Lithium is an element valuable for the production of glass, aluminum products, and batteries. It is mined from ores of petalite (LiAl(Si2O 5) 2, lepidolite K(Li,Al) 3 (Al,Si,Rb) 4 O 10 (F,OH) 2, spodumene LiAl(SiO 3) 2 and also subsurface brines. Australia and Chile are the world's largest producers of lithium.

Underground Mining Methods and Equipment

drilling and blasting are usually employed when the ore is too hard for cutting. A drifting jumbo equipped with one or multiple rock drills is employed for penetrating horizontal blastholes and used for driving horizontal dr ifts and inclined ramp s as well as production by crosscutting in room-and-pillar mining and cut-and-fill stoping.

mining engineering: Conveyors and Feeders

Hard rock mine belt conveyors normally require the ore to be crushed before it is conveyed or at least broken enough to pass through a grizzly opening. Run-of-mine (ROM) material is not normally conveyed except for short level runs. The finer the ore is crushed, the longer the belt life, the more reliable the system, and the lower the operating ...

Iron Ore Facts -

Iron ore is rock which metallic iron can be extracted from. Iron ore is the most common element in the world and makes up close to 5% of the Earth's crust. This makes it one of the most abundant rock elements. Iron ore that contains a high quality of hematite or magnetite are known as "natural ore" and they can be entered directly into blast furnaces that produce iron.

Ore Minerals : What are Ore Minerals? - Geology Page

An ore is a natural occurrence of rock or sediment which contains enough minerals with economically important elements, typically metals, that can be extracted from the deposit economically. The ores are extracted by mining for a profit from the earth; they are then refined (often by smelting) in order to extract the valuable elements.

Block caving: A new mining method arises |

Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.

SURFACE MINING – Mining Engineering Site

Rock-is any naturally formed aggregate of one or more types of mineral particles. Economic differences in the nature of mineral deposits are evident in the following terms: Ore-is a mineral deposit that has sufficient utility and value to be mined at a profit. Gangue-is the valueless mineral particles within an ore deposit that must be discarded.

Hard Rock Mining vs. Placer Gold Mining

Hard rock, or "Lode" gold is still contained within ore, and various methods are used to extract the metal from the rock that surrounds it. Placer gold on the other hand occurs when natural erosion has released the gold from its host material and the gold is now a separate piece, whether that be a small speck of gold dust or a large gold ...
