High Temperature Materials
Processing
• Raw Materials
– Ore or other Mineral (possibly waste)
– Fuel/Reductant

• Product
– Metal
– Glass
– Ceramic

High Temperature Materials
Processing
• Waste/Bi-Product/Co-product
– Slag
– Heat
– CO2/SO2

• Which is Which?

What is an Ore?
• A rock that can be mined to produce a metal, ECONOMICALLY.
• Moving target.

What do we consider in design of process? • Source of raw material
• Form/Chemistry of raw material
– Accessibility of valuable content
– Concentration of valuable content
– Impurities
– Chemical form of valuable content (Oxide/
Sulphide)

• Consistent supply

What do we consider in design of process? • Heat requirement?
• Appropriate Fuels
– Is the fuel also a reactant?
– Does the ore provide its own fuel(Autogenous processing of Sulphides)

• Economic productivity
• Value of product
• Required purity of product

What do we consider in design of process? • Environmental Impact
– Physical
– Economic
– Social

• Becoming the Primary Consideration!

Learning Objectives
• Thermochemical Fundamentals
– Thermodynamics----Can we?---- How can we?
– Heat and mass balance---- how much energy/ product/raw material?

• Be aware of main processes used for materials production
• Be able to relate the design of these processes to the fundamentals.

Characteristics of High
Temperature Processes
• Difficult to Operate/Monitor
• Reactor Materials
