Beneficiation of Oolitic Iron Ores - Hatch

2021-11-9 · Sources of oolitic iron ore worldwide are abundant and ubiquitous, but there is currently no commercial technology to extract iron from oolitic iron ores. Mineral processing of the ore to generate a commercial iron ore concentrate is very challenging due to the nature of these ores. Accordingly, Hatch and Ironstone are developing a new ...

Beneficiation Study on an Oolitic Hematite | Scientific.Net

The oolitic hematite with a lower iron content and a higher phosphorus content will be a potential source of raw iron ore for the Chinese iron and steel industry. The magnetization reducing roasted and magnetic separation is a practical beneficiation process. The results show that the iron content in the concentrate can be increased to 57.63% from 45.95%, the iron recovery up to
