Specific gravity sometimes referred to as Density is a useful diagnostic attribute when trying to determine the mineral species of an unknown mineral specimen But textbooks usually describe testing specific gravity using a laboratory balance scale that few of us have in our homes Place the water filled container filled with water
Grindability of granite and Iron‐ore was investigated in this work Samples were collected from Julius Berger Quarry and National Iron‐Ore Mining Company NIOMCO Itakpe

Pulp Densities Pulp densities indicate by means of a tabulation the percentages of solids or liquid to solid ratio in a sample of pulp This figure is valuable in two ways—directly because for each unit process and operation in milling the optimum pulp density must be established and maintained and indirectly because certain important tonnage calculations are
The physical properties of iron ore concentrate such as the morphology of particles specific surface area and particle size distribution have a significant effect on the quality of green pellets [16] [17] [18] The grinding method and its associated parameters strongly affect the physical properties of the iron ore concentrate

Currently approximately billion tons per year of iron ore tailing wastes IOT are generated mainly in Australia Brazil and China This work describes the characterization and application
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 kg per liter Gases are often compared with dry air having a density of grams per liter ounces per cubic foot under standard conditions
Gravity separation of two minerals with different specific gravity is carried out by their relative movement is response to force of gravity and one or more other forces Normally one of the forces is the resistance to motion by a viscous fluid water So besides the specific gravity the factors
Iron ore tailing Iron ore tailing having bulk density 1594 kg/m3 and fineness modulus The specific gravity was found to be particle size distribution is plotted as shown in fig 2 The gradation of tailing used is partly within limits specified in ASTM C 31

Limonite is a mineral that is composed mainly of hydrated iron oxides typically goethite and/or lepidocrocite along with other minerals such as magnetite hematite and quartz It is a yellowish brown to dark brown mineral with a dull or earthy luster and a hardness of 4 to on the Mohs scale Limonite is a secondary mineral that forms from the weathering of other
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 and the concentration of solids by weight is 35%
The Specific Gravity SG is a dimensionless unit defined as the ratio of density of the material to the density of water at a specified temperature It is common to use the density of water at 4 o C 39 o F as reference at this point the density of water is at the Specific gravities SG for common solids and metals can be found in the table below
This table of various minerals ore rock types listed by their tested SG specific gravity complements the BWi List found in earlier post 911 Metallurgist is a trusted resource for practical insights solutions and support in mineral processing engineering helping industry professionals succeed with proven expertise List Table of
Mineral and rock densities are normally expressed as specific gravity which is the density of the rock relative to the density of water This isn t as complex as you may think because water s density is 1 gram per cubic centimeter or 1 g/cm 3 Therefore these numbers translate directly to g/cm 3 or tonnes per cubic meter t/m 3
