Pulsed electric discharge in an aqueous medium for processing raw amber

The paper presents the results on the use of pulsed electric discharge in an aqueous medium (Yutkin effect) for processing raw amber. The proposed method allows to achieve a high degree of purification of the surface of amber, including purification from the oxidized crust, almost without destruction of the original pieces, while there is no sticking of small fractions and other negative phenomena. Using the same method, but in other treatment modes, it is possible to crush off-grade feedstock for further refining. Fractional composition of the obtaining material and the degree of its purification are regulated by the treatment mode. So three technological processes (washing, peeling and crushing) can be carried out using only one installation, which significantly reduce the cost of industrial implementation.
