    Effect of pH Modifier Flotation of Chromite. Identical flotation tests were done on samples of Benbow-3 ore containing 30.2 percent Cr2O3 using H2SO4 or HCl as pH modifier. The samples were ground to 100 percent minus 100 mesh, deslimed at a 30-micrometer particle size,

  • Chromite Beneficiation Process
    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
