The Problem with Chromite Processing 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 …

The aluminothermic process begins with the roasting of fine ore, soda, and lime in air at 1,100 °C (2,000 °F). This creates a calcine containing sodium chromate, which is leached from the insoluble gangue and then reduced and precipitated as Cr 2 O 3.The Cr 2 O 3 is blended with finely divided aluminum powder, charged to a refractory-lined container, …

On open furnaces with low-quality raw materials (e.g., unscreened lumpy ores), Cr recoveries to the alloy are generally below 80%. With screened lumpy ore, together with briquetted fines, the chrome recovery should increase to about 80%. When lumpy and fine ore are replaced by pellets, the Cr recovery responds favorably and …
