Specific gravity is a mineralogists measure of the density of a mineral this is done by comparing the weight of the mineral to the weight of an equal volume of water
Dry weight divided by loss equals specific gravity 4.5. In fact the specific gravity of barite varies between 4.3 and 4.6. This results in part from impurities that may be present in varying quantities in different specimens of this mineral. Most minerals have variable specific gravities. In some the variation may be as much as 25
The mineral barite barium sulfate also known as barytes is most commonly found in hydrothermal veins and as veins in limestone. It is very dense it has a high specific gravity and is relatively soft. Those properties make it an excellent weighting agent in drilling muds for petroleum wells. In fact worldwide oil and gas drilling account for 85 to 90 percent of barite consumption
Feb 28 2013 MINERS NEWS National amp International news from the hard rock The critical factor in barite mining is the specific gravity of the mineral chances are that Nevadas barite mines will continue to see healthy growth for the More detailed
Dec 13 2016 Specific gravity also known as relative density is the ratio between the weight of a stone in air and the weight of an equal volume in water. By convention the temperature of the water is 4 C and at standard atmosphere because the density of water is greatest under these conditions
Specific gravity is a concept that we all have seen but do not know its name. Also the density of the object determines this factor. Moreover in thi9s topic we will discuss specific gravity specific gravity formula and its derivation and solved examples
4.1 Specific gravity apparent may be used as a qualitative test in establishing the identity of a chemical. It may be used to calculate the volume occupied by a product whose weight is known or to calculate the weight of a product from its volume. It may be used to determine the composition of binary mixtures of pure chemicals
Specific gravity measurements in field situations can provide accurate results more rapidly. When the eggshell is dry thickness can be determined and used as a measure of eggshell quality. However specific gravity and eggshell thickness are highly positively correlated and specific gravity measurements are usually all that need to be taken
The density of the aggregates is required in mixture proportioning to establish weight-volume relationships. Specific gravity is easily calculated by determining the densities by the displacement of water. All aggregates contain some porosity and the specific gravity value depends on whether these pores are included in the measurement
To calculate specific gravity for any material we have to use water. But water reacts with cement and forms calcium oxide. So that we are using Kerosene. It doesnt react with cement. This is why we are using 0.79 gcc specific gravity of kerosene in our calculation specific gravity of water 1gcc
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
5.1 Rock riprap and armor stone are composed of pieces of natural rock that are placed on construction projects shorelines streambeds bridge abutments pilings and other structures to minimize the effects of erosion. The ability of rock to withstand deterioration from weathering affects both the effectiveness of the project and its cost. The specific gravity and absorption of rock provide
Specific gravity is a unitless measure and it is the ratio of the mass of a substance to the mass of an equal volume of water. Most rock-forming minerals have a specific gravity between two and
As an answer to both posts about rocks specific gravity is just the ratio of density to the density of water. Water is approximately 1 tm varies slightly with temperature. Be sure to use the intrinsic density of the rocks and volume of hole dont use bulk density of broken rock
Whats the best way to measure specific gravity SG of rocks Check out this article on how you can do your own SG readings on site in your own time
The specific gravity of a mineral determines how heavy it is by its relative weight to water. The specific gravity value is expressed upon how much greater the weight of the mineral is to an equal amount of water. Water has a specific gravity of 1.0. If a mineral has a specific gravity of 2.7 it is 2.7 times heavier than water
Jan 01 2001 Barite. Barite BaSo 4 is a widespread naturally occurring high gravity mineral with a specific gravity ranging from 4.2 to 4.6 and a hardness index of 3.0.It is a non-reactive solid used to increase mud weight up to 22 ppg. Barite was formed under low to moderate temperatures in hydrothermal veins

Here is the formula for specific gravity of a slurry S is S specific gravity of slurry Si specific gravity of liquid phase Ss specific gravity of solids phase Cw concentration of solids by weight Cv concentration of solids by volume EXAMPLE if the liquid has a specific gravity of 1.2 and the concentration of solids by weight is 35 with the solids having a specific gravity of 2.2
In physics a substances specific gravity is the ratio of that substances density to the density of water at 4 degrees Celsius. Because the density of water at 4 degrees Celsius is 1000 kgm3 that ratio is easy to find. For example the density of gold is 19300 kgm3 so its specific gravity is the
Dec 01 2018 Barite with a specific gravity of 4.24.4 and hardness 2.33.5 has been the most common weight material for drilling fluids. The demand of the free world is now approximately 2 million tons per year corresponding to 55 of the total barite production . Conversely barite is prone to sag and so requires viscosifiers and other gellants to
Measuring Specific Gravity. There is a wide range of instruments designed to measure the specific gravity of a material. The hydrometer can be used to measure the specific gravity of any liquid. The device is designed to float freely at the liquid surface with a protruding stem giving a reading corresponding to the specific gravity of the liquid
Apr 08 2019 This makes specific gravity a unitless measurement. Use the ratio W l W water where W l is the weight of your liquid and W water is the weight of water. For example if you weighed 100 mL of acetone at 25 degrees Celsius it would weigh 0.17314 pounds. Weighing the same volume of water at the same temperature would give you 0.22 pounds
