The Problem with Chromite ProcessingThe Chromite Extraction FlowsheetChromite Process SummaryExperience 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 ore is minus 16 mesh, it is obvious that the plus 16 mesh particles should be removed after stage crushing and griSee more on 911metallurgist Estimated Reading Time 4 mins Chat
