Class practical. Malachite is a copper ore consisting mainly of basic copper(II) carbonate, CuCO (OH) experiment involves producing copper from copper(II) carbonate. The copper carbonate is first heated to produce copper(II) oxide, which is then reduced to the metal using carbon as a reducing agent.

This is an introduction list that covers the most common carbonates minerals which are compounds of carbon dioxide (frequently called carbonic acid) with oxides of metals. In naming individual carbonates, the name of the metal is used; but if the name of the oxide of the metal is better known, as lime, for example, which is calcium oxide, the name of the oxide will be used instead of the name ...

The estimated average concentration of the rare earth elements in the Earth''s crust, which ranges from around 150 to 220 parts per million (table 1), exceeds that of many other metals that are mined on an industrial scale, such as copper (55 parts per million) and zinc (70 parts per million).
Azurite is a copper carbonate. The chemical formula is Cu 3 [OH CO 3] 2 and results from the oxidation of copper sulfides. Malachite is a copper carbonate with a chemical formula of Cu 2 [(OH) 2 CO 3]. It is a vibrant green color often banded with light and dark greens. Calcite Calcite is a very common sedimentary mineral.
Zinc ore occurs in two types of deposit: as primary zinc ore in thin veins known as rakes, or a secondary deposit formed by weathering of the primary mineral veins. Zinc ore is most commonly found as zinc carbonate (ZnCO 3), known as calamine or smithsonite. It generally occurs as rounded, crystalline crusts or granular, honeycombed masses that ...
