    Abstract: A new reagent for the application in the preparation of mineral raw materials, mainly sulphide and oxyde mono-and polymetallic ores of non-ferrous metals, which are used as a corrosion inhibitor of the equipment and grinding bodies and as a selective collector of the wanted metal, is described. The new reagent is a composition of water, mercaptobenzothiazole salts and its derivatives in the quantity of 0-50%, by weight, sodium metasilicates in the quantity of 0,1-10%, by weight, amines in the quantity of 1-5%, by weight, and dithiophosphates in the quantitiy of 0,5-20%, by weight. Also, it discloses the methods for the applicationof that new reagent for the preparations of the copper, zinc and lead concentrates from the sulphide and oxyde ores, for the purpose of further metallurgic processing. In those methods the new reagent is added fully, or in part, in the phase of wet grinding, and in part, as needed, in the flotation phase, in the quantity of 20-300g of the reagent per ton of ore. The application of this new reagent eliminates the need for the use of cyanide and other poisonous depressants of metals, as well as other collectors.
