Preventing Chromium Leaching
Aug 19, 2018· Slag A was selected for treatment in the tests. This slag showed high chromium leachability in the previous slurry testing and thus was a logical candidate for testing the chromium-fixing scheme. Slag A6 is essentially the same as unaltered slag A except that it was calcined and melted so as to be more comparable to treated slags A2, A3, and A4.

Characterization and Alumina Leachability of 12CaO·7Al2O3
Jul 20, 2014· Calcium aluminate slag is obtained from blast furnaces when smelting iron-bearing bauxite or red mud. 12CaO·7Al 2 O 3 is one of the main components from which alumina can be leached out [1, 2]. 12CaO·7Al 2 O 3 attracts wide attention because it has better alumina leaching property than other CaO-Al 2 O 3 compounds in sodium carbonate solution
The leachability of a ternary CaO-Al2O3-SiO2 slag produced
In this work, the leachability of a ternary CaO-Al2O3-SiO2 slag produced from smelting-reduction of low-grade bauxite has been studied. The obtained calcium aluminate-slag consists of Ca12Al14O33 and CaAl2O4 phases with minor amounts of complex oxide phases.
