Abstract The subject of this study is leaching process of nickel bearing laterite ore from Ržanovo, R. Macedonia. The influence of sulfuric acid concentration 0.5, 1 and 3
Arguably the most well known and widely used processing technique for extracting payable metals is smelting The smelting of nickel laterite ore is no different, as the smelting process is the dominant technique and is typically used to make nickel pig iron NPI for the Chinese stainless steel market.
Interest in low grade Ni laterite ores has increased in recent years as high grade Ni sulfide deposits are being quickly depleted. However, processing of Ni laterites has proven technically difficult and costly, and the development of alternative low cost biotechnologies for Ni solubilization has been encouraged.

Although future supplies of nickel depend on laterite ores, their processing is inherently energy intensive and expensive as, unlike sulphide ores, they cannot be significantly upgraded, meaning the entire ore needs to be treated in the process. In addition, hydrometallurgical processes in particular have significant waste disposal problems.
Laterite nickel processing smelting methods and processes are as follows: Laterite Nickel Rotary Kiln The preprocessing step is the raw material of nickel laterite ground with carbon material and flux limestone mixed, and then continuously input laterite nickel ore by rotary kiln.
The specific processes taken depend on whether the ore is a sulfide or a laterite. In the case of sulfides, the reaction of oxygen with iron and sulfur in the ore supplies a portion of the heat required for smelting.

27/08/2012· Laterite Ore Processing Posted on August 27, 2012 by Nanthakumar Victor Emmanuel, P.Eng. Chief Operating Officier, CVMR Corporation Leavement Some of the world class Nickel Laterite ore deposits have Cobalt, Copper and PGE values. Recovering all these metal values in a single refining step is a major challenge.
The segregation process as applied to nickel laterite ores involves the formation of gaseous nickel and iron chlorides which are subsequently reduced to form ferronickel on the surface of a solid carbon reductant. A fundamental study of the process has been carried out

Laterite ores are upgraded before smelting or leaching. The upgrading entails gently crushing and/or grinding the ore and then separating the resulting small, soft, low density Ni rich laterized mineral particles from large, hard, dense, Ni lean, unlaterized precursor rock and by product laterization products, e.g., quartz .
