The analytical results in Table 1 show that the slags tested varied in total copper content from 5.2% to 15.1% Cu with the Escondida slag having a mid-range value of 9.8% Cu. The CaO/Fe ratio was typically 0.63 except for the Escondida slag where it was 0.55. In general, the higher the copper content the more oxidised the slag.

Co-catalytic effect of WS2 on the copper slag mediated peroxodisulfate activation for the simultaneous elimination of typical flotation reagent benzotriazole and Cr(VI) Article Aug 2022

0. Thionocarbamates are the group of collectors that are mostly used for flotation of sulphide copper minerals, alone or in combination with xanthates depending on a mineralogical composition of the ore. Collectors are a group of reagents used in flotation for enhancing hydrophobicity of wanted minerals. They are organic compounds which …

The nature of copper slag flotation is unique due to the high temperature in the flotation pulp and high metallic copper content in the feed. Despite its great potential for valorizing slag, copper slag flotation remains challenging due to the deactivation of traditional dithiocarbonate (DTC) collectors (e.g., butyl xanthate) under high temperatures.
