Laterite Wikipedia

Laterite is both a soil and a rock type rich in iron and aluminum and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. They develop by intensive and prolonged weathering of the underlying parent rock.Tropical weathering (laterization) is a prolonged process of chemical weathering which

Nickel Simple English Wikipedia, the free encyclopedia

The isotopes of nickel range in atomic weight from 48 Ni to 78 Ni. Nickel that is found in nature is made up of five stable isotopes; 58 Ni, 60 Ni, 61 Ni, 62 Ni and 64 Ni.. At least 26 radioisotopes of nickel have been found. The most stable radioisotope is 59 Ni which has a half-life of 76,000 years. Nickel also has one meta state.. History. Nickel was found when an ore that looked like

Nickel Laterite Ore Deposits: Weathered Serpentinites

Nickel laterite ores account for over 60% of global nickel supply. They are the product of intensive deep weathering of serpentinites under humid tropical conditions. Nickel is concentrated to over 1.0 wt% and is hosted in a variety of secondary oxides, hydrous Mg silicates and smectites.

Ore Wikipedia

Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit.Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.

Ultramafic rock Wikipedia

Weathered ultramafic rocks may form lateritic nickel ore deposits. Possible detection on Io. Ultramafic lava may have been detected on Io, a moon of Jupiter, because heat-mapping of Io's surface found ultra-hot areas with temperatures in excess of 1,200 °C (2,190 °F). The lava immediately below these hots spots is probably about 200 °C (360

Nickel mining in Indonesia Wikipedia

Ore. The most important Indonesian nickel ores are lateritic, primarily located in Sulawesi and Halmahera with mining operations centered at ultramafic rock outcrops. While the lateritic nickel ores are more difficult to smelt compared to nickel sulfide ores, it is more extractable due to its location on the surface. In 2019, it was reported that Indonesia possessed proven reserves of 698
