Long Harbour Nickel Processing Plant - Wikipedia

The Long Harbour Nickel Processing Plant is a Canadian nickel concentrate processing facility located in Long Harbour, Newfoundland and Labrador. Operated by Vale Limited, construction on the plant started in April 2009 and operations began in 2014. Construction costs were in excess of CAD $4.25 billion.

Processing of Nickel Ores & Concentrates ‘10 Falmouth ...

the process. The low temperature sulphidation of lateritic ores to produce an intermediate nickel concentrate for further processing offers a potentially lower energy and simpler alternative. The sulphidation of nickeliferous lateritic ores was investigated over a range of temperatures and conditions.

Nickel: smelting, producing-Metalpedia

In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then ...

Copper Nickel Flotation

Cyclic Copper Nickel Flotation Tests. To further clarify the flotation response of the shaft sample, several cyclic tests were carried out. A 6-min grind in the laboratory ball mill was selected for these tests, and the result was a 40-pct minus 325-mesh grind.

EDXRF Analysis of Nickel Concentrate and Filter Cake

While processing nickel, typically sulfidic or lateritic ores are initially crushed and milled to a fine powder. Water is added for creation of a pumpable slurry that is treated with reagents during floatation for concentrating the nickel. The concentrate is further processed by smelting creating ...

Nickel sulphide concentrate processing via low-temperature ...

Nickel sulphate formation is most favourable at 350–450 °C, whereas at higher temperatures, oxide formation is preferred. (2) Nickel sulphate was experimentally proven to be the main nickel containing interaction product of nickel sulphide concentrate and sodium chloride at 400 °C.

Nickel sulphide concentrate processing via low-temperature ...

The low-temperature calcination of nickel sulphide concentrates with NaCl (at 400–450 °C) and subsequent hydrometallurgical processing provide a promising alternative to existing nickel sulphide concentrate processing technologies.

concentrate nickel processing

A nitric acid route for processing a nickel/copper sulphide concentrate This stone is concerned with the processing of an indigenously available pyritic sulphide concentrate for the recovery of the associated nickel and copper value.

OVERVIEW OF PGM PROCESSING - Anglo American Platinum

What of Ni/Cu processing facilities? Similar techno/economic to considerations make typical nickel producers unsuitable Only mixed nickel/copper sulphide capacity is suitable •Ni laterite unsuitable due to copper contamination in the PGM concentrate •Norilsk and Jinchuan have declined our feed in the past

WO2007039663A1 - Processing of nickel sulphide ore or ...

The present invention relates to a new hydrometallurgical process for recovering nickel from nickel bearing raw materials, such as sulphide flotation concentrates. In general, the process involves the oxidative atmospheric pressure leaching of nickel sulphide concentrates using a sodium chloride/hydrochloric acid based leach media.

Concentrate - Boliden

Concentrate; Processed ore becomes concentrates. ... We produce copper, lead, nickel and zinc concentrates. The biggest source of raw materials for our smelters is metal concentrates. We also use certain intermediate forms and secondary materials. We purchase some of the raw materials from mines with which we have agreements.
