Materials engineering-technological principles of creation of ceramic refractory profile specialties for chemical and thermal processes of extraction of precious metals from man-made sludge (Message 1)

A multi-stage temperature-time schematic diagram of step-by-step chemical and thermal processes (CTP) for the separation of precious metals from man-made sludge through melts of oxide-alkaline slags has been analyzed; on the basis of aluminosilicate and magnesite-periclase manmade raw materials, (import-substituting) technologies have been developed for the creation of thermocorrosion-erosionresistant ceramic-refractory materials‒products (crucibles, sherbers, fonts) for the CTP of extracting precious metals from man-made sludge.
