composition of rubber products of the "R" family; describe the determination of the specific gravity (relative density) and density of solid plastics in forms such as sheets, rods, tubes, or molded items; and the determination of the density and relative density of non-cellular plastics in the form of sheet, film, tube ...

Pure barium sulfate has a specific gravity of 4.50 g/cm 3, but drilling-grade barite is expected to have a specific gravity of at least 4.20 g/cm 3 to meet API specifications. Contaminants in barite, such as cement , siderite , pyrrhotite , gypsum and anhydrite , can cause problems in certain mud systems and should be evaluated in any quality ...
Jun 26, 2015· The Specific Gravity (SG) of a substance is a measure of its density. It is expressed as the ratio of the weight of a given volume of the substance compared to the weight of an equal volume of a reference substance – usually water .An alternative term sometimes used is: …
May 08, 2018· Specific Gravity Relative density: the ratio of the density of the material to the density ... • The curved lines means that a quartz –barite rock will have a higher volume of quartz than expected from SiO2 content ... • We need to measure mass and
The density of any material is derived by multiplying the specific gravity of that material by the density of pure water. For example, the specific gravity of barite is 4.2 and its density is equal to (4.2) (8.33 lb/gal) = 35 lb/gal. Conversely, to convert from density to specific gravity, divide the density of a material or mud by the density of pure water.
how to measure specific gravity in barite rock. The problem with determining the specific gravity of pumice is that it is a kind of rock . Should you measure the specific gravity of the aggregate /air mixture? Or should you eliminate the air, and measure only the stone? For this reason the question is vague.
Before adding the rock, place enough water in the cup, so the rock will be completely submerged. Measure the volume of water. Add the rock, being sure no bubbles stick to the rock. Measure the resulting volume of water. Subtract the initial, water-only, volume from the final, water and rock, volume to find the volume of the rock.
