The work is devoted to development of technical vision system for the concentration tables. It is shown that new technologies applied to the design of concentration tables will significantly help companies, specializing in extraction and handling of common minerals in deep processing of construction sands in order to obtain more expensive products. Technical vision hardware and software complex is considered as one of automation systems, that can greatly improve productivity of concentration tables, provide energy, human and essential mineral resource saving (e.g. of such minerals as titanium-zirconium raw material). Described is the mechanism of different fractions dividing on the concentration table. Shown is the process of dividing line recognition by technical vision system. Depicted is the system structure and the used elements. Pictured is the software general operation including camera image analysis before making decisions and hardware control.

This paper is devoted to combining ecology challenges and STEM technologies. We consider ecology as an integral part of STEM process. The including of ecology in the STEM allows not only to develop mathematician calculations and engineering skills but also forms students’ ecological consciousness. The attempt to combine ecology and STEM is aimed to make the knowledge in ecological sphere more practical. STEM education can help in solving the main ecological problems and challenges. STEM lessons, projects, conferences, exchanges could explain and give a living example of damages caused to our planet by irrational using of natural resources. It can improve public awareness and show the careful attitude to our planet.
