There are 3000 various types of Minerals and based on their composition, they can be classified into metallic and non-metallic minerals. Metallic minerals contain metal in the raw form. Metals are hard substances that conduct heat and electricity and have a characteristic lustre or shine. Iron ore, bauxite, manganese ore are some examples.


The Patricia ore deposit represents an unusual example of economic Zn–Pb–Ag mineralization at the northernmost end of the Late Eocene–Oligocene metallogenic belt in Chile. It is hosted by volcano-sedimentary units, which are typically tuffaceous and andesitic breccias. The ore body consists of a set of subvertical E-W vein systems developed under a sinistral strike-slip regime that ...

Chile has a high level of specialization in Halogens (102), Copper Ore (78.3), Molybdenum Ore (72.3), Pitted Fruits (67.6), and Nitrites and Nitrates (60.9). Specialization is measured using RCA, an index that takes the ratio between Chile observed and expected exports in each product.


cate that the deep melt reservoirs from which both the shallow intrusions and the ore fluids were derived may be compositionally calc-alkaline, alkali-calcic, or alkaline (Seedorff and others, 2005). Representative examples of the rock types found in porphyry copper deposits are listed in table 1. Relations to Sedimentary Rocks

According to the International Energy Agency, average copper ore grades in Chile have declined by 30% in the last 15 years. Since Chile's mines produce more than one-fourth of the world's copper, these falling ore grades could be a cause for concern—especially with a deficit looming over the market for refined copper.

Iron ore | BHP

What is iron ore? Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, bright yellow, or deep purple to rusty red.

It was named after Waldemar Lindgren who established that most metallic ore deposits are emplaced by hot solutions from below, and first found in that greatest of holes in the ground, Chuquicamata Copper Mine, Chile. Miniature size specimen about 1½" tall. (Copper molybdate Cu 3 (MoO 4) 2 (OH) 2). 2731


Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.


This leaching process concentrates these minerals as ore that can be mined. Of the 15 major types of mineral deposits in the Western Hemisphere formed by action of ground water, 13 occur in deserts.

Open-pit mining - Wikipedia

Open-pit mining, also known as open-cast or open-cut mining and in larger contexts mega-mining, is a surface mining technique of extracting rock or minerals from the earth from an open-air pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially ...


Carlin-type gold deposits in Nevada, USA, although characterized by aqueous-carbonic fluids (e.g., Cline et al., 2005), are notable for their lower ore-fluid CO 2 content relative to orogenic gold deposits and their restriction to non-metamorphic sedimentary-rock environments along the North American craton margin.
