Technology of complex processing of vanadium black-shale ores of Big Karatau
Short description:
Technology of complex processing of vanadium black-shale ores of Big Karatau by the use of sulfuric autoclave leaching in the presence of elemental sulfur is developed. The high degree of extraction of vanadium - 85%, molybdenum - 80%, uranium - 99%, ΣREE - 75% is achieved. Accompanying products - carbon black, aluminum sulfate, silica and metallurgical flux is obtained.
Level of readiness:
The scheme of low-temperature calcinating of vanadium black shale ores of Big Karatau introduced in the LLC «Firma Balausa».
Sulfuric acid test of sulfuric autoclave leaching of black shale-ores Big Karatau is performed at the Stepnogorsk Mining and Chemical Combine (Akmola region).
Pilot testing of technology of complex processing of vanadium black-shale ores of Big Karatau is successfully carried out at the VNIIHT pilot plant (Moscow).
