Basics of slag production Article on the slag industry
Oct 27, 2011BOS Slag. Process. When molten iron (referred to as “hot metal”) from the blast furnace is to be converted into steel, the main tasks are the removal of carbon, silicon and phosphorus. The LD (Linz-Donawitz) process is by far the most widely used, and takes its name from the towns where it was developed.

Analysis and multi-objective optimization of slag powder
Nov 01, 2020The entire slag powder process is shown in Fig. 2. Firstly raw slag materials are transported into the vertical mill through the conveyor belt after iron removement and drying process. The raw slag is ground under the pressure of the grinding roller and the millstone. The slag powder is blown to the upper part of the vertical mill by the hot gas.

11.18 Mineral Wool Manufacturing
illustrates the mineral wool manufacturing process. The first step in the process involves melting the mineral feed. The raw material (slag and rock) is loaded into a cupola in alternating layers with coke at weight ratios of about 5 to 6 parts mineral to 1 part coke. As the coke is ignited and burned, the mineral charge is heated to the molten

Converter Slag an overview ScienceDirect Topics
Actually, the slags form a major source for world’s vanadium already (74), but the processes are mainly focused on acid-enhanced leaching of vanadium directly from fresh converter slag. If the slag is utilized for mineral carbonation, the mineralogy will change, resulting in different extraction rates.
