Abstract: 
The mechanism and kinetics of the target components extraction from mineral raw materials (sulfur from sulfur ore by tetrachlorethylene, Al2O3 from bauxite specs by NaOH, copper from ore and malachite by hydrochloric acid), as well as vegetable oils (from amaranth, amaranth hybrid and сamelina by organic solvents) have been studied. Experimental studies to confirm the diffusive nature of the target components extraction from mineral sources have been conducted. Diffusion coefficients for mineral samples have been obtained. It has been established that the target component extraction from the plant raw material occurs by the internal diffusion transfer of the component to the surface of the phase contact and the external diffusion from the surface to the liquid volume. Kinetic and diffusion coefficients for the samples of vegetable raw materials were determined.
