Laboratory selective disintegration of kimberlite

Abstract

For the selective disintegration of kimberlite and dissociation of diamond crystals preserving their natural integrity undisturbed, the authors have designed a tool with cutters having hardness lower than diamonds but higher than binding minerals in kimberlite. The article gives the test results on the prototype of the heterogeneous material disintegrator on soft kimberlite extracted from Manchary pipe. The prototype includes disc brushes made of high-strength steel wire. The prototype realizing selective disintegration is a preproduction model of lab, semi-commercial and commercial disintegrators. The method is applicable to recover hard particles from geological samples.
