FEATURES OF THE PHYSICAL AND MECHANICAL CHARACTERISTICS OF DIAMOND POWDER, AC20 GRADE, GRAIN 100/80, AND THE PRODUCTS OF ITS FLOTATION SEPARATION

Abstract

The physico-mechanical characteristics of AC20 diamond powder with a grain size of 100/80 and the products of its flotation separation were studied. Separation was carried out in one stage. The work uses well-known methods of researching synthetic diamond powders. Static strength was investigated using the DA-2 device, morphometric characteristics were investigated using the DiaInspect. OSM device. It was established that the use of flotation separation of AC20 diamond powder with a grain size of 100/80 allows to obtain diamond powder with an increased strength index under static compression by 23.8%, increased uniformity in strength by 25.0%, a significantly reduced proportion of impurities and inclusions, and morphometric characteristics close to the original powder.
