Ore - Wikipedia
Ore bodies are formed by a variety of geological processes generally referred to as ore genesis and can be classified based on their deposit type. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. [4]
CHAPTER 9: ORE DEPOSIT GEOLOGY - SGU
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 bodies are divided into reserves and resources.
Ore Body - an overview | ScienceDirect Topics
Generally, an ore body is an accumulation of a solid and fairly continuous mass of ore with gangue, distinctly distinguishable by form and character from the enclosing host rocks. An ore deposit might include single or several ore bodies.
ORE GEOLOGY – Environmental geology - INFLIBNET Centre
As we understand by now that an orebody is a mixture of valuable minerals and waste rock. Each orebody, which has a definite size and shape, is a mass that contains enough valuable mineral to be mined and processed at profit.

Ore Body, Shapes and Occurrence of | SpringerLink
2022年12月27日 · Ore bodies are geological bodies that occur in the crust with sufficient ores and mining value. The ore body has a certain shape, occurrence, and scale. The rocks without economic significance around the ore body are the surrounding rocks.
Orebody - Mining Fundamentals
Metal ore bodies are generally sulfides, oxides, silicates or, in some cases, native metals. Ore bodies are formed by geological processes called ore genesis. Ore genesis processes may be one of these three types: magmatic, hydrothermal, or metamorphic. In some cases, surficial processes, executed by the environment, also result in ore genesis.

2019年12月15日 · Ore bodies are naturally occurring phenomena with little consistency and similarity between different locations and ore types. Even within a single ore body, variations in rock type, ore grade, chemistry, mineralogy, alteration, and deportment of pay metals and deleterious elements exist both vertically and laterally, thus causing issues in ore ...
Ore, Composition and Classification of | SpringerLink
2022年12月27日 · Ore is a mineral aggregate mined from an ore body from which useful components (elements, compounds, or minerals) can be extracted under existing technical and economic conditions. Ores are formed in various metallogenesis processes. Ores formed under different metallogenesis or at different stages of metallogenesis have different characteristics.
Ore Body Modelling- Concepts and Techniques - Academia.edu
Before estimating economically mineable ore reserves of a deposit, the ore body configuration must first be defined. After sampling the concentration of components at a set of sample points, extrapolation and geostatistical interpolation to the nodes of a three-dimensional model of the ore body is performed.
