摘要： Purification process for chromium metal is conducted on chromium metal powder which has been compacted without additives at a pressure of at least 50,000 psi (35 x 10 Pa) into a compacted body having a critical diffusion dimension of less than or equal to 25 mm. The purification process uses a hydrogen gas treatment at a temperature of 1200 DEG C to 1600 DEG C for a period of 2 hours to 10 hours using 0.8m per Kg chromium metal of hydrogen gas or more. The hydrogen treated chromium metal compacted body is then further treated under vacuum at a pressure less than or equal to 100 mu m of Hg (15 Pa) at 1200 DEG C to 1600 DEG C for 2 hours to 10 hours. The combined hydrogen and vacuum treatment reduces the oxygen, carbon, sulfur and nitrogen impurities in the chromium metal and results in a chromium metal suitable for metallurgical and electronic applications.

摘要： A method is provided for removing chromium from a chromium containing waste material wherein the waste material is dried by indirect heating, sized to a particle size of less than 0.105 mm, mixed with alkaline and oxidizing reactants, and reacted in a reaction vessel by indirect heating using approximately the stoichiometric oxygen requirement to form a reaction material containing water soluble chromates. The reaction material is cooled and resized, and then subjected to an aqueous solvent extraction to produce a solid phase containing substantially no chromium and an aqueous phase containing water soluble chromates. This aqueous phase is subjected to evaporation resulting in a concentrated chromate phase. The waste material has been rendered non-hazardous and the chromium has been recovered as useful chromates.

摘要： This invention relates to a method of preventing, during the melt-reduction of Cr ore or iron ore, the scatter loss of the ore and coal at the time of charging. In the present invention, the ore and coal are charged down into a furnace from a shoot extended near a furnace port or connected to a furnace body. The ore and coal are charged down into the furnace while a gas is jetted outward of the shoot form nozzles disposed in the circumferential direction inside and near the tip of the shoot so that the raw materials can be charged more effectively while reducing the scatter loss.

摘要： A process for stabilizing chromium in a chromite ore processing residue (COPR) comprises the steps of adding an acid at 14 to consume the excess alkalinity of the COPR, resulting in a pH of less than 10; and adding a chemical reductant at 18 to the COPR to convert any hexavalent chromium present to trivalent chromium. A source of sulfate may be added to the COPR at 20 to reduce heave potential and improve its geotechnical stability. Treated COPR may be encapsulated at 20 in a material suitable to prevent contact between the COPR and water, such as an asphalt.
