Copper in Concentrate, page-11

Hi thanks for all the replys my thinking is with Owen & Gazisco we are producing concentrate not finished copper product
From the Freeport website
"Copper concentrate is the most basic form of copper product sold by Freeport-McMoRan (FCX). We are one of world's leading producers of copper concentrate. "
Copper concentrate produced at the mines in North and South America generally contain 20 percent to 30 percent copper and is the resulting product after mine ore (containing less than 1 percent copper) has been crushed, milled and concentrated.
hard to find info on what the prices for copper concentrates is or what smelters charge to produce copper.
