Steel slag is a byproduct from either the conversion of iron to steel in a basic oxygen furnace, or the melting of scrap to make steel in an electric arc furnace. This paper reviews the production, processing, and characteristics of steel slag, and its use as a cementing component in different cementing systems.

The copper smelting process produces plenty of copper slag every year, which is a hazardous solid waste, but a secondary resource. In the present study, the extraction of copper, nickel, and ...

The feed material (copper slag) used in this study was sourced from a mineral processing plant called BCL in Botswana's Northern region. The copper slag …

The present study focuses on the experimental investigation of sulphatizing roasting of flotation tailings from copper slag processing using iron (II) and (III) sulfates followed by water leaching. The effect of temperature, duration of sulphatizing roasting, as well as the amount of iron sulfates on the conversion of zinc, copper, iron and other components in …

The feed material (copper slag) used in this study was sourced from a mineral processing plant called BCL in Botswana's Northern region. The copper slag was sampled at different points at the slag dump, and tests were done on it in the laboratory to upgrade the copper mineral for the next phase of experimental test works [ 15 ].

Globally a large volume of copper slag (Table 1) is produced which can be approximated to 2.2 tons of slag generated for every ton of copper produced [9].The annual worldwide production of slag is approximately 24.6 million tons in the early century [6, 7] and increasing at a rate of 11% per year [6].Table 1 illustrates the magnitude of slag …

In the production of copper from sulfide ore, slag accumulates at the processing plant. In the present work, the phase transformations that occur in such slag during its reduction by the gasification products of carbon at 1100 and 1200°C are investigated. Experiments show that most of the iron present in such slag may be …
