Mineral Ore Deposits: Meaning, Origin and Types | Geology
Ore Deposit: Natural concentration of an ore mineral in a massive rock body is defined as an ore deposit. It may be of any shape and form but its size is of real importance. A small patch or layer of bauxite, say one meter thick and a kilometer long will not make an ore deposit.
Iron Ore: Sedimentary Rock - Pictures, Definition & More
Earth's most important iron ore deposits are found in sedimentary rocks. They formed from stone reactions that combined iron and oxygen in marine and fresh waters. The two most important minerals in these deposits are iron oxides: hematite (Fe2O3) and magnetite (Fe3O4).

Grade and tonnage distribution. Generally, as zircon is the most valuable component and a critical ore component, high-zircon sands are the most valuable. Thereafter, rutile, leucoxene and then ilmenite in terms of value given to the ore. As a generality, typically the valuable components of the THM concentrate rarely exceed 30%.
Different Types of Iron Ore - Mineral Processing & Metallurgy
Contact metamorphic deposits of magnetite are to be looked for at the contacts of igneous rocks of the intermediate kind (diorite, etc.), or the basic kind (diabase, etc.), with crystalline, limestone, dolomite, or limey shale. The ore bodies are usually irregular and not very large.

Types of Ore. Sedimentary ore deposits include banded iron formations, and gold, platinum, zinc, tin, and even diamond-containing ores that formed in sedimentary environments. Lastly, ores can form as a result of hydrothermal processes. These processes involve …
Ore genesis - Wikipedia
Ore genesis. Various theories of ore genesis explain how the various types of mineral deposits form within the Earth's crust. Ore-genesis theories vary depending on the mineral or commodity examined. Ore-genesis theories generally involve three components: source, transport or conduit, and trap.
INTRODUCTION TO MINING - Ciência Viva
Ore:a mineral deposit that has sufﬁcient utility and value to be mined at a proﬁt. Gangue:the valueless mineral particles within an ore deposit that must be discarded. Waste:the material associated with an ore deposit that must be mined to get at the ore and must then be discarded. Gangue is …
Ore Deposits - Geologia Economica I - Passei Direto
There are four basic geological requirements for any ore deposit to form (Figure 1): - i) a source for the ore components (metals and ligands); ii) a mechanism that either transports these components to the ore deposit site and allows the appropriate concentration or removes non- ore components to allow residual concentration; iii) a ...

Metallic Deposits - CliffsNotes Study Guides
Metallic Deposits Metals occur in all kinds of rocks but usually in concentrations that are too low to be mined. Metallic ore deposits , however, are relatively rare concentrations of metal‐bearing minerals (usually sulfides) that contain enough metal to be profitably mined.

Sources of ore fluid components in IOCG deposits ...
Genetic models need to consider a number of different ore fluid components that may not all have the same source in an individual ore system, and also that economic IOCG deposits may include examples in which key components (especially copper) had different sources.
How to Identify Platinum in Ore Deposits | Sciencing
Sources for ore rocks often exist in areas of stream flow in the form of placer deposits. In South America, pre-Columbian civilizations found platinum intermixed with gold in river deposits. The largest platinum deposits reside in Russia, South Africa and Zimbabwe, with smaller deposits …

MINERALOGY AND PETROLOGY OF SKARN DEPOSITS
They are closely associated genetically and spatially with other types of ore deposits, such as porphyry copper and greisen deposits. 4. Their intimate admixture of iron·rich skarn minerals and ore minerals implies that skarns may provide natural examples of the laboratory processes of sulfidation and oxidation.
