A part of the spent electrolyte enters the cobalt recovery circuit and is purified by the removal of iron, copper, nickel, and zinc prior to the precipitation of cobalt as its hydroxide. This isplished by the addition of more lime to raise the pH until the remaining copper precipitates. This copper is sent back to the copper circuit.
In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore 0.2 . Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant ores are chalcopyrite and bornite, which contain both copper and iron sulphides.

There are certain factors which govern the extraction of copper from an ore, and when these factors are given due consideration, I think we can get about the same extraction with one process as with another. In considering how to remove iron from the electrolyte, we were reminded of the work which had been done by Hoffman at Argentine, where he precipitated iron from bluestone solution
Extraction of Metals. Extraction of Copper.. Copper is sometimes found as native metal.. Copper ores include copperII oxide and copperII sulfide. CopperII oxide can be reduced by reaction with carbon.. Some copper ores may contain only small amounts of copper. These are called low grade ores and have less than 1 copper but they are still used because copper is so valuable.

This means that in order to extract for instance copper, every other metal ion preceding copper in the extraction series has to be removed either by precipitation, which however, is undesirable because of co precipitation losses, or by extraction. In any case one molecule of caustic is consumed per valency of the iron removed. In the case of trivalent iron which is invariably present

The easiest are iron, copper and lead. Over several lessons students can be taught how a metal is extracted and reduced from its ore. As you introduce each new example, increaseplexity of the chemistry. This process will continue during GCSE and A level studies. Your teaching of reduction and oxidation, or redox, at 11 14 creates a conceptual bedrock upon which the rest is built. Begin

In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. Slag is the collectionpounds that are removed.

The copper II ions in the chalcopyrite are reduced to copper I sulfide which is reduced further to copper metal in the final stage. The iron in the chalcopyrite ends up converted into an iron II silicate slag which is removed. Most of the sulfur in the chalcopyrite turns into sulfur dioxide gas.
