Copper-Nickel ores - Danafloat

Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails. Pentlandite and iron sulphides are depressed by raising the pH up to 12 with lime and a small amount of sodium cyanide.

Nickel - Wikipedia

Nickel is a chemical element with the symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel belongs to the transition metals and is hard and ductile.Pure nickel, powdered to maximize the reactive surface area, shows a significant chemical activity, but larger pieces are slow to react with air under standard conditions because an oxide layer

This is com-monly carried out by magnetic separation, Sotation, or a combinationof both after the ore is comminuted to below 200 m in size. The enrichment depends upon the degree of rejection of the other sulRde and non-sulRde gangue. The maximum grade

cobalt processing | Uses, Supply, & Facts | Britannica

Nearly all cobalt is found associated with ores of copper, nickel, or copper-nickel. In the copper-cobalt ore bodies of central Africa and Russia, cobalt occurs as sulfides (carrollite, linnaeite, or siegenite), the oxide minerals heterogenite (hydrated cobalt oxide) and asbolite (a mixture of manganese and cobalt oxides), and the carbonate

Extraction of Nickel from Garnierite Laterite Ore Using

In this study, segregation roasting and magnetic separation are used to extract nickel from a garnierite laterite ore. The garnierite laterite ore containing 0.72% Ni, 0.029% Co, 8.65% Fe, 29.66% MgO, and 37.86% SiO2 was collected in the Mojiang area of China. Garnierite was the Ni-bearing mineral; the other main minerals were potash feldspar, forsterite, tremolite, halloysite, quartz, and

How is Nickel Mined - Want to Know it

As nickel is commonly found with other metals, especially iron, it is mined as an ore that needs to be separated and refined to produce nickel. Nickel is often extracted from its ore by roasting at high temperatures. In some cases this is enough to separate the nickel in other cases strong chemicals are used to separate the ore.

CARRIAGE OF NICKEL ORE AND IRON ORE FINES : Detailed Bulletin

6/1/  · Nickel ore is mined largely in Indonesia and the Philippines. Very little processing takes place when the ore is mined: it is usually dug up, sorted for size, stored in stockpiles and then shipped. Different mining methods are used in different areas, which can lead to variations in the physical consistency and moisture content of the cargo.

Gangue - Wikipedia

In mining, gangue (/ ɡ æ ŋ /) is the commercially worthless material that surrounds, or is closely mixed with, a wanted mineral in an ore deposit.It is thus distinct from overburden, which is the waste rock or materials overlying an ore or mineral body that are displaced during mining without being processed, and from tailings, which is rock already stripped of valuable minerals.

Nickel - Extraction and Purification - Mond Process

Iron gives iron pentacarbonyl too, but this reaction is slow. If necessary, it may be separated by distillation. Dicobalt octacarbonyl is also formed in this process, but it decomposes to tetracobalt dodecacarbonyl at the reaction temperature to give a non-volatile solid. Nickel is re-obtained from the nickel carbonyl by one of two processes.

Nickel and Cobalt Production - ScienceDirect

1/1/  · The primary processing of nickel and cobalt is complex, and many routes are taken to produce a salable product. These routes depend upon the original ore and the technology expertise and existing capacity of the producer. Nickel and cobalt often occur together in either oxide (laterite) or sulfide ores. Each type of ore is processed differently.
