Kimony was founded by geologist Anthony Eden Greville and his wife Rina Greville in South Africa in the 1970's to supply the cement industry in Southern Africa with magnetite iron …
Ferrous iron oxide magnetite (Fe304) is the concentrate of magnetite ore that contains 96% magnetics. Higher iron levels can be achieved through further magnetic separation and milling. Durable and stable Grain size ranges from coarse to ultra-fine Meets requirements of centrifuge-assisted dense medium separation and coal preparation Data Sheets
All magnetite ores from South Australia produce concentrates with low levels of deleterious elements inclusive of those deposits with relatively coarse grinds in the range 75–125 µm. Magnetite concentrate grades range from 65 to 70% Fe with the variation in iron grade largely sympathetic according to the silica content.

Materials and mix proportions Two types of high-strength shielding concretes containing magnetite aggregate were prepared. Concretes have been produced using Rapid Hardening Portland Cement CEM I 42,5 R and silica fume additive (10 %wt). Binder and water in each composition was constant and water-to-cement ratio (w/c) was set at 0.35.

In the presence of mineralizers such as 0.1 M HI or 2 M NH 4 Cl and at 0.207 MPa at 416–800 °C, magnetite grew as crystals whose shapes were a combination of rhombic-dodechahedra forms. [15] The crystals were more rounded than usual.
Abstract: Discusses crushing and handling of the magnetite iron ore, which was used as the aggregate for a dense shielding concrete, and the physical properties and costs of magnetite ore concrete are compared to those of other concretes. The mix used had a compressive strength of 4000 psi in 10 days.
Cement pastes with different magnetite powder to cement ratios, up to 50% by mass, and exposed to temperatures of 200 °C, 300 °C, 450 °C and 600 °C, were prepared.
In the initial stage, the ore must be condensed in several stages of operation, including: crushing, grinding, sifting, washing, using a magnetic separator, or by flotation. Concentrated solution usually contains 60 to 65 percent iron, 8 to 12 percent silica.

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 2+ Fe 3+ 2 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. With the exception of extremely rare native iron deposits, it is the most magnetic of all the naturally occurring minerals on Earth.
Concrete @ your Fingertips - The Concrete Society. The density achieved will depend on the type of aggregate used. Typically using barites the density will be in the region of 3,500kg/m 3, which is 45% greater than that of normal concrete, while with magnetite the density will be 3,900kg/m 3, or 60% greater than normal concrete.
The results of a theoretical option study for high capacity processing of a hard, fine-grained silica-rich magnetite ore is presented in this paper, with the emphasis on comminution …

In coal preparation, the mineral magnetite (FeO, Fe 2 O 3) has become the most commonly used material, not only because it fulfils all the above criteria, but also because of its worldwide occurrence either as an iron ore or as a by-product of mining operations for other minerals. Like any mineral, magnetite rarely occurs in the pure state and ...
A relatively common, black, metallic mineral, magnetite is also one of modern society's most important iron ores, occurring in a variety of igneous rocks, pegmatites, contact metamorphic rocks and hydrothermal veins. In our modern Earth, …

This property allows magnetite to be used in the manufacture of heavy concrete, water filtration, coal mining, landscaping and production of certain iron-based chemicals. When magnetite is added to a concrete mix, it produces heavy concrete, which is twice as dense as standard concrete.
Meanwhile, national iron sand is commonly used for cement industries and its potency has not supported national steel industries yet because of low iron content (45-48 ). Types Of Iron Ore: Hematite Vs Magnetite Inn. The cement industry uses an estimated 5-10,000 tonnes to produce special details .
There are immense natural deposits of magnetite, also of titanium ore, which latter is not of value for steel making, and it would surely be possible to obtain the necessary quantities in...
A mix containing 470 pounds of cement, 1755 pounds of coarse aggregate, 2025 pounds of medium aggregate, and 2070 pounds of fine aggregate and with a water-cement ratio of 0.53 produces concrete with a unit weight of 235 to 245 pounds per cubic foot. Other typical properties are: Ultimate compressive strength. 3600 psi. Ultimate tensile strength.
