Ore - Wikipedia
Ore is natural rock or sediment that contains one or more valuable minerals, typically metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals.
Mineral Ore Deposits: Meaning, Origin and Types | …
An ore deposit may be either of igneous or of sedimentary origin. Some deposits are related to metamorphic processes and are as such classified as deposits of metamorphic origin. Within these three broad modes of origin, a mineral deposit of economic value might have originated due to set of simple or complex processes. Types of Ore Deposits: 1.

Ore Deposit - an overview | ScienceDirect Topics
Magmatic ore deposits may be defined as rocks of igneous origin (see IGNEOUS PROCESSES), which can profitably be mined for their constituent stone elements.For example, the worth of annual global production from magmatic ore deposits exceeded $10 billion in 2001, and dominates or contributes significantly to world supplies of elements representing more than a third of the periodic table.

Classification of ore deposits - SlideShare
Classification of ore deposits 1. CONTENTS ... However, genetic classifications are very dangerous, as they assume that we know the origin of the ore deposit, which, in many cases, we don’t! They are also subject to change as scientists revise their models for the genesis of an ore deposit.
Ore genesis - Wikipedia
Often ore deposits are classified after examples of their type, for instance Broken Hill type lead-zinc-silver deposits or Carlin–type gold deposits. Genesis of common ores [ edit ] As they require the conjunction of specific environmental conditions to form, particular mineral deposit types tend to occupy specific geodynamic niches, [5] therefore, this page has been organised by metal ...
