Typical chromite process flowsheet In some cases, chromite concentrates can be produced by wet gravity concentration alone. In other chromite beneficiation processes, magnetic separation by RED is an essential polishing step. Figure 3 shows a typical flowsheet for upgrading chromite where gravity concentration is followed by dry magnetic ...

Experience indicates that chrome ores are concentrated to best advantage by gravity methods. Since recoveries are generally very poor in the fine sizes, the gravity flowsheet must be designed to remove the chrome as soon as liberated by crushing and grinding. For example, if the chrome is not entirely freed until the or…See more on 911metallurgist
