The invention relates to the chemical processes for the treatment and extraction of diamonds from synthesis product of synthetic diamonds. The process for the extraction of diamonds from their mixtures with carbon component comprises the introduction into mixture as catalyst cuprum salts, ultrasonic treatment of the obtained suspension for at least 20 minutes at frequency is not less than 50 Hz and at temperature of 45-65 °C, drying at temperature of 150-200 °C, and the heat treatment is carried out at temperature of 330-370 °C for 2-4 hours. The process provides the oxidation selectivity of carbon component, eliminates the use of toxic compounds, and the process stability is increased. |
