Is Primary Copper Ore Grade Lower Than Byproduct

Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.

Apr 26, 2021 Kovacevic adds that today's open-pit mined copper grades of 0.45 0.65 are being replaced by ~0.3 Cu Eq. grades on a meaningful portion of future production. Assuming $3 lb Cu, that's $19.84 Mt of ore. Sub-$20 Mt does not make the grade for the next generation of bulk tonnage mines, with tens of billions of dollars in upfront capex ahead of them.

Most tellurium used today is indirectly mined, as it is recovered as a byproduct of milled copper, iron, and other base-metal-rich ore bodies containing trace amounts of tellurium-bearing minerals. Globally, primary tellurium sources are large-tonnage, low-grade ores from copper and copper-gold porphyry-type deposits, as a byproduct of copper.
