Mining is important to the economy of Ethiopia as a diversification from agriculture. Currently, mining comprises only 1% of GDP. Gold, gemstones (diamonds and sapphires), and industrial minerals are important commodities for the country’s export-oriented growth strategy.
What are the types of mining activities?
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining.
- Underground mines are more expensive and are often used to reach deeper deposits.
- Surface mines are typically used for more shallow and less valuable deposits.
What is mining explain?
Mining is the process of extracting useful materials from the earth. Some examples of substances that are mined include coal, gold, or iron ore. Iron ore is the material from which the metal iron is produced. The process of mining dates back to prehistoric times.
What is the role of mining?
Mined materials are needed to construct roads and hospitals, to build automobiles and houses, to make computers and satellites, to generate electricity, and to provide the many other goods and services that consumers enjoy. In addition, mining is economically important to producing regions and countries.
What mineral resources does Ethiopia have?
Well known minerals andmineral products available in the country in commercial quantities are: gold, platinum, manganese ore, natural agas, clays and clay products, feldspars, gypsum and anhydrite, slat, lime, limestone, cement, sand, structural and crushed stones, marble, mineral water and pumice.
How do mining activities affect the environment?
The effects can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also affect the atmosphere from the emissions of carbon which have an effect on the quality of human health and biodiversity.
What are the four stages of mining activities?
The mining industry operates through a sequence of stages: exploration, discovery, development, production and reclamation.
What causes mining?
One cause of mining is population growth. With an increasing population, the overall world consumption levels also increase. This means that in order to be able to provide enough goods for the world population, resources have to be extracted at large scale. One great possibility to extract these resources is mining.
What are the 3 types of mining?

Digging deeper: Mining methods explained
- Open-pit mining.
- Underground mining.
- Underwater mining.
What is mining system?
An Energy data Management and Mining System is a set of tools able to collect different kinds of energy data (eg, measurements collected through a district heating system), enrich them with open source information (eg, meteorological data provided by web services), and efficiently store and manage the sensor data and
Why is mining important to our economy?
Aside from supporting thousands of jobs, the mining industry provides raw materials, minerals and metals critical to our economy. They provide the foundations for modern living, innovation and engineering achievements. Take platinum, for example; it is used in more than 20 percent of all manufactured goods.
Does Ethiopia have a mining policy?
The Mining laws of Ethiopia have been issued in 1993 and amended recently, in 1998 that they invite private sector investment and believed to be competitive and attractive as compared to other developing countries mining codes.
What are advantages of mining?

The key environmental impacts of mining are on wildlife and fishery habitats, the water balance, local climates & the pattern of rainfall,sedimentation, the depletion of forests and the disruption of the ecology.
What are the problems of mining?
Across the world, mining contributes to erosion, sinkholes, deforestation, loss of biodiversity, significant use of water resources, dammed rivers and ponded waters, wastewater disposal issues, acid mine drainage and contamination of soil, ground and surface water, all of which can lead to health issues in local
What are the positive and negative effects of mining?
Mining can impact local communities both positively and negatively. While positive impacts such as employment and community development projects are important, they do not off-set the potential negatives. We have found mining can negatively affect people by: forcing them from their homes and land.
How does the mining process work?
The ore and waste areas are marked out and a fleet of excavators and dump trucks mine each area separately. Waste rock is transported to a waste rock stack which is rehabilitated or used to stabilise and fill previously mined areas. Gold bearing ore is transported to stockpiles ready for processing.
How is mining done?
There are four main methods of mining: underground, surface, placer and in-situ. The type of mining method used depends on the kind of resource that is being targeted for extraction, the deposit’s location below or on the Earth’s surface and the capacity of each method to profitably extract the resource.
