limestone in nickel processing

nickel processing

Nickel concentrates may be leached with sulfuric acid or ammonia, or they may be dried and smelted in flash and bath processes, as is the case with copper. Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the …


Challenges in Limestone Processing

Therefore, various processing systems are needed to transform raw limestone rock material into a useful product. Common limestone processing methods that prepare the material for subsequent manufacturing stages include drying, calcining, pre-conditioning, and pelletization. The following information highlights limestone processing issues associated with these techniques, as well …

It is generally considered that saprolite ores, which have a high nickel, magnesium and silica content, are best processed by pyrometallurgical processes. Both the pyrometallurgical and hydrometallurgical processes can accept ore from the transition layer between the upper limonite layer and the lower saprolite layer.

Project details CWA was retained to design the offloading and process conveyor systems for Vale-Inco's Long Harbour limestone and nickel concentrate processing facility. The systems are comprised of 15 separate conveyors totalling 1,400 metres in length, including: A 602-metre fully-enclosed tubular offloading conveyor from the wharf to the storage building.


Processing of Nickel Laterite Ores on the Rise

Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry.

Nickel: smelting, producing-Metalpedia

After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copperis removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel concentration greater than 99%. Electrorefining


Limestone Processing – national rocks

Processing involves a series of crushing and screening stages designed to produce material with a specified range of sizes. The primary crusher first roughly crushes material; secondary crushers then reduce the rock size and produce the final size and shape of limestone products after screening. The Flow chart of the processing plant is shown below

One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer. In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro- and carbonyl refined.



limestone uses for nickel processing

In the mining industry, lime products are used to refine and condition metal ores and non-ferrous metals such as Copper, Zinc, Nickel, Gold, Silver and Aluminum. For this application, lime products are used in the froth flotation of Copper, Nickel and Zinc and are used in Gold and Silver processing to ensure proper pH in the leaching circuit.

Nickel Ore

The sources of sulfur in the charge are carbon reductant and heavy fuel oil (1.8% S) and phosphorus, mainly carbon reductant and nickel ore. The smelting of ferronickel using lean nickel ores usually starts with roasting (calcining) of the ore mixture with limestone (~one third of the ore), anthracite (~1/10 of the ore amount), and recycled dust.
