Abstract: Utilization of sillimanite group’s minerals (kyanite, sillimanite, andalusite) in high-aluminiferous refractory industry with a purpose of following utilization in metallurgy to obtain silumine and aluminium by elctrothermic method is impossible without new resources. A one of them is the Andree-Yulyevskaya group of kyanite-bearing technogenic objects. Technogenic deposits formed as a result of alluvial gold deposits’ exploitation at the Southern Urals is an additional source of the complex mineral products. A concentration of minerals of the technogenic objects is higher than initial alluvial placers’ one in n10-n1000 times. During the valuation of industrial potential of the Andree-Yulyevskayakya tetechnogenic deposit, (Southern Urals) a concentrate method of technogenic sands’ sampling has been used which permits estimating a gold placers’ potential of the technogenic objects with poor gold and rutile as a useful additional mineral has been distinguished. As a result of researches a principal technological scheme of technogenic sands’ concentration permitting to obtain kyanite concentrates with content of Al2O3 of 55.5 (%) to 60.2 (%) — the main product and gold-bearing and rutile concentrates as additional products. Complex extraction of kyanite, gold, and rutile from technogenic objects has a commercial attraction of this type deposits’ exploitation.
