In this study, Fe3O4 nanoparticles (NPs) were synthesized using Indonesian iron sand via co-precipitation. One of the critical parameters in the formation of Fe3O4 by using the co-precipitation method is controlling the ratio of Fe (II)/Fe (III) during the reaction process. The impact of Fe (II)/Fe(III) cation molar ratio (1.5:1, 2:1, 2.5:1) on NP yield and crystallite size …
Investigation on the iron sand characteristic of Syiah Kuala beach in Banda Aceh coastal region has been performed. Samples were prepared by mechanical alloying method …
Representative samples each of which weighing about 40 g from the 306 previously prepared samples were subjected to heavy mineral separation using Bromoform (2.8 g/cm3) and Clerici's solutions (3.7 g/cm3). The obtained heavy fractions from the Bromoform separation were …

either put a magnet in a baggie, then move it over a pile of sand, or put some sand in a baggie, then move the magnet over it. The magnetite grains in the sand will be strongly attracted to the magnet. Using the magnet, the dark grey magnetite grains can be separated from the rest of the rock types in the sand. Magnetite is a mineral containing ...

Exploring the Applications of Magnetite: Unlocking Its Potential. The isolated magnetite, once separated from sand, finds its way into a diverse range of applications. Its magnetic properties make it invaluable in the production of magnets, essential components in various electronic devices, motors, and generators.Additionally, magnetite's use extends to …
Procedure Magnetite preparation. The natural iron sand from Marina Beach Semarang cleaned and washed using aquadest, dried in oven at 80 o C for 24 hours. Natural magnetite was extracted from natural iron sand using permanent magnet until 12 times. This treatment produces powder material dark gray-black color.
Mineral Ores: The alluvial beach sand's main metal minerals are zirconium fluorite, rutile, ilmenite magnetite, and hematite; the main gangue minerals are quartz, feldspar, and mica. The mine adopts a strong magnetic-electric separation process because the magnetite has been removed during the gravity separation process, and the ilmenite has the strongest magnetism among …
Try this magnetism sand experiment with your students or kids at home: Try this activity at a beach or bring some sand home and try a few variations of the activity. Especially if you live along a Great Lakes beach, the sand is sure to contain a fair bit of magnetite. Pass a strong magnet over the beach sand and check your magnet.
