Spent carbon anode (SCA) is a typical global hazardous solid with high risk of environmental pollution.We therefore report for the first time a novel co-treatment technology for SCA and copper slag involving clearly defined transformation paths for F, Cu, Pb and Zn. The results of the investigation showed that the F and C contents in the …
A number of recycling options are possible for the management of ABM. Spent blasting abrasives have been used as a feedstock material in the production of Portland Cement. (Salt et al. 1994, Brabrand and Loehr 1993) This recycling option is currently practiced by the Tampa Port Authority, along with three cement kilns throughout the state of ...
1. Introduction Copper slag is a waste produced during pyrometallurgical processing of metals from copper concentrates. The decomposition and oxidation reactions of the sulphide minerals in the concentrate leads to the production of three separate …
The optimum reductant addition of spent cathode carbon block (SCCB) and spent SiC side block (SSCB) was 8–12 wt %, and the copper and cobalt recovery reached more than 98 and 96%, respectively. The addition of 10 wt % CaO for SCCB improved slag viscosity and promoted the separation between slag and matte/alloy and fixed fluorine in …
