THE SOLUTION The plants beneficiate a low-grade ore that was historically considered waste material. This is achieved by removing silica and alumina from the feed material, as well as gravity separating low-grade from high-grade ore. Silica levels, which range from 14% to 20%, have reduced to 6.4% after processing.

Due to the characteristics of siderite, it is a promising iron ore resource. First, it can improve the iron grade after roasting. For example, when the iron grade is 35%, after roasting at 600~700℃, the iron grade can reach 50%. Second, the siderite is transformed into magnetite after roasting, which is easy for magnetic separation.
