Nickel mattes; nickel oxide sinters and other intermediate products of nickel metallurgy

HS v2022 Code: 7501

About nickel mattes; nickel oxide sinters and other intermediate products of nickel metallurgy

HS code 7501 covers a range of intermediate products derived from the processing of nickel. These materials play a crucial role in the broader nickel industry, serving as essential inputs for the production of refined nickel and other nickel-based products. The nickel metallurgy sector is a vital component of the global metals and mining industry, supporting a wide array of downstream applications in industries such as aerospace, automotive, and electronics.

Production process

The production of the materials classified under HS code 7501 typically involves a series of pyrometallurgical and hydrometallurgical processes. Nickel-containing ores and concentrates are first smelted to produce nickel matte, a semi-molten mixture of nickel, copper, and other metals. This matte is then further refined through processes like leaching, precipitation, and electroplating to extract and purify the nickel content. Nickel oxide sinters, another key product in this category, are created by sintering (heating and fusing) nickel-bearing materials to produce a porous, high-purity nickel oxide material.

Production inputs

The primary inputs for the production of HS code 7501 materials are nickel-bearing ores and concentrates, as well as various chemical reagents and energy sources required for the smelting, refining, and sintering processes. Specialized equipment such as furnaces, reactors, and electrolytic cells are also essential for the various stages of nickel metallurgy.

Production outputs

The outputs of the HS code 7501 industry include nickel mattes, nickel oxide sinters, and other intermediate nickel products. These materials are then consumed by downstream industries, such as the production of 7502 Unwrought nickel, 7503 Nickel waste and scrap, and 7504 Nickel powders and flakes, which further process the nickel into finished products for a wide range of applications.
