What are the important ores of nickel?

The bulk of the nickel mined comes from two types of ore deposits:

• laterites where the principal ore minerals are nickeliferous limonite [(Fe,Ni)O(OH)] and garnierite (a hydrous nickel silicate), or.
• magmatic sulfide deposits where the principal ore mineral is pentlandite [(Ni,Fe)9S8].

What is the common ore of platinum?

The main ore minerals of platinum ores are pyrrhotite, chal-copyrite, pentlandite, and cubanite. The main platinum group metals in copper-nickel ores are platinum and palladium, which occurs in greater quantities (Pd:Pt ≧ 3:1).

What is ore formula?

Limonite FeO(OH) · n(H2O) (Brown hematite, brown iron ore (also used for Goethite); lemon rock, yellow iron ore (if its orange / yellow)….Iron Ores.

What are 2 examples of ores?

An ore is a naturally occurring compound (mineral) from which a metal and even some non-metals may be extracted economically. Examples of ore are bauxite, haematite and galena.

What is the chemical formula for nickel?

Ni+2
Nickel (II) ion

What is nickel ore used for?

Nickel has outstanding physical and chemical properties, which make it essential in hundreds of thousands of products. Its biggest use is in alloying – particularly with chromium and other metals to produce stainless and heat-resisting steels.

Is platinum an ore?

Platinum is also mined as an ore . Platinum ores such as sperrylite and cooperite may be mined when they are found in quantities that make extraction economically feasible. In other situations, platinum is obtained as a by-product when ores of other metals, such as copper and nickel, are refined.

Where is platinum ore found?

The majority (about 80 percent) of platinum is mined in South Africa. Approximately 10 percent is mined in Russia, and the rest is found in North and South America, according to the U.S. Geological Survey.

What are the important minerals and ores?

Ores are those minerals from which metal are extracted conveniently and profitably. These ores contain good percentage of metal….Shakeel Anwar.

What are the ores of silver?

Silver is found in lead, zinc, gold and copper ore deposits. The most important ore mineral of silver is argentite (Ag2S, silver sulfide). Silver is commonly extracted from ore by smelting or chemical leaching.

What are the 5 ores?

List of Ores

What is the importance of ore?

Ore is a deposit in Earth’s crust of one or more valuable minerals. The most valuable ore deposits contain metals crucial to industry and trade, like copper, gold, and iron. Copper ore is mined for a variety of industrial uses. Copper, an excellent conductor of electricity, is used as electrical wire.

What metals are found in copper-nickel ores?

The main platinum group metals in copper-nickel ores are platinum and palladium, which occurs in greater quantities (Pd:Pt ≧ 3:1). The contents in ores of the remaining platinum group metals (rhodium, iridium, ruthenium, and osmium) are tens and hundreds of times less than those of palladium and platinum.

What are the main ores of platinum?

The main ore minerals of platinum ores are pyrrhotite, chal-copyrite, pentlandite, and cubanite. The main platinum group metals in copper-nickel ores are platinum and palladium, which occurs in greater quantities (Pd:Pt ≧ 3:1). The contents in ores of the remaining platinum group metals (rhodium, iridium, ruthenium,…

What is the difference between primary ore and ore minerals?

Phosphorus – Main ore minerals are in the apatite group of minerals (hydroxylapatite, fluorapatite, chlorapatite). Platinum group (Platinum, Osmium, Rhodium, Ruthenium, Palladium) – The primary ores are the native elements or alloys of the various elements or arsenides such as sperrylite.

What is the abundance of nickel in the Earth’s crust?

This chapter discusses the terrestrial abundance and distribution of nickel, palladium, and platinum. Nickel is the 7th most abundant transition metal and the 22nd most abundant element in the earth’s crust. Laterites and sulfides are the two commercially important ores of nickel.
