Schematic diagram of a new technological system for hydrovacuum granulation (HVG) of slag melts. 1—HVG unit; 2—diffusor with a replaceable nozzle (d—functional diameter of the nozzle); 3—dispersion chamber (r, h—radius and height of the work space); 4—impact area of the associated shock wave with the effect of initiation
The resource utilization of CO 2 and steel slag is an urgent problem that needs to be solved. In order to solve the problem of high added value utilization of CO 2steel slag, thermodynamic calculations were carried out for the preparation of FeMnAlSiC by molten salt electrolysis.Results showed that during 800–1000 °C, the voltage range of
A combined process of carbothermal reduction in vacuum and acid leaching is proposed to produce TiC from titanium bearing blast furnace (BF) slag from Pan Steel in Panzhihua city in China. Thermodynamics calculation shows that TiC can be obtained in the appropriate temperature and pressure range. Moreover, the results of the experiment
The important advantage of CALPHADtype calculations is that slag phase diagrams and slag properties can be calculated for multicomponent industrial slag systems containing 10 or more elements over a wide range of composition, temperature, and oxygen partial pressure. Properties that can be calculated include solidus and liquidus temperatures

A high titania slag that is used as a feedstock for TiO2 manufacturing is obtained by ilmenite smelting (FeO.TiO2). The composition of the slag obtained by smelting is dependent on the composition of the mineral used for slag preparation, i.e., ilmenite in our study. At the laboratory scale, ilmenite slags are mostly obtained by using ilmenite as the
The SM slag was ground for 10, 20, 25, and 30 min using a sealed sample preparation mill. The D 50 values of the SM slag were 121.2, 63.44, 54.06, and 53.43 µm, respectively, as determined using Mastersizer 2000 laser particle size analysis. The particle size distribution diagram for different grinding times is shown in Figure 1.
Yellow phosphorus slag (YPS) is a typical industrial solid waste, while it contains abundant silicon micronutrient required for the growth of rice. The key scientific problem to use the YPS as rice fertilizer is how to activate the slag efficiently during the phosphorite reduction smelting process.
