Abstract
For today the mineral resources of our planet, especially mineral raw deposits are depleted continuously. Therefore the traditional technologies of extraction and enrichment of mineral raw materials are often unable to provide the profitability of development of mentioned mineral deposits. Thus, the mining industry needs in improving of the existing systems for mineral raw materials separation. The well-known optical sorting method is the most promising in terms of improving of structure and characteristics of devices that realize this method. There are a lot of types of color sorters, but they have a number of shortcomings relating to both schemes of lighting and registration of mineral objects as well as used algorithms of images processing. Often color sorters are unable to divide low-contrast small size mineral objects. This problem can be solved by using of optoelectronic complex for separation of moving small size mineral objects developed by the employees of the chair of optical-electronic devices and systems of University ITMO in Russia. The paper presents the description of structure organization and operating principles of proposed experimental model of optoelectronic complex for separation of moving small size mineral objects.
