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.

METHOD FOR NICKEL CONCENTRATION

1. A method for nickel concentration processing of a saprolite ore, characterized by comprising the steps of the following (1) to (4). (1) a saprolite ore is subjected to crushing processing to adjust the ore particle size to a size passing a sieve with an mesh opening of 50 mm. (2) a crushed ore obtained in the step of the above (1) is subjected to dry-type grinding processing of the surface ...

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 High Temperature Co-Processing of Nickel

The co-processing of a low-grade nickel concentrate with blended Bulong nickel laterite ore was demonstrated to be effective for the extraction of nickel and cobalt at 250 °C using total pulp densities of 30% w/w and 40% w/w over a range of nickel concentrate to nickel laterite mass

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 ...

ESG and Nickel – Wading Through the Issues

Mining and concentrating where you utilise the run of mine ore and put it through a flotation circuit, in turn upgrading the ore from a low-grade concentrate (say 3 % Ni) to a much higher grade (up to 25% in some cases). This allows the miner to reject the majority of the material mined before complex processing takes place, reducing costs.
