Igneous textures are rock textures of igneous rocks used by geologists in identifying the origin of rocks and for the classification of rocks. Phaneritic texture is one of the six main textures of rocks. Phaneritic rocks are intrusive igneous rocks with coarse crystals of equal size.
Pig iron is an intermediate product obtained during smelting of iron ore using high-carbon fuel such as coke, charcoal or anthracite. In addition to iron, pig iron consists of varying amounts of phosphorus, sulfur, manganese, silicon and carbon.
Pitchblende is an amorphous form of the crystalline uranium oxide mineral known as uraninite.
A polishing pond is the last in the series of settling ponds through which the mill effluent is made to flow through. The mill effluent is made to flow through a series of waste water treatment ponds before being discharged into the natural environment.
Placer deposit or placer is a natural accumulation of heavy valuable minerals which are formed by the gravitational effect during sedimentary processes. Placer mining is critical for gold extraction and one of the main mining methods used in several gold rushes including the California Gold Rush.
This article explores how this method can be utilized to characterise the phases existing in an igneous rock.
Block caving is a gravity-based underground mining method that involves breaking up the rock mass located at depth into pieces. This method is particularly suitable for low-grade minerals or with disseminated mineralization.
Topaz is a silicate mineral made of fluorine and aluminum. It was named after Topasos Island in the Red Sea from where it was first discovered.
AZoMining talks to Prof. Alexander Khavkin about how newly developed nanotechnology could help to access technologically hard-to-recover reserves and also provide benefits and cost reductions in currently active reserves.
