FIELD: identification of metal scrap from which metal or metal alloy is produced. ^ SUBSTANCE: method comprises steps of sorting metal scrap by groups according to their content; weighing each group; determining percentage content of elements in groups of metal scrap; determining percentage content of elements in the whole quantity of metal scrap; processing metal scrap; after processing, identifying produced metal alloy or metal and metal scrap by determining percentage content of each element in processed products; comparing results with data of percentage content for the whole quantity of metal scrap. Results are compared according to element or elements contained in metal or in metal alloy and characterized by less loss at processing. Metal scrap may be sorted to groups on base of preliminary analysis. At comparing results, losses for processing are taken into account. ^ EFFECT: enhanced process of identification of metal scrap from which metal or metal alloy is produced. ^ 3 cl |
