2021-4-29  The copper ore forms only 0.7% of the rock. We need to find a number that we can multiply by .007 to get 90 kg. Dividing 90 kg by .007 will give us that number—approximately 12,860 kg.

Copper mining. From ore to copper.

2014-6-13  A typical ore contains only 0.5% to 2.0% copper. It is a measure of the value of copper that it is worth extracting it from such small concentrations. The ore is a mixture of minerals and rock (called gangue). The most common copper minerals are:

Copper Mining and Extraction Sulfide Ores

These mines have now closed and today the biggest copper mines are in Chile (Escondida mine) and Indonesia (Grasberg mine). These produce many millions of tonnes of copper ore per year. The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper
