iron and cobalt production equipment process

cobalt processing Uses, Supply, & Facts Britannica

Cobalt contained in and smelted with copper concentrate is oxidized along with iron during the final conversion to blister copper. It then enters the slag layer, which can be treated separately, usually in an electric furnace, and the cobalt recovered by reduction with carbon to a copper-iron-cobalt alloy. In nickel smelting, most of the cobalt is recovered during electrolytic refining of the nickel by precipitation

COBALT PROCESSING DEVELOPMENTS K G Fisher Bateman

The base metal recovery processes giving rise to significant cobalt production can be summarised into four main groups as follows: 3.1 Cobalt Arsenides A variety of processes were in operation during the 20th century to process cobalt arsenide ores/concentrates (refer to

Superalloys containing cobalt are used in the production of jet engines and gas turbine engines for energy generation. These superalloys account for nearly half of the cobalt used each year. Some cobalt is used to make cutting and wear-resistant materials. A synthetic isotope of cobalt, cobalt-60, produces gamma rays. This is used for sterilization of medical supplies and foods, for industrial testing and to

entrained copper and cobalt values from the leach residue that reports to tailings, while the first-stage CCD overflow reports to a low-grade copper SX circuit. The raffinate from this circuit is treated for cobalt recovery. The most common cobalt recovery route involves the sequential precipitation of iron, aluminium and manganese using lime at

Production and Supply Cobalt Institute

Cobalt is widely scattered in the earth’s crust and is found in a variety of different ores in several countries. Cobalt is only extracted alone from the Moroccan and some Canadian arsenide ores. It is normally associated as a by-product of copper or nickel mining operations. Around 55% of the world cobalt production comes from nickel ores.

b) Iron and aluminum by hydrolysis with limestone or lime, and filtering. c) Last traces of copper, plus any zinc or cadmium present, by H2S precipitation and filtering. The resultant solution containing nickel, cobalt, and remaining impurities such as magnesium, manganese and calcium is now ready for the new cobalt separation process.

Fischer–Tropsch process Wikipedia

Recently (since 1990) low-temperature Fischer–Tropsch slurry processes are under investigation for the use of iron and cobalt catalysts, particularly for the production of a hydrocarbon wax, or to be hydrocracked and isomerised to produce diesel fuel, by Exxon and Sasol. Today slurry-phase (bubble column) low-temperature Fischer–Tropsch synthesis is regarded by many authors as the most efficient process for Fischer–Tropsch clean diesel production

4/4/2012· The efficient use of coke and anthracite in producing iron was accelerated by the use of steam-driven equipment, the invention of equipment to preheat air entering the blast furnace and the design of the tuyeres and the tuyere composition (Wakelin, 1999). The evolution of both coke and anthracite ironmaking paralleled each other in the United States during the 1800s, and by 1856 there were 121 anthracite furnaces in operation. With coke

6/9/2019· The parts enriched with nickel, cobalt, and often also iron, are mixed with metallurgical coke. This coke is obtained from bituminous coal in ovens with an oxygen-free atmosphere, removing the volatile content and obtaining a porous coal suitable for these metallurgical treatments. The ore is mixed with calcium oxide and silica, producing a slag. This makes it possible to separate silver, a

4/4/2012· In 1988, Iron Age examined the prospects of iron- and steelmaking, and the article quoted Egil Aukrust, the technical director of LTV Steel, who saw an early end of the era of oxygen steelmaking as a new process in which BOF and EAF get together for an in-bath smelting reduction (McManus, 1988b). And the same article cited the AISI estimate that it would take 10 years before Klöckner-CRA

A cobalt-59 target was introduced into a research reactor where the cobalt-59 atom absorbed one neutron to become cobalt-60. Once the cobalt-60 material was removed from the research reactor it was encapsulated in stainless steel and seal

13/8/2019· According to the Cobalt Development Institute, about 48% of cobalt production originates from nickel ores, 37% from copper ores and 15% from primary cobalt production. The main ores of cobalt are cobaltite, erythrite, glaucodot, and skutterudite. The extraction technique used to produce refined cobalt metal depends on whether the feed material is in the form of (1) copper-cobalt sulfide
