What are the minerals found in Sri Lanka?

Sri Lanka is endowed with a variety of mineral resources, such as feldspar, clays (including ball clay and kaolin), dolomite, graphite, limestone, mica, mineral sands (including ilmenite, rutile, and zircon), phosphate rock, quartzite, and salt.

Why is it important to use mineral resources sustainably?

The aim of sustainable mineral development is to ensure mineral use is kept to a minimum amount without having a negative impact on economic growth. This is achieved by efficient use of minerals as well as recycling and the use of alternative materials.

How can we use mineral resources sustainably?

  1. We can use minerals more sustainably by recycling or reusing them.
  2. Ex: Recycling aluminum beverage cans and scrap aluminum produces 95% less air pollution, 97% less water pollution, and 95 % less energy than mining and processing aluminum ore.

What is an example of an inexhaustible resource?

Solar radiation, or sunlight, in general is an inexhaustible resource. This is so because it is a resource that will not get exhausted in the future ( a few hundred years ) . They are unlimited in nature. For example , air, water, sunlight, biomass are inexhaustible sources of energy.

What is exhaustible resources give example?

Examples of exhaustible natural resources are fossil fuels such as oil, coal, and natural gas, as well as minerals like iron, copper, and aluminium. The main question is whether it is possible to maintain a non-declining per capita income when a natural resource is an important factor in production.

How can we use mineral resources?

Mineral resources are a vital part of any economy, modern or ancient. Since the birth of civilization, man has used these resources for pigments, metals, glasses, ceramics, cements and much more.

What are three ways to use mineral resources more sustainably?

We can use mineral resources more sustainably by trying to find substitutes for scarce resources, reducing resource waste, and reusing and recycling nonrenewable minerals.

What are the major mineral deposits in Sri Lanka?

Presently raw graphite is exported at around US $ 1 per kg where as the price of graphene is over US $ 6,000 per kg. Mineral Sand: A well known mineral sand deposit in Sri Lanka is at Pulmoddai, north of Trincomalee. The major minerals in this deposit are ilmenite and rutile.

Where are the ilmanite and rutile in Srilanka?
