Where does the raw material come from, to be melted at Affi's?
Affi does not operate a mine, it does not even hold shares of a mining
enterprise. A 3.7% share of Freeport, West Papua, was sold in 1990. Ore
concentrate is bought preferably on long term contracts from a couple of
suppliers. In its business reports, suppliers of Affi are quoted countrywise.

In 1999/2000, total copper production made a leap, because Affi aquired
the smelter "Kayser" at Luenen, Westfalia. At Luenen, only scrap is processed.
Scrap input to the utility at Hamburg was decreased in favour of Luenen.
In 2001, smelter capacity for ore concentrate at Hamburg was expanded from
740 000 to 1 000 000 tons/year. Since exact figures are not available,
an average copper content in concentrate is applied to all countries.
To find out, which mines of the different countries supply Affi, we
checked other publications, e.g. the US
Minerals Yearbook.
For some countries, like Argentina and Portugal, there is but one mine,
for countries with more alternatives, sufficient side information was found
on the web, to produce the following list of mines, that regularly supply
Affi:
-
Alumbrera, Argentina
-
Collahuasi, and Escondida, Chile
-
Batu Hijau, Indonesia
-
Ok Tedi, Papua Newguinea
-
Antamina, Peru
-
Somincor, Portugal
