Mass Transfer in the Solid-Liquid System: Mechanism and Kinetics of the Extraction Process

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.

Research of grinding degree influence and polar solvents nature on the efficiency of oil withdrawal from vegetable raw material using extraction method.

The article presents results of experimental data of a study of the extraction process of vegetable oil from soybean and rapeseed in a stationary layer, held using a Soxhlet apparatus. Polar solvents such as methylene chloride and ethanol were used as the extractants. The influence of the grinding degree of the particles of vegetable raw material on the oil yield were investigated. Solvents’ nature impact on the efficiency of the processis established. The results of quantitative analysis are presented in the form of graphical dependencies with the presence of basic process parameters.
