To reduce Ti-bearing blast furnace slag wastage, our group previously developed a metallurgical process in which Ti-bearing slag was produced using Na2CO3 instead of CaO. This process increased the TiO2 content—in the form of Na2Ti16O33 (40.93%) and CaTiO3 (42.77%)—of the slag from 22% to ~43%. In this report, a method …

to hot sulphuric acid attack. Due to this expansion, the specific gravity of the spodumene decreases from 3.1 g/cm3 (natural α-spodumene) to around 2.4 g/ cm3 β-spodumene). After roasting, the material is cooled and then mixed with sulphuric acid (95-97%). The mixture is roasted again at about 200°C. An exothermic reaction starts
The bluestone crystals are packed in barrels for the market. One pound of metallic copper with 1.5 lbs. of sulphuric acid of 66° B. will make 4.5 lbs. of crystallised sulphate of copper. The cost of the process of parting by sulphuric acid in Europe is about one farthing per ounce troy of the parting alloy.
