Description
This dataset is a market dataset representing the consumption market of the region. The dataset includes the transport of the product from the gate to the consumption end, and the transport service is calculated based on the transport situation of the product in the region. The product represented by this dataset is high-nickel matte, a core intermediate product obtained from copper-nickel mixed concentrate through the pyrometallurgical smelting process (flash smelting furnace - converter blowing - electric furnace cleaning), with significant core characteristics: its main chemical components are nickel sulfide and copper sulfide, with a nickel content as high as 46.6% and outstanding metallic nickel enrichment; it appears as a molten substance or a cooled block, and in addition to the core nickel and copper components, it also contains a certain proportion of iron and sulfur elements, with stable components and strong compatibility with the subsequent extraction process. Its upstream and downstream industry chains are closely connected: the upstream core raw material is copper-nickel mixed concentrate, and downstream it is directly applied in the electrolytic nickel extraction stage as the core raw material for hydrometallurgical smelting or refining processes. After treatment, electrolytic nickel can be efficiently separated and extracted, while valuable metals such as copper are recovered, widely supporting the development of metallurgy, new energy, electronics, aerospace and other key industrial fields, being the key intermediate carrier connecting mixed concentrate and electrolytic nickel products in the nickel-copper smelting industry chain. The entire production process focuses on the pyrometallurgical smelting stage, with the full process covering the entire conversion process from the input of copper-nickel mixed concentrate to the output of finished high-nickel matte. The dataset includes the main raw and auxiliary materials, energy and waste of the production process; infrastructure such as production equipment manufacturing and plant construction is not included within the dataset boundary; the data inventory is formed by merging data from multiple sources.
Activity Description
The entire production process includes the pyrometallurgy process, covering the entire process from copper-nickel mixed concentrate to high-nickel matte.
Process Description
High-nickel matte is a product obtained by pyrometallurgy of copper-nickel mixed concentrate using flash smelting furnace-converter blowing-electric furnace depletion process. The main components are nickel sulfide and copper sulfide, and the nickel content is about 46.6%. It is a molten or cooled block with a high metallic nickel content and a certain proportion of copper, iron and sulfur. High-nickel matte is an important raw material for subsequent hydrometallurgy or refining to extract electrolytic nickel.

In the pyrometallurgical smelting stage, the mixed concentrate is fed into a flash furnace for smelting to produce low nickel matte, which is then blown by a converter into high nickel matte with a nickel content of approximately 46.6%. The flash smelting slag and converter slag are depleted in an electric furnace to produce low nickel matte, which is returned to the converter for blowing. The depleted slag is sent to the slag yard for storage, and the flue gas is used to produce sulfuric acid after dust collection.
