For industrial use, iron-ore concentrates shall correspond to definite requirements regarding both basic substance content – iron as well as phosphorus content. Decreased phosphorus content in iron-ore concentrate can be received by the method of hydrometallurgy (desalinization of phosphorus by mineral acid). On the
experimental base of OJSC VNIIMT, a laboratory research was carried out regarding iron ore dephosphorization; as a result maximum possible content of phosphorus was obtained in a final product. The optimal technological parameters of sulphuric acid desalinization were defined that have an effect on quality of phosphorus removal of iron ore magnetite concentrate: size degradation of roasted concentrate; phosphorus removal duration; pulp heating temperature effect; sulphuric acid-specific consumption.

Keywords: desalinization, iron ore, concentrate, pulp, sulphuric acid, phosphorus content, optimal parameters
