Copper Mining and Extraction Sulfide Ores

The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted

Copper Smelting MetallurgistMineral Processing

2021-1-13  Copper Smelting Process. In the autogenous system described by this report, sulfide concentrate and silica flux are blown into the furnace through a specially designed burner with oxygen and is flash smelted to about 50-percent copper matte. The matte flows down an inclined crucible, countercurrent to the slag flow, to the converting zone at

Copper Mining and Extraction: Oxide Ores

Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide

2018-1-1  The results show that a high percentage of copper was first obtained from acid digested ores and this was then reduced to zero valence using chlorinated chicken waste solution. The leachate had less contamination of alumina, phosphorous, calcium and silica. This is why all copper produced had high purity of over 60% copper.

How much metal does the ore contain? ? World Ocean

In most cases copper ores contain between 0.6 and 1 per cent of copper. Consequently one tonne of ore generates a maximum 6 to 10 kilograms of copper. In the case of platinum the yield is much lower: 1 tonne of ore usually contains between 3 and 6 grams of platinum. Nonetheless it is still worthwhile mining because the platinum price is high.

In most cases, the thin-layer process was used where crushed ores (80% −0.5 in) were stacked in heaps of 3–8 m height after agglomeration and sprayed at flow rates of 6–40 Lhour −1 m −2 with 15–90 days duration for copper oxides and 10–18 months for sulfides. Of note, 80%–85% copper extraction was commonly achieved.

Copper Statistics and Information U.S. Geological Survey

Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.

Silica. Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2). Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
