Abstract:
A method of preparing magnetite particles may include providing a first solution of substantially ferrous sulphate. The first solution may be converted by replacing sulphate ions with chloride ions to produce a second solution of substantially ferrous chloride. The second solution may be oxidized to produce a third solution of substantially iron oxide. A system for purifying a solution of substantially iron oxide may include a solution reservoir, at least one membrane unit, and at least one pump for circulating the solution between the solution reservoir and the membrane unit. The solution may be delivered from the solution reservoir to an inlet of the membrane unit, and/or the solution may be returned from an outlet of the membrane unit to the solution reservoir.

Claim (Index 13):
The method of  claim 1 , wherein the step of oxidizing comprises adjusting a pH of the second solution.
