بيت /laterite nickel ore
The future of nickel lies in laterite ore as opposed to the traditional sulfide ores, according to Hunsaker. Nickel market searches for direction One of the possible ways to reduce pollutants migration in leachate is by enhancing daily soil cover material with laterite soil as amended daily soil cover in landfill.

ore, possibly bypassing the need for expensive mineral acids, and reducing waste disposal problems associated with current processes. 1. INTRODUCTION Worldwide, the majority of nickel is still produced from sulphide sources, although this is rapidly changing, with production from lateritic sources expected to rise to over 50% by 2012.

For a long time nickel was not recognised as a metal in its own right, but was instead regarded as a nonmeltable component of copper ore. This view was not refuted until the 18th century.

Laterite is an important resource for the production of nickel. Prereduction of laterite is a critical step for all laterite based nickel production processes. The main kinds oflaterite, limonitic and serpentinic ore, behave differently upon reduction. Inthis study, general knowledge of laterites and nickel production were introduced. Research on

Customarily, therefore, only enough sulphidizing agent is added to solution derived from leaching reduced lateritic and garnieritic ores to increase the nickel to cobalt ratio in solution to about l000:1 and by so doing the nickel to cobalt ratio in the mixed cobaltnickel sulphide product is .

Nickel Laterite Heap leaching is simple and flexible, and can be applied to the many laterite deposits that currently have no realistic path to production. This paper aims to review the current state of nickel laterite processing and aims to show that heap leaching of nickel laterites is a viable and economically attractive alternative.

Lateritic type nickel deposits are one of the significant sources of nickel and cobalt elements, but generally nickel is dominant [1]. Lateritic ores are widely distributed in the equatorial regions [23]. Oxidic nickel ores are products of weathered ultramafic rocks [4]. Lateritic ores can be classified into three main groups:

copper ores, though there are ample examples gold and copper ores with lower permeability or shear strength (Saavedra, 2014; Ulrich et al., 2003). Nickel laterite ores have very high acid demand, typically in the range of 150 to 500 kg of sulfuric acid per dry tonne of ore, which is about ten times the typical demand for copper.
