The obtained calcium aluminate-slag consists of Ca12Al14O33 and CaAl2O4 phases with minor amounts of complex oxide phases. A leaching series have been …

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.

stages [3, 4, 5]. The first is the smelting of the bauxite ore to produce calcium aluminate slags and pig iron as a by-product to feed the cast iron industry. In the second stage the slags are leached with sodium carbonate solutions to dissolve the aluminate minerals and leave behind a mostly calcium carbonate product referred to as grey mud.

geopolymer with a UCS of 24.5MPa. The increase in strength was due to the formation of Calcium Silie (Aluminate) hydrate. The aluminate activated FeCr slag geopolymer was the most competent of all geopolymers synthesised as it resulted in over 97% immobilisation of Fe, Zn, Mn, Ni and Cr.

Jul 03, 2020· Slag conditioner plays a vital role when we are into the production of synthetic slag. The synthetic slag consists of several calcium aluminate which occur in the entire process and from which very few are only stable. The calcium aluminates are some specific kind of salt made from calcium hydroxide and aluminic acid.
