>>MoreTypes of Ore. Ore is rock that contains economic amounts of a particular element, e.g. gold ore, iron ore, molybdenum ore, or praseodimium ore. In contrast, rock that is not judged to contain economic quantities of an element is egorized as waste rock. The metals in ore can occur in many different minerals (compounds)

As the ore was actually a nickel minerals most commercial mining is focused on two types of ore deposits Sulphide type nickel deposits are usually, although not always, found.
>>MoreAs the name suggests, openpit mining creates a big pit from which the ore is mined. Figure 3.27 shows an openpit 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

>>MoreSep 25, 2015 Geological ore deposits are of many different types and occur in all geological environments. The main types of geological ore deposits of importance can be divided into: metallic deposits . Coal is a general name given to stratified accumulations of carbonaceous material derived from vegetation.

>>MoreMekanism has a "Dictionary" item that shows the ore dictionary name for any item you rightclick. I would definitely recommend building it. Wildcards also work and get literally every ore registered in the ore dictionary. For names that are too long, you can type it most of the way and put a * at the very end.
>>MoreAn 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.

>>MoreTypes of ores. Ores or metallic rocks and minerals are classified into two egories 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 lowgrade gold, they will use openpit mining, while in highgrade gold
>>MoreOpenPit. As the name suggests, open pit mining involves mining minerals or ore that can be found near the surface layer of the site. That being said, some quarries can be over 1000 meters deep. This form of mining doesn't require tunnelling into the earth and is a simple method of mining that yields high production rates.
>>MoreSep 5, 2017 Often used to help find underground resources, as the name suggests, mining surveys are used to scope out potential mining loions.
