Iron Mineral Deposits And Projects In People’s Republic

Oolitic siderite and hematite are the main ore minerals. Siderite ore has a grade of about 25%TFe and the hematite ore has grades of 35-47%TFe. The resource of the deposit is a few tens of million tonnes. Because the ore usually contains high phosphorus content, many of the iron deposits of the type have yet to be developed. SRK reviewed and valuated some deposits of this type in Hubei province.
