Abstract
The present disclosure is drawn to a method for producing magnetite comprising the steps of: forming a ferrous ion solution; forming a ferric ion solution; and mixing and heating the ferrous ion solution and the ferric ion solution with a boric ion solution to precipitate magnetite. The disclosure is drawn to a borate method for producing magnetite wherein a ferrous ion compound and a ferric ion compound, in stoichiometric ratio of 1:2, are precipitated with a boric ion compound.

A method for producing magnetite, the method comprising the steps of:
- a. dissolving in separate solutions ferrous sulfate and ferric nitrate in water;
- b. dissolving sodium borate in water;
- c. combining the dissolved ferrous sulfate and ferric nitrate and adding a stoichiometric amount of dissolved sodium borate to form ferrous borate and ferric borate precipitates and sodium sulfate and sodium nitrate supernatants;
- and
- d. heating the ferrous borate and ferric borate precipitates and sodium sulfate and sodium nitrate supernatants to boiling to form precipitated magnetite and boric oxide supernatant.
