 — This article presents a two-step method of iron red synthesis based on waste long-term deposited iron(II) sulfate. The first step is the purification of waste iron sulfate, and then the pigment is synthesized by precipitation using a microwave reactor. The newly developed method of purification allows for quick and thorough purification of iron salt. …

 — The colour of maghemite is yellow. Hence it is also referred to as yellow iron oxide. The colour of hematite is red. Hence it is also referred to as red iron oxide. The many applications of iron oxides. As already mentioned in the opening paragraphs of this post, iron oxide and its variants find extensive industrial applications all over the globe.

 — The tones of iron oxide pigments range from yellow, red, brown, green, and black, are non‐toxic, and have a nanometric particle size, which makes them ideal for use as a pigment.

 — The most widespread inorganic pigments are red iron oxides. Production of red iron oxide pigment based on haematite ores of the Yakovlevskoe deposit is promising and it makes it possible to satisfy the demand for high quality and inexpensive pigment. A waste-free scheme is developed for separating iron ore into two types, i.e., red …
