CN-108588425-B chemical patent summary.

nickel processing

The slag is drawn off, leaving a matte of 70 to 75 percent nickel. Because the conversion of nickel sulfide directly to metal would require an extremely high temperature (in excess of 1,600 °C [2,910 °F]), the removal of sulfur at this stage of the converting process is controlled in order to produce the 70–75 percent nickel matte, which has a lower melting point .

Matte (metallurgy)

Matte is a term used in the field of pyrometallurgy given to the molten metal sulfide phases typically formed during smelting of copper, nickel, and other base metals. Typically, a matte is the phase in which the principal metal being extracted is recovered prior to a final reduction process (usually converting) to produce a crude metal.

Slag

Slag is a by-product of smelting ( pyrometallurgical) ores and used metals. [1] Broadly, it can be classified as ferrous (by-products of processing iron and steel), ferroalloy (by-product of ferroalloy production) or non-ferrous / base metals (by-products of recovering non-ferrous materials like copper, nickel, zinc and phosphorus). [2]

WO2017121663A1

This slag is characterized by a composition according to : 3% < Li 2 O< 20%; 1% < MnO < 7%; 38% < AI 2 O 3 < 65%; CaO < 55%; and, SiO 2 < 45%. The present invention concerns a slag composition having a high lithium content, suitable as additive in the manufacture of end-user products, or for the economic recovery of the contained lithium.

Nickel Slag

Three steel slag samples and two air-cooled nickel slag samples were used in the preliminary expansion force test and autoclave disruption test. Basic oxygen furnace (BOF) steel slag samples BOF-1, BOF-2, and BOF-3 with nominal particle size of 20 mm (16–20 mm) have disruption ratios of 3%, 2%, and 5%, respectively, after an autoclave disruption test.

Comprehensive utilization of nickel metallurgical residue

Abstract: As an industrial waste slag,nickel slag produced in the nickel smelting process contains many valuable metals,such as iron,nickel,cobalt and copper.With the rapid development of industry in recent years,the output of nickel slag is increasing,which not only takes up a lot of soil and wastes metal resources,but also seriously pollutes the environment.On the basis the …

Metallurgical Slag

 · Summary. The slag cover protects the metal and matte from oxidation and prevents heat losses due to its poor thermal conductivity. In order to achieve these objectives, slag must possess a certain optimum level of physical properties, such as low melting point, low viscosity, low surface tension, and high diffusivity; and chemical properties ...
