Patents of the Pedersen Process 1924 1925 1928 Plant built at Høyanger (Norway) to recover alumina from anorthosite consisting predominantly of labradorite. 1940 Alumina production 12,000 mtpy was based on Greek bauxite. 1969 Alumina production of

Minerals | Free Full-Text | Leaching of Ca-Rich Slags

The present research work on the leaching of calcium aluminate slags produced by the reductive smelting of Greek BR consists of two stages. At a first stage, laboratory scale tests were performed by the Laboratory of Metallurgy of the National Technical University of Athens (NTUA), on a calcium aluminate slag, also produced in laboratory scale. This slag was produced using an excess of lime in

Behavior of calcium aluminate cement (CAC) in the presence

Abstract Chromium forms part of numerous processes and its unsafe disposal increases the risk of pollution of soils and aquatic systems, especially hexavalent chromium. This paper deals with the behavior of calcium aluminate cement (CAC) in presence of Cr6+ (0.5, 1.0 and 2.5%) as potassium dichromate (K2Cr2O7). The efficiency of CAC to immobilize Cr6+ was studied using leaching tests.

Carbothermic Reduction of Bauxite Residue for Iron

Greek BR was firstly smelted in an Electric Arc Furnace (EAF) to recover pig iron (>95%). The fluxing strategy entailed feeding lime to favour lower operating temperatures (15001550 °C) and slag viscosities, and to produce a slag containing calcium – aluminate phases (12CaO·7Al 2O 3, 3CaO·Al 2O 3 and CaO.Al 2O 3). The calcium aluminates were identified as thermodynamically favourable in

The calcium content was observed to partially form calcium aluminate and change into sodium calcium silie instead of beginning at 100% excess. Hematite is predicted to initially bind preferentially towards calcium and then shift to sodium instead, forming potential soluble sodium ferrite phases. Actual experimental results further confirmed the linear increase until reaching plateau, albeit
