COMPAÑÍA MINERA DOÑA INÉS DE COLLAHUASI (Chile) does not produce a single ton of copper and, according to their information, is "among the six main copper producers in the world". How is this possible?

 From the series of publications 
"So they create a fairy tales for the investor" - 
"They draw up the necessary documents
and begin to search for the simpleton..."

COMPAÑÍA MINERA DOÑA INÉS DE COLLAHUASI (Chile)

Owners:
Anglo American plc (44%), (UK)
Glencore (44%), (Switzerland)
Japan Collahuasi Resources B.V. (12%), consorcio integrado por Mitsui & Co., Nippon Mining & Metals Co. y Mitsui Mining & Smelting Co., (Japan)

IMHO, COMPAÑÍA MINERA DOÑA INÉS DE COLLAHUASI (Chile) does not produce a single ton of copper and, according to their information, is "among the six main copper producers in the world". How is this possible?

COMPAÑÍA MINERA DOÑA INÉS DE COLLAHUASI (Chile) produces copper concentrate and molybdenum concentrate, nothing more. A concentrate is stones, sand, minerals, but not metals.

For example, in 2015, COMPAÑÍA MINERA DOÑA INÉS DE COLLAHUASI (Chile) produced 22200 tons of cathode copper.
It seems to me that this is not enough to become "the main copper producers in the world".
