Subaru's EJ257 was a turbocharged, 2.5-litre horizontally-opposed (or 'boxer') four-cylinder engine. For Australia, the EJ257 engine was introduced in the Subaru GD Impreza WRX STi in 2005 and subsequently powered the GE/GH Impreza WRX STi and V1 WRX.Effectively replacing the 2.0-litre EJ207 engine, the EJ257 engine was a member of Subaru’s Phase II EJ engine
Subaru's EJ20K was a turbocharged, 2.0-litre horizontally-opposed (or 'boxer') four-cylinder petrol engine. In Australia, the EJ20K engine powered the Subaru GC/GM Impreza WRX from November 1996 (for the 1997 ‘model year’ or MY97) to 1998. For the Subaru GC/GM Impreza WRX, key features of the EJ20K engine included:

Industrial resources (minerals) are geological materials which are mined for their commercial value, which are not fuel (fuel minerals or mineral fuels) and are not sources of metals (metallic minerals) but are used in the industries based on their physical and/or chemical properties. They are used in their natural state or after beneficiation either as raw materials or as additives in a
Caliche (/ k ə ˈ l iː tʃ iː /) is a sedimentary rock, a hardened natural cement of calcium carbonate that binds other materials—such as gravel, sand, clay, and silt. It occurs worldwide, in aridisol and mollisol soil orders—generally in arid or semiarid regions, including in central and western Australia, in the Kalahari Desert, in the High Plains of the western United States, in the
Jan 01, 2015 Limestone was usually chosen as a cheap additive for roasting of lepidolite.43., 54., 55., 56. In a process patented by Mazza et al., 43 a mixture of lepidolite, limestone, and water was fed to roasting at 900 C for 2 h. The calcine was thereafter immediately quenched to release lithium, resulting in a lithium extraction of ∼80%

The raw materials used to produce pig iron in a blast furnace are iron ore, coke, sinter, and limestone. Iron ores are mainly iron oxides and include magnetite, hematite, limonite, and many other rocks. The iron content of these ores ranges from 70% down to 20% or less
Limestone is used as a fluxing agent and to get strength to the pellet by heat hardening. Coke dust is used as a compensatory fuel and to improve physical strength of the pellets by uniform firing of each pellet up to the core. Both limestone and coke are ground in a definite lime to coke ratio in a ball mill by dry grinding process
Mar 15, 2021 Clay minerals such as kaolinite, smectite, chlorite, micas are main components of raw materials of clay and formed in presence of water. A large number of clays used to form the different structure which completely depends on their mining source. They are known as hydrous phyllosilicate having silica, alumina and water with variable amount of inorganic ions like
Feldspar Group. Ca-rich end member of the Albite-Anorthite Series. High- and low-temperature structural modifications exist
