Mining waste has different characteristics depending on the type of ore being mined. Our Swedish ores can be roughly divided into oxidic and sulphidic ores. The oxidic ores predominate in Norrbotten's iron ore field, while the sulphidic ores are more prominent in, e.g. the Skellefteå field in Västerbotten.

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Advantages of mining ores Metals that can be found from mining ores Aluminium = 32 million tonnes Copper = 12million tonnes Gold = 2600 tonnes Lead = 3800000 tonnes Tin = 660000 tonnes Zinc = 7100000 Metal ores Most metals must be extracted from rocks, called ores, in the Earth's
Occupational and environmental exposure to heavy metals, silica, and asbestos can occur during mining and milling operations. The smelting process (extracting the metal from the ore) is associated with the highest exposures and environmental releases.
Direct Investment (FDI) in the mining sector and exploration of metal and non-metal ores under the automatic route, which will propel growth in the sector. Power and cement industries are also aiding growth in the metals and mining sector. Demand for iron and steel is set to grow, given the strong growth expectations for the construction sectors.

This U.S. industry comprises establishments primarily engaged in developing the mine site, mining, and/or beneficiating (i.e., preparing) metal ores (except iron and manganiferous ores valued for their iron content, gold ore, silver ore, copper, nickel, lead, zinc, and uranium-radium-vanadium ore).
type of metals or materials to be extracted from the earth. The majority of proposed mining projects involve the extraction of ore deposits such as copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum. The environmental impacts of large-scale mining projects involving these metal ores are the subject of this Guidebook.
The Mining sector covers the extraction and processing of metal and mineral ores and deposits, including coal, copper, iron, limestone, nickel, precious metals, potash, uranium, diamonds, minerals, rare earth elements and much more.
There are many problems with mining metal ores, such as pollution to the surrounding environment. Mining often means cutting down large areas of land so they make the ores a lot more accessible.

Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
There is no ore dust or direct ore exposure to the environment and a lower consumption of water is needed in the mining process (International Atomic Energy Agency [IAEA], 2005). However, the strong acids used to dissolve the ore body commonly dissolve metals in the host rock as well.
An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining ; they are then refined (often …

Earlier bulletins summarized the mining and milling of ores of the principal metallic minerals,4 or specific problems 5 in the exploitation of metal mines. The purpose of this bulletin is to consolidate and analyze the information contained in earlier reports on mining methods, practices, and costs.
After recovery, the metals may be still further refined (purified) or alloyed with other metals, as in a copper refinery or steel mill. Mining, processing, and refining are thus successive steps in the utilization of an ore deposit to yield a metal. William Andrew Hustrulid
Mining and Processing Metal Ores The process of separating metals from their ores is called extraction. Based on the composition of the deposit, the price of extracting the metal changes, so the value of extracting the metal must be weighed against the cost.
Metal and Iron Ore Mining The Iron Age began around 1200 BC, ending the Bronze Age that preceded it and paving the way to man's mastery of metal. Individuals during this period began extracting iron ore to forge tools and weapons.
