The iron content of an iron ore in Laizhou was relatively lower, which was around 15%, and there was 10% of magnetic iron. The particle size of disseminated magnetic iron was uneven. Based on the ore characteristics, Xinhai Mining Technology & Equipment Inc. adopted process of “dry magnetic separation tailings discarding in advance-- stage grinding & stage separation”. By applying this process, the ore amount for grinding was effectively decreased, and the iron recovery rate was improved while the concentrate grade ensured.
Shandong Pingdu iron mine was a typical magnetite mine, and the iron content was around 28%, which included 10% of magnetic iron. ... [more]
