Ore - WikipediaAn ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.miners names for types of ore,Types of ores | CatapaTypes of ores. Ores or metallic rocks and minerals are classified into two categories depending on the amount of minerals per ton of rock, and the value of the mineral. . The grade determines the which mining technique is profitable; in the case of low-grade gold, they will use open-pit mining, while in high-grade gold.
Types of mining - StraterraOpen cast mining. Opencast mine. Essentially, overburden is removed, the exposed ore is recovered, and the pit is filled, progressively, by the next tranche of overburden. The ratio of overburden to ore may be 10:1, but can vary widely. The working footprint of an opencast mine like Macraes in Otago would typically be up to.miners names for types of ore,High School Earth Science/Mining and Using Minerals - Wikibooks .As the name suggests, open-pit mining creates a big pit from which the ore is mined. Figure 3.27 shows an open-pit diamond mine in Russia. The size of the pit grows until it is no longer profitable to mine the remaining ore. Strip mines are similar to pit mines, but the ore is removed in large strips. A quarry is a type of.John Frank
