Method for extraction and transportation of refractory clays and kaolins includes piling of dumps to inner space of pit, with formation of overburden and production ledges for selective extraction of production rock from inter-stratal layers, with formation of additional ledges and sub-ledges. Extraction of refractory clays and primary kaolins is performed with removal by excavators of surface mineral layer within 98 and 85 meters beneath of found mark of bedding of those. After that extraction is performed by earth-moving machines, with following transportation by pipeline to place of dressing those, this is performed by method of clarification.
