Abstract. A new method and devices were developed for amber extraction with the help of water, air and vibration. During experimental tests in the laboratory conditions, a large database was created, which was processed by methods of correlation and multifactor regression analysis in order to develop a generalized regression model of dependence between the rate of amber surfacing and the following four independent parameters: density of the medium, frequency and amplitude of vibration, and air volume for the suspension bubbling. Analysis of approximate linear regression model showed that increase of the amber-surfacing rate primarily depended on density of the medium and, in descending order, volume of air, amplitude and frequency of vibration. Rate of surfacing is increased with increased amplitude of oscillations; at the same time, growing of the rest parameters slows down the rate. A generalized regression equation was formulated, which, with high adequacy, describes process of the amber surfacing rate changing depending on the above four parameters, as well as derivative regression equations, in which vibration velocity and vibration acceleration of oscillations are used instead of amplitude and frequency.

Keywords: amber, complex method, density, vibration, surfacing rate.
