Abstract
<P>PROBLEM TO BE SOLVED: To reduce the danger in work and labor, such as neutralization work, by decreasing the amount of use of strong alkali chemicals in separating and recovering cBN from a synthetic lump containing cBN manufactured by a high-pressure process. <P>SOLUTION: The synthetic lump is crushed to ≤20 mm in mean diameter before a process step of recovering the cBN by subjecting the synthetic lump by the high-pressure process to dissolution treatment using an alkaline solution. The ratio of the low-pressure phase boron nitride in the synthetic lump to the cubic boron nitride is reduced to ≤50 mass% by using flotation. At this time, any one or more kinds selected from lamp oil, kerosene, tar creosote, and sodium oleate, and any one or more kinds selected from pine oil, camphor, MIBC (methyl isobutyl carbinol), coniferous tree oil, cresylic acid, creosote oil, eucalyptus oil, and flutole oil are used as the flotation agent. <P>COPYRIGHT: (C)2003,JPO
