Ore deposits and ore minerals fall into several main commodity groups: metallic and semimetallic elements, nonmetallic elements, gems, construction and manufacturing materials, fertilizer and chemical minerals, and energy resources (table below).

An ore deposit is an economically significant accumulation of minerals within a host rock. [9] This is distinct from a mineral resource in that it is a mineral deposit occurring in high enough concentration to be economically viable. [4] An ore deposit is …

2022年8月28日 · An ore deposit is a mineral deposit that can be produced to make a profit. Thus, all ore deposits are mineral deposits, but the reverse is not true. Many factors control the profitability of an ore deposit. We call the amount of known ore in a deposit the reserves.

2022年8月28日 · Most metallic ore minerals are native elements, sulfides, sulfosalts, oxides, or hydroxides. Ore deposits are highly variable in nature and origin. The most important kinds of ore deposits are magmatic, hydrothermal, and sedimentary.

An ore deposit, in its simplest terms, is a portion of the Earth’s crust from which some industrial raw material can be extracted at a profit. As such, its characteristics are as much economic as geochemical.

2023年11月2日 · Ore deposits form when the metals come out of the solution again and crystallize as ore minerals. Crystallization often happens when the hydrothermal fluid flows into colder rocks and cools—think of rock candy growing from a sugar solution.

The ore deposit has a typical, well-defined shape that resembles the cap of a mushroom. Its “stem” is the volcanic vent, which has solidified into porphyry and then cracked to form numerous veins through which the fluid pushed its way upwards.

An ore deposit consists of one or more ore bodies. An ore body is a mass of rock that contain ore and from which a commodity of value will be extracted. Not all ore within an ore body will be extracted.

Ore deposits are rock volumes containing selected elements in sufficient concentration and quantity that they can be extracted economically. Except for Fe and Al, all technically important metals and other elements are scarce, in total constituting less than ~1% of the Earth's crust.

2025年1月14日 · An ore deposit, in its simplest terms, is a portion of the Earth’s crust from which some industrial raw material can be extracted at a profit. As such, its characteristics are as much economic as geochemical.
