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

cpc code 41421 covers the production of nickel mattes, nickel oxide sinters, and other intermediate products of nickel metallurgy. These materials are crucial inputs for the manufacturing of various nickel-based products, which find applications in diverse industries such as aerospace, automotive, construction, and electronics. The nickel industry plays a significant role in the global economy, contributing to the supply of essential materials for a wide range of industrial and consumer applications.

The production of nickel mattes, nickel oxide sinters, and other intermediate nickel products typically involves a multi-step process. This often begins with the mining and processing of nickel-containing ores, followed by smelting and refining techniques to extract and purify the nickel. Roasting, leaching, and electrochemical processes may be employed to produce the desired intermediate products, which can then be further processed or used as inputs for downstream manufacturing.

The main inputs required for the production of nickel mattes, nickel oxide sinters, and other intermediate nickel products include nickel-containing ores, reducing agents (such as coal or coke), fluxing agents, and various processing chemicals. Additionally, specialized equipment and machinery, such as smelters, furnaces, and electrolytic cells, are essential for the various stages of production.

The primary outputs of cpc code 41421 are nickel mattes, nickel oxide sinters, and other intermediate nickel products. These materials are then consumed by industries producing 41422 Nickel, unwrought and 41423 Nickel powders and flakes, which are used in the manufacture of a wide range of nickel-based products, including stainless steel, superalloys, and rechargeable batteries.
