Abstract
The article considers the method of using substandard oxidized nickel ores of the Batamsha deposit and their suitability for sintering. Laboratory studies on the agglomeration of domestic nickel ores with different reducing agents were carried out for the metallurgical evaluation of nickel ores. Agglomeration was carried out according to standard technology, the layer height averaged 24 cm. The agglomeration process proceeded intensively at a discharge of 1100 - 1200 mm Hg, the sintering temperature of which reached over 1200°C. To improve the mechanical properties of the obtained agglomerates, it is necessary to continue research with a change in the composition of charge materials and a metallurgical assessment with the smelting of nickel-containing intermediates.
