Experimental Study on the Mineral Processing of a High-Clay and Lean Hematite

Abstract:

The mineral processing experimental research was carried out on a high mud content lean hematite. The results showed that using the technological flowsheet of “stage grinding- low intensity magnetic separation for obtaining concentrate - high-intensity magnetic separation for discarding tailings-gravity separation(shaking table)”,a final iron concentrate with TFe grade of 65.89% ,yield of 19.35% and iron recovery of 52.32% from the raw ores with TFe grade of 24.07％ was obtained, with the first stage grinding size being 50% -200 mesh and the second stage,95% -200 mesh.
