mining type of extracting ores minerals

What type of mining is used to extract veins of ore deposits from the ground? minerals occur at veins and lodes,sedimentary ore deposits,alluvial or placer depositsand by weathering

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

The method used depends on the type of mineral resource that is mined, its location at or beneath the surface, and whether the resource is worth enough money to justify extracting it Each mining method also has varying degrees of impact on the surrounding landscape and environment Learn More Metal Mining and the Environment Booklet

About 80 of all copper extracted comes from sulphide ores A typical ore contains only 0 5 to 2 0 copper It is a measure of the value of copper that it is worth extracting it from such small concentrations The ore is a mixture of minerals and rock called gangue The most common copper minerals are:

Ore minerals are the minerals within ores that contain the metal Ores occur as large bodies of rock called ore deposits, which are metal bearing mineral deposits Types of Minerals Minerals can be divided into: Metallic and Non metallic minerals Metallic minerals are further divided into Ferrous and non ferrous minerals

1 Introduction to the extraction of metals What methods can be used in extracting metals from mineral ores? The Earth's crust contains many different rocks Rocks are a mixture of minerals and from some we can make useful substances A mineral can be a solid metallic or nonmetallic element or a compound found naturally in the Earth's crust

Leaching is a chemical process in mining for extracting valuable minerals from ore Leaching also takes place in nature, where the rocks are dissolved by water Post leaching, the rocks are left with a smaller proportion of minerals than they originally contained The leaching process in mining is

Although the character of waste rock varies with the type of ore, many waste rocks contain sulfide minerals associated with metals, such as lead, zinc, copper, silver, or cadmium An important sulfide mineral common in waste rock is pyrite, iron sulfide

Feb 16, 2015 Ores are types of rocks having more minerals with important elements including metals that can be economically extracted from the rocks In fact, ores are extracted through mining the process of extracting valuable minerals or metals from the earth by miners working in mining industries or metallurgical industries

The barren rock, or gangue has to be separated from the sulfide minerals in order to smelt the metallic copper from the ore By far the greatest proportion of copper is extracted from the sulfides of copper, iron and sometimes other metals Such ores originate from sulfur bearing volcanic magmas, which have separated into metal sulfides and siliceous melts

Iron ores are rocks and mineral deposits from which clanging iron can be reasonably extracted Iron ore mining is classified into two categories manual mining and mechanized mining methods Haematite and magnetite are the most commonly found iron ore minerals Deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the

Mineral processing: Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue It is the first process that most ores undergo after mining in order to provide a more concentrated material for

Mining is the process of mineral extraction from an ore or rock seam The minerals can range from precious metals and iron to gemstones and quartz In ancient times, miners recognized a mineral rock formation from its outcrop at the surface Modern mining technology uses geophysical techniques that involve measuring

Geologists and Mining Engineers work tirelessly in determining the most efficient and cost effective method of extracting a deposit of minerals or ore and even before this, much work is made in determining whether a site is rich with material or not What are the different types of mining and how do they differ? Description This article

Jul 23, 2018 The process of extracting metal ores buried deep underground is called Mining The metal ores are found in the earths crust in varying abundance The extraction of metals from ores is what allows us to use the minerals in the ground! The ores are very different from the finished metals that we see in buildings and bridges

An ore is a natural 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 at a profit from the earth through mining they are then refined often via smelting to extract the valuable element, or elements

Reading: Mining and Mineral Use An ore is a rock that contains minerals with useful elements Aluminum in bauxite ore figure 1 is extracted from the ground and refined to be used in aluminum foil and many other products The cost of creating a product from a mineral depends on how abundant the mineral is and how much the extraction and
