Iron in the Industrial Revolution
As the industrial revolution developed, so did the iron industry. A set of innovations, from different materials to new techniques, allowed iron production to expand greatly. In 1709, Darby became the first man to smelt iron with coke (which is made from heating coal). Although this was a key date, the impact was limited — as the iron was ...

Mercury processing
Mercury processing - Extraction, Refining, Recovery: The pyrometallurgical extraction of mercury from its ore is essentially a distillation process. When heat is applied to the sulfide ore in the presence of air, oxygen combines with the sulfur to form sulfur dioxide, and the metal is liberated at a temperature above its boiling point. The gases are then passed …

An Overview of Nickel Utilization from Laterite Ore | SpringerLink
The technological process of producing nickel pig iron (NPI) by smelting laterite ore in blast furnace is basically the same as that of modern BF smelting for producing pig iron from iron ores, as shown in Fig. 1.12. Initially, the laterite ore is crushed, mixed with flux and fuel, and then sintered in a sintering machine.

23.3: Metallurgy of Iron and Steel
The first step in the metallurgy of iron is usually roasting the ore (heating the ore in air) to remove water, decomposing carbonates into oxides, and converting sulfides into oxides. The oxides are then reduced in a blast furnace that is 80–100 feet high and about 25 feet in diameter (Figure 23.3.2 23.3. 2) in which the roasted ore, coke ...
