Study of the micromorphology and health risks of arsenic ...

2021-8-1 · Slag tailings are produced by “cooling-grinding-ball milling-flotation” and other processes of slag, while slag is produced by the flash smelting of the original ore. The utilization and environmental hazards of arsenic in slag tailings have become a focus of attention.

2016-6-8 · The typical process uses crushing, milling and flotation. These operations create excessive liner wear rates during crushing and milling because the bond work index of copper slag is 22 kWh/t and this is considered a very hard slag. The process also has reduced flotation recoveries and requires high flotation reagent consumption.

2017-12-28 · In generally, such copper slag is subjected to recovery copper through flotation, which results in the generation of a large number of flotation wastes, so-called flotation waste of copper slag (FWCS) (Min et al. 2015; Xie et al. 2013). As for the arsenic-containing exhaust gas, it is commonly washed with diluted acid, accompanied by the ...

Flotation. Flotation makes use of density separation, but in a special way. Chemicals are added to change the surface properties of the valuable minerals so that air bubbles can attach to them. The minerals are mixed with water to make a slurry, almost like a watery mud. Air bubbles are blown through the slurry and the minerals attach to the ...

Slag is fed from the silo to a ball mill with a closed-circuit cyclone to achieve a tank cell flotation feed with a particle size of 60 to 75% passing 75 µm. The design mill feed rate is 100 t/h, resulting in a residence time of approximately 13 minutes in the flotation circuit. The current feed rate varies from 60 to 70 t/h.
