mining of minerals and ore

9 ore deposits and economic minerals mineralogy

At first glance, sustainability and mineral resource development appear to be in conflict. Mining depletes finite resources and in a strict sense, therefore, is inherently unsustainable. For instance, there is only a finite amount of copper in the earths crust, and each unit of copper extracted ... Many different mineral commodities are important to modern society. However, when mineralogists think about mining, they are generally thinking of ore minerals that are the sources of important metals, or of minerals that have specific, highly valued properties (e.g., asbestos, micas, potash, and gems of all sorts).That is what we will focus on in most of the rest of this chapter.

finding and mining ores read earth science ck12

The more concentrated an ore mineral, the more valuable the mineral deposit. A mineral deposit that is sufficiently rich to be worked at a profit is called an ore deposit, and in an ore deposit the assemblage of ore minerals plus gangue is called the ore. Dec 13, 2021 Ores are generally divided into metallic ores and non-metallic ores. Mineral ores are aggregates of minerals from which useful components can be extracted or which possess certain properties that can be exploited. Ore composition Ore is generally composed of ore minerals and gangue minerals.

ore, a natural aggregation of one or more minerals that can be mined, processed, and sold at a profit. An older definition restricted usage of the word ore to metallic mineral deposits, but the term has expanded in some instances to include nonmetallics. Although more than 2,800 mineral species Surface mining allows extraction of ores that are close to Earths surface. Overlying rock is blasted and the rock that contains the valuable minerals is placed in a truck and taken to a refinery. As pictured in Figure below, surface mining includes open-pit mining and mountaintop removal. Other methods of surface mining include strip mining ...

chapter 1 an introduction to minerals ore and exploration

Ore is removed from the crust by mining, either on the surface (open pit mining) or underground (shaft mining or room and pillar mining). Some minerals can be used in their natural form, for example sand in the building industry, phosphate rock for fertilisers and diamonds in jewellery. Trying to find ore is called mineral exploration, or just exploration. Exploration is done in many steps, and it often takes several years or even decades to find and define an ore body that can be potentially mined. Few exploration projects lead to opening of a mine. Exploration
