Nickel Mining In Indonesia
Nickel mining in Indonesia began with small-scale exploratory mining operations during the Dutch East Indies era and began to expand in the 1960s. Most of Indonesia's proven nickel reserves are located in the islands of Sulawesi and Halmahera, and the country has the largest annual production and reserves of nickel in the world. History Nickel ore was first prospected in Indonesia (then known as Dutch East Indies) in 1901 in the Verbeek Mountains of Sulawesi by a Dutch mineralogist, with further discoveries in what is today Kolaka Regency in 1909. A Canadian geologist from Inco further prospected the existing deposits and in 1934 exploration efforts from a Dutch mining firm began. Initial production began in 1936 to 1941, with operations being expanded during the Japanese occupation of the Dutch East Indies. After the independence of Indonesia, the American Freeport Sulphur Company attempted to establish operations, but failed due to security concerns. NV Perto, a local company, too ...

Dutch East Indies
The Dutch East Indies, also known as the Netherlands East Indies ( nl, Nederlands(ch)-Indië; ), was a Dutch colony consisting of what is now Indonesia. It was formed from the nationalised trading posts of the Dutch East India Company, which came under the administration of the Dutch government in 1800. During the 19th century, the Dutch possessions and hegemony expanded, reaching the greatest territorial extent in the early 20th century. The Dutch East Indies was one of the most valuable colonies under European rule, and contributed to Dutch global prominence in spice and cash crop trade in the 19th to early 20th centuries. The colonial social order was based on rigid racial and social structures with a Dutch elite living separate from but linked to their native subjects. The term ''Indonesia'' came into use for the geographical location after 1880. In the early 20th century, local intellectuals began developing the concept of Indonesia as a nation state, and set the stage ...

Southeast Sulawesi
Southeast Sulawesi ( id, Sulawesi Tenggara) is a province on the island of Sulawesi, forming the southeastern peninsula of that island, together with a number of substantial offshore islands such as Buton, Muna, Kabaena and Wawonii (formerly called Wowoni), together with many smaller islands. The capital is the city of Kendari, on the east coast of the peninsula. The province has no highway road connecting to the rest of the island, and the primary transportation link is a ferry across the Bone Gulf between Watampone (Bone) in South Sulawesi and the port of Kolaka in Southeast Sulawesi. History From the seventeenth century until the early twentieth century, the region was the site of the (Butung). Geography The two major mountain ranges in Southeast Sulawesi are the Tanggeasinua Range and the Mekongga Range. The major rivers are the Lalinda, the Lasolo, and the Sampara. Demographics The population of the province was 2,232,586 at the 2010 decennial census (1,120,225 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultramafic Rock
Ultramafic rocks (also referred to as ultrabasic rocks, although the terms are not wholly equivalent) are igneous and meta-igneous rocks with a very low silica content (less than 45%), generally >18% MgO, high FeO, low potassium, and are composed of usually greater than 90% mafic minerals (dark colored, high magnesium and iron content). The Earth's mantle is composed of ultramafic rocks. Ultrabasic is a more inclusive term that includes igneous rocks with low silica content that may not be extremely enriched in Fe and Mg, such as carbonatites and ultrapotassic igneous rocks. Intrusive ultramafic rocks Intrusive ultramafic rocks are often found in large, layered ultramafic intrusions where differentiated rock types often occur in layers. Such cumulate rock types do not represent the chemistry of the magma from which they crystallized. The ultramafic intrusives include the dunites, peridotites and pyroxenites. Other rare varieties include troctolite which has a greater percentag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lateritic Nickel Ore Deposits
Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining of nickel. Genesis and types of nickel laterites Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite, peridotite and komatiite and their serpentinized derivatives, serpentinite which consist largely of the magnesium silicate serpentine and contains approx. 0.3% nickel. This initial nickel content is strongly enriched in the course of lateritization. Two kinds of lateritic nickel ore have to be distinguished: limonite types and silicate types. Limonite type laterites (or oxide type) are highly enriched in iron due to very strong leaching of magnesium and silica. They consist largely of goethite and contain 1-2% nickel incorporated in goethite. Absence of the limonite zone in the ore deposits is due to erosion. ...

Weda Bay Industrial Park
The Weda Bay Industrial Park is a nickel mining and industrial park complex in Central Halmahera Regency, North Maluku, Indonesia. The Weda Bay Mine is now among the largest nickel mines in the world. History Nickel deposits were discovered in the Weda Bay area in Central Halmahera in 1996, and a joint venture between Canada-based Weda Bay Minerals and Antam (10%) was established in 1997. French mining group Eramet acquired the Canadian stake in 2006, and planned to develop the site, but due to low mineral prices the project was put on hold in 2013. In 2017, China's Tsingshan Group signed an agreement, giving it a 57% stake in Weda Bay Minerals, and giving Tsingshan the responsibility to develop mineral processing while Eramet retained its mining operations. Construction of the industrial park began in April 2018, with mining operations commencing in October 2019 and metallurgical production in April 2020. As of 2020, four nickel ferroalloy production lines are active in the in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
