The value of copper in the different stages of the value chain of copper is explained. It is clarified how the value of the copper content in ores and concentrates, in cathodes, in recycling materials and in copper products is calculated and how it is used in the sales or purchase of copper containing materials. It is shown that the registered copper cathode is the base for all commercial negotiations – not only for cathodes. The role of the London Metal Exchang (LME) and hedging is also discussed.

5. Understanding
Copper
Fragmentation of the Value Chain:
The Reasons ...
The Reasons:
Copper: The final Product of Refining is the Cathode:
• It is solid
• It can be traded
• It can be stored
• It can be transported
• It has to be melted before casting
Aluminium: The final Product of Refining is a Liquid:
• It is liquid
• It cannot be traded
• It cannot be stored over a long time
• It cannot be transported over long distances
• It can be casted directly to billets, bars, and shapes
Copper: Historical Reasons
• Before electrical applications copper products were produced by a
lot of small family owned companies, which partly still exist
• Electrolytical Refining is a total different process than casting or
pyrometallurgical refining
Webinar, European Copper Institute , 4th December 2014
6. Understanding
Copper
Fragmentation of the Value Chain:
... and the Consequences
The Consequences:
• Copper is the most traded Metal in the World
• Hedging plays an important role between all parts of the
Value Chain
• Copper Price is volatile but the risk can be hedged effectively
• Copper is sometimes a victim of speculation
• Transportation Costs are important
• Consolidation is discussed since more than 20 years, but has
happened only within the mining industry

The Value Chain of Copper:
Where to start?
Ore
Concentrate
Anodes
Cathodes
Wire Rod/Shapes
Semis
The Base of all Calculations
in the whole Value Chain of Copper is the
LME Registered Cathode:
• Costs
• Revenues
• Prices
Webinar, European Copper Institute , 4th December 2014
8. Understanding
Copper
The LME Registered Cathode
Trading at the
London Metal Exchange
Requirements for Registration:
• Limits of impurities, e.g. Bi<2 ppm, Antimony <4ppm, Te < 2ppm
• Must have been in the market since at least one year
• Production at least 15,000 tons/year
• Practical Test: Wire Rod Production with 3 Manufacturers with 200 tons each
Drawability, Recrystallization, Conductivity
• Final Decision by the Executive Committee of the LME
Similar Rules for COMEX and Shanghai Future Exchange
There are about 80 registered brands

9. Understanding
Copper
The Cathode
– Base for all Copper Containing Materials
Raw Material
• Scrap
• Concentrate
• Residues
Value:
+ LME for Copper Content
– Processing Charges
– Penalties for impurities
+ Value of other metals
- Losses
Products
• First Use: Wire
Rod, Shapes
• Strip, Tubes, Bars
• Wire
Value:
+ LME für Copper Content
+ Surcharges
+ Premiums (Financing,
Purchasing etc.)
+ Value of Alloying Metals
The Copper Content of a Material
can be hedged at the LME
by buying and selling cathodes:
Contracts can be made for future deliveries for at least 25 t

10. Understanding
Copper
The First Part of the Value Chain:
Primary Production: Mining of Sulfidic Ores
The First Products with a Value are Copper Concentrates
with 20-35 % Copper Content
Webinar, European Copper Institute , 4th December 2014
11. Understanding
Copper
The First Part of the Value Chain:
Value of Concentrates
Value for Mining Companies with own Smelting
and Refining Plants:
+ LME Price for Copper Content

- Costs for Smelting and Refining
(+ Sales of By Products)
Value for Mining Companies without own
Smelting and Refining Plants:
+ LME Price for Copper Content
- Treatment and Refining Charges (TC/RCs)
- Penalties for Impurities
- Losses to be paid
+ Paid Value of other Metals

+ LME Price for Cathodes
+ Cathode Premium
No Valuable By Products!
Technology invented in 1960ies
Now about 19 % of Cathode Production
- No Flotation possible for Oxidic Ores
- Oxidic Ores have got a Value
- Production normally cheaper
than for sulfidic ores

A Side-Step in the Value Chain:
Recycling of Copper/Secondary Production
Scrap can be classified in a different way:
• By copper content, e.g. >90%
• By the processing route like refinery scrap, direct melt, brass mill scrap
• By the physical appearance like bare wires, heavy scrap and light scrap
• By the sources of scrap like turnings, electronic scrap, old radiators
3 big groups of scrap
• Production Scrap (New Scrap)
• Old Scrap
• Complex „Scrap“ like
• Electronic Scrap, Residues etc.

20. Understanding
Copper
A Side-Step in the Value Chain:
Recycling of Copper – What is the Value?
What is the Copper Content?
• Estimation (if >90% Copper)
• Sampling
• Homogenization by Melting a
Sample (Drilling or Sawing,
using the Turnings)
Pricing
• Copper Content minus Losses priced by LME „the
lowest of the Four“: Settlement Buyers and Sellers, 3
Month Buyers and Sellers
• Minus Price for Processing and Refining (if Refining
Scrap)
Webinar, European Copper Institute , 4th December 2014
21. Other Materials
• Electronic Scrap: Sampling, Precious Metals
• Residues: Sometimes without payment
Old Scrap
Normally Copper Content > 90 %
• Electrorefined for Cathode Production
• Evaluation by Estimation
• Volatile Processing Charges historical 100-1000 €/ton
Production Scrap (New Scrap)
Normally Copper Content > 99.5 %
(or pure Alloy like Brass)
• Direct Melted for Products without refining
(e.g. for roofing copper, plumbing tubes)

Germany: DEL-Quotation, MK-Ouotation
Italy:Milano-Quotation
United Kingdom: CRMV

Pricing has to Cover:
Operational Costs + Financing Costs + Costs for Scrap
Financing Costs are big especially for Semis:
Processing time (strip): 3-8 weeks
Stocks because of a big variety of products for a huge number of
applications
Payment Terms have to finance also the metal value
Processing Scrap rate of about 30-60 %
