Approximately a third of the Earth's crust consists of iron, which the main ingredient used to make steel. In nature, it exists as an ore, and steel manufacturers must extract it before they can use it. One such ore is a type of iron oxide called titanomagnetite, which is formed as volcanic lava crystallizes. Rivers and streams wash this to the sea, and most of it ends up as …

We reported simple processing of local iron sand in order to increase the purity of magnetic phase. The refining process of iron sand is carried out in two stages, namely the iron sand extract using a permanent magnet and the purification process. The purification process was carried out by co-precipitation method in varying of the dissolving temperatures and volume of HCl.

Once the green sand is used to create a casting, the sand is used and cannot be used again in the casting process. While it is possible to separate out the impurities from sand to reuse it, the process becomes lengthy and expensive. Hence, the services always use new sand for each casting process and use impure sand for other purposes.
