The most commonly used fine aggregate across world is river sand. River sand is expensive due to excessive cost of transportation from natural sources. Also large scale depletion of the source creates environmental problems. As environmental, transportation and other constraints make the availability and use of river sand less attractive.

Magnetite is an iron oxide mineral and a member of the Spinel group. Magnetite occurs in a variety of rock types and is often the main constituent in black sand. Magnetite is strongly magnetic, and naturally occurring magnetic Magnetite is known as Lodestone.
A material of interest due to its surprising attraction to magnets is some types of black sand, which is actually crushed magnetite In highly volcanic areas this sand can be attracted to magnets through liquid, a process that is highly useful in some gold mining methods, as it pulls impure magnetic sand away from the gold Get More

Magnetite is ferrimagnetic, meaning that it is attracted to a magnet but is not itself magnetic (Dionne 2009). Filler grade magnetite is a free flowing powder which makes shipping and handling straightforward. Magnetite also has a low remanence so that once removed from a magnet, it does not readily remain magnetized.
The formula for magnetite is Fe3O4. Magnetite is a mineral found in nature in the form of iron oxides. This ore is a natural magnet.
Introduction Magnetite, also known as magnetite black sand, is a form of iron oxide. It is a very stable and dense material, and is widely found in nature across the world in a variety of natural settings as a commonplace mineral; it most commonly occurs in nature in a granular form as a sand or grit.
Magnetite has been found in large quantities in beach sand. Such mineral sands (black sands or iron sands) are found in Hong Kong, California beaches and the west coast of the North Island of New Zealand. After it has eroded from rocks, the magnetite is washed to
magnetic susceptibility in experiments of up to 2 kbar [e.g., 76]. However, uniaxial stress will change the susceptibility both in amount and direction, dependent on the orientation of the applied stress relative to the magnetic field. When the applied stress is parallel to the magnetic field the susceptibil
Magnetite is an important iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200 nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

The mineral Hematite is known to form pseudomorphs over Magnetite. Such pseudomorphs are commonly known as Martite, and their appearance may be very similar to regular Magnetite. However, they differ from Magnetite in that they are only weakly attracted to
Magnetite is sometimes found in large quantities in beach sand. Such mineral sands / iron sands / black sands are found in various places such as California and the west coast of New Zealand. The magnetite is carried to the beach via rivers from erosion and is concentrated via wave action and currents.
Sand and gravel bed filters used by many municipal water treatment plants can realize benefits by using heavier aggregates in the sand bed. The heavier specific gravity of magnetite aggregates allow a more aggressive backwash in the cleaning phase without loss of product, and because magnetite is magnetic it can be easily scavenged back from

Jan 31, 20180183;32;Magnetite and hematite can be separated from each other using their magnetic properties. Magnetite is ferromagnetic and hematite is paramagnetic. Therefore, these substances can be separated using low intensity magnetic separation method. Here, an induced roll magnetic separator with a magnetic field with a 0.04 Tesla intensity is used.
Magnetite Healing Properties. Magnetite provides stability, balancing the intellect with the emotions. It brings a balanced perspective and trust in your own intuition. Magnetite attracts love, commitment and loyalty. It alleviates negativity such as fear, anger and grief.
the most common constituent of sand is silica, but many volcanic sands contain quantities of magnetite, these sands are usually dark in colour. What gas is produced when a metal reacts with an acid?
Magnetite is sometimes found in large quantities in beach sand. Such mineral sands or iron sands or black sands are found in various places such as California and the west coast of New Zealand. The magnetite is carried to the beach via rivers from erosion and is concentrated via wave action and currents.

Its the most magnetic mineral that can be found, hence the name. Its also known as Lodestone or Magnetic Hematite. Its black grey in color, but there are also magnetite stones that are grey and silver grey.
