The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density no matter how small or large the fraction is For example ammonium nitrate has a specific gravity sg of 073 while dry ammonium sulphate has a sg of 113 1130 kilogramscubic meter
Aug 18 2020 SG might also be used as Archimedes did to distinguish pure gold SG 193 from 14K gold SG 133 or pyrite SG 51 Some specific gravities of minerals are shown below Online mineral vendors sell equipment for determining specific gravity but it is simple to do in the lab Specific gravity is related to density but it is unitless

If the specific gravity of the iron ore hematite Fe 2 O 3 is 526 and a stream of ore flows into a furnace with a volumetric flow rate of 171 m 3 h What is the mass of iron Fe that will flow into the furnace in one hour in kilograms
Use of Magnetite as an Ore of Iron Most of the iron ore mined today is a banded sedimentary rock known as taconite that contains a mixture of magnetite hematite and chert Once considered a waste material taconite became an important ore after higher grade deposits were depleted Todays commercial taconites contain 25 to 30 iron by weight
Hematite iron ore weighs 515 gram per cubic centimeter or 5 150 kilogram per cubic meter ie density of hematite iron ore is equal to 5 150 kgm In Imperial or US customary measurement system the density is equal to 321504 pound per cubic foot
iron ore minerals with specific gravity of 4 6 Goethite is an iron oxyhydroxide containing ferric iron It is the main component of rust and bog iron ore Goethites hardness ranges from 50 to 55 on the Mohs Scale and its specific gravity varies from 33 to 43 The mineral forms prismatic needlelike crystals needle iron ore

Apr 03 2014 The specific gravity of iron bearing minerals is usually higher than the specific gravity of gangue materials Effectiveness efficiency of the gravity separation depends largely on to proper crushing and sizing of the ore so as to ensure a proper size feed to the gravity separation equipment and also removal of slime from the equipment
Mar 28 2015 A suspension of fine minus 200 mesh ferrosilicon in water is used to create a fluid media with a specific gravity of about 30 Silica rich particles with a specific gravity of about 26 float on the surface of such a medium while the denser and heavier iron ore particles with a specific gravity over 40 settle to the bottom
the mineral on unglazed porcelain or a streak plate I Specific Gravity the relative density G is a number that expresses the ratio between the weight of a substance and the weight of an equal volume of water at 4 C J Magnetism ability of a mineral to be attracted to hand magnet 1 Ferromagnetic those that are attracted to hand magnet 2

For example beryllium has a specific gravity sg of 184 1840 kgm As specific gravity is just a comparison it can be applied across any units The density of pure water is also 624 lbsft pounds per cubic foot and if we know that a sample of aluminum has a sg of 25 then we can calculate that its density is 25 x 624 156 lbsft

Question If The Specific Gravity Of The Iron Ore Hematitel Fe2O3 Is 526 And A Stream Of Ore Flows Into A Furnace With A Volumetric Flow Rate Of 171 M3h What Is The Mass Of Iron Fe That Will Flow Into The Furnace In One Hour In Kilograms
Specific Gravity is the weight of that mineral divided by the weight of an equal volume of water The specific gravity of water equals 10 Most silicate or rockforming minerals have specific gravities of 26 to 34 the ore minerals are usually heavier with specific gravities of 5 to 8
Iron ore is the key raw material for steel production enterpris Generally iron ore with a grade of less than 50 needs to be processed before smelting and utilization After crushing grinding magnetic separation flotation and gravity separation etc iron is gradually selected from the natural iron ore
