Magnetite - Wikipedia
Magnetite is a rock mineral and one of the main iron ores, with the stone formula Fe 3 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. It is the most magnetic of …

Microbial production of ultrafine-grained …
12.12.1989 · As a result, the extracellular magnetite, produced in the desired ultrafine-grained form, is easily separated from the bacterial cells and readily recovered. Additionally, the cells of GS-15 can be readily grown in mass cultures using cheap materials such as acetic acid and ferric oxide. A further advantage is derived in that this process is carried out anaerobically, and a precise control over …
Simultaneous Removal of Multiple Heavy Metal …
Herein, ultrafine magnetite NPs were synthesized by co-precipitation method and successfully used as adsorbents for the removal of four mixed metal ions (Pb 2+, Cd 2+, Cu 2+, and Ni 2+) from contaminated river water, which represents hitherto the greatest application in removal of metal ions by magnetite NPs. The key to this success was based on the mesoporous property exhibited by the ...
