Of Metallic Ore Deposits

metallic ore deposits kinds of metallic ore deposits. Ore Wikipedia, the free encyclopedia An ore deposit is one occurrence of a particular ore . Metal Madness: The geology of metallic mineral .

Types of Deposits:

Many ore deposits have been enriched in terms of their metal content where supergene (downward moving) fluids have dissolved metallic minerals from the nearsurface parts and redeposited these in the lower parts by replacement of other (gangue) minerals. At higher temperatures the degree of replacement of preexisting minerals increases, till in extreme cases, there is complete replacement.

Copper Ore Types: Sulfides vs. Oxides | Investing News Network

There are two main types of copper ore of interest: copper oxide ores and copper sulfide ores. Both ore types can be economically mined, though they are processed in different ways.

Gold and silver are obtained from a variety of ores, in some of which the gold predominates, in others silver is the primary value, while in still a third class these two metals may be mixed with the base metals, such as lead, copper, zinc, and iron.

Types of minerals | Minerals and Mineral Resources

Ores. Minerals containing some metal are often labeled as ore minerals. The most common minerals in this group are various sulfides, oxides and native elements. Typical examples are pyrite, galena, sphalerite, magnetite, haematite, uraninite or native gold, silver and copper. Gems and precious stones. There is no solid definition of precious stone or gem.

Currently, California has active mines for gold and silver, and also for nonmetal minerals like sand and gravel, which are used for construction. Underground Mining . Underground mining is used for ores that are deep in Earth's surface. For deep ore deposits, it can be too expensive to remove all of the rocks above the ore.

Geology of Gold Mineralization How Gold Deposits are Formed

The Geology Of Gold Gold is relatively scarce in the earth, but it occurs in many different kinds of rocks and in many different geological environments. Though scarce, gold is concentrated by geologic processes to form commercial deposits of two principal types: lode (primary) deposits and placer (secondary) deposits.

Ore deposits are metallic minerals in sufficient volume and concentration to be extracted economically. They are generally formed through one of three geological processes. Magmatic ore deposits are concentrated within a body of igneous rock.
