What is specific gravity of ore?
Specific Gravity, also known as SG, is a measurement that determines the density of minerals. If a mineral has a specific gravity of 2.7, it is 2.7 times heavier than water. Minerals with a specific gravity under 2 are considered light, between 2 and 4.5 average, and greater than 4.5 heavy.
What is the bulk density of iron ore fines?
IMSBC Code information: Iron ore fines contain hematite, goethite and magnetite with varying iron content. It has colour from dark grey, rusty red to yellow. Has bulk density range: 1,500 – 3,500 kg/m3.
What is SG water?
Water has a specific gravity equal to 1. Materials with a specific gravity less than 1 are less dense than water, and will float on the pure liquid; substances with a specific gravity more than 1 are more dense than water, and will sink.
What is blue dust iron ore?
Blue Dust or Friable Powdery Ore. Blue dust is mainly a fine powdery variety of iron ore which has a steel grey color, mainly consisting of micro-platy hematite and martite with a minor amounts of fine grained quartz (Figure 10C).
What is iron ore fines used for?
Iron ore fines are agglomerated into pellets and then indurated using a furnace to create iron ore pellets. These are typically fed to a blast furnace or DRI plant as part of the process to make steel. Designed and supplied the largest straight grate systems in the world.
How do you find the bulk density of iron ore?
The bulk density of the sample is determined by using the formula: B.D =M/V where B.D= bulk density, M= mass (weight) of the sample and V= volume of the sample.
For the calculation, the density of the material and that of the water must be expressed in the same units. Example 1: Calculate the specific gravity of iron. The density of iron is 7850 kg/m 3. The specific gravity of iron-related to water is calculated as follows: Hence, the specific gravity of iron is 7.85.
What is the specific gravity table for metals?
Specific Gravity Table for Metals, Minerals & Ceramics Metal or Alloy Substance Density (kg/m3) Admiralty Brass 8525 Aluminum 2712 Aluminum – melted 2560 – 2640 Aluminum bronze (3-10% Al) 7700 – 8700
What are the risks when carrying iron ore fines?
Liquefaction is one of the main risks when carrying iron ore and in particular iron ore fines. Cargoes that are liable to liquefaction are classified in the IMSBC-code as group A cargoes.
