9 Ore Deposits and Economic Minerals Mineralogy

9.1.3 Mineral Deposits, Ore Deposits, and Mining. A mineral deposit is a place in Earth’s crust where geologic processes have concentrated one or more minerals at greater abundance than in the average crust. 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

Mineral deposit Britannica

All ore deposits are mineral deposits, but the reverse is not true. Ore deposit is an economic term, while mineral deposit is a geologic term. Whether a given mineral deposit is also an ore deposit depends on many factors other than the level of concentration and the size of the deposit; all factors that affect the mining, processing, and transporting of the ore must be considered as well.

Mining Massachusetts Institute of Technology

Mining is the extraction of minerals and elements of economic interest from the earth's surface. As the demand for natural resources increases, the amount of material in mineral deposits decreases. An increase in price of these materials allows companies to continue to profit from mining deposits with lower ore grades.

ME551/GEO551 INTRODUCTION TO GEOLOGY OF

An ore deposit is a well-defined mineral deposit that has been tested and found to be of sufficient size, grade, and accessibility to be extracted (i.e. mined) and processed at a profit at a specific time. Thus, the size and grade of an ore deposit changes as the economic conditions change. Ore refers to industrial minerals as well as metals.

GY 111 Lecture Note Series Economic Geology

Mining geologists call the non-economic stuff gangue and need to consider it’s presence when determining if an economic deposit is worth mining or not. Ultimately it all comes down to how much money you can make. If it’s a lot (i.e., the ore deposit contains a lot of reserves), the extra cost of disposing of the gangue is not an issue.

Mining Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef, or placer deposit.These deposits form a mineralized commodity that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Introduction to Mineral Deposit Models USGS

A "mineral deposit" is a mineral occurrence of sufficient size and grade that it might, under the most favorable of circumstances, be considered to have economic potential. An "ore deposit" is a mineral deposit that has been tested and is known to be of sufficient size, grade, and accessibility to be producible to yield a profit.

Understanding Iron Ores and Mining of Iron Ore IspatGuru

Apr 03, 2015 Mining (extraction), beneficiation, and processing of iron ore produces iron and steel. Mining is defined as removing ore material from a deposit and encompasses all activities prior to beneficiation. High grade iron ores (iron content greater than 62 %) are simply crushed, screened and shipped directly to the iron making unit (e.g. blast furnace).

Geology: What is a Mineral Deposit? — Mining Focus

An "ore deposit" is a mineral deposit which has high enough grades of metal that makes it economic to mine. Essentially this means that per tonne of rock containing the desired minerals, the costs of removing the minerals from the rock and separating the metal from the minerals are lower than the value of metal per tonne of rock.
