Question

Malachite is an ore of:
A. Copper
B. Iron
C. Zinc
D. Silver

Answer 1

Hint: Malachite occurs in masses and fibrous aggregates. To know which is the element, which has Malachite as ore, we need to know the formula of Malachite at first.

Complete step-by-step answer:
The formula of Malachite is $\text{C}{{\text{u}}_{\text{2}}}\text{C}{{\text{O}}_{\text{3}}}{{\left( \text{OH} \right)}_{\text{2}}}$. So from the formula of Malachite, we can understand that it is an ore of copper.

So the correct answer to the mentioned question is Option A.
The formation of malachite is by the weathering of copper ore bodies in the vicinity.
Malachite’s most striking physical property is its green colour. All specimens of the mineral are green and range from pastel green to a bright green to an extremely dark green and is almost black.

Additional Information: 
Malachite is rarely found at the crystal but when found the crystals are usually acicular to tabular in shape. The crystals are bright green colour, translucent with a vitreous store to adamantine lustre.
Non-crystalline specimens are opaque usually with the dull lustre. Malachite is a copper mineral, and that gives Malachite a high specific gravity, that ranges from 3.6 to 4.0. This property is so striking for a green mineral that Malachite is easy to identify.
Malachite is one of a small number of green minerals that produce effervescence when in contact with cold dilute hydrochloric acid.

Note: Malachite absorbs negative energies and pollutants picking them up from the atmosphere and from the body. It also guards against radiation and clears electromagnetic pollution.
Malachite is often described to be a stone of balance, abundance, manifestation and intention.
