Two kinds of lateritic nickel ore have to be distinguished: goethite-limonite types and nontronitic clay types. Limonite type laterites (or oxide type) contain 1-2% Ni bound in goethite which is highly enriched due to very strong leaching of magnesium and silica.

The silica content of the Cawse ore is mainly present as iron-rich quartz, whereas in Bulong and Murrin Murrin ore, it is incorporated into clays. In lateritic deposits, the nickel and cobalt do not usually occur in distinct minerals. Along with manganese, they are releasedCurrent world nickel market depends on production from lateritic ores. However, processing of laterite is challenging due to several factors.

    2016-10-7  Processing of lateritic nickel ore through high pressure acid leaching (HPAL) is an established technology proven for extracting nickel from various lateritic ore bodies (Papangelakis et al., 1996; Rubisov et al. 2000; Whittington and Muir, 2000; Whittington and Johnson, 2005; Johnson et al., 2005). However, the atmospheric acidNickel has several metallurgical the world’s nickel production originates from sulphide benefits such as its high melting point of 1453 C, fer- ores while the balance of new nickel is derived from romagnetic properties, catalytic behaviour and ease of lateritic sources. At present, 14 nickel producers are electroplating, Anderson (1996).(PDF) Nickel laterite processing and electrowinning ...Nickel production is a very important activity for the European Union because nickel is a unique constituent of stainless steel. Europe has lateritic (oxidic) ore deposits along a very well-known belt starting from the Alps and ending to the Himalayas.

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 2012.2021-5-16  In the processing of nickel, typically lateritic ores or sulfidic ores are first crushed and milled to a fine powder. Water is added to create a pumpable slurry, which is treated with reagents during the flotation process in order to concentrate the nickel.

Laterite mines are all open cut, due to the large area and shallow nature of the ores, and commonly apply a basic beneficiation to ore before processing (flotation is generally unsuitable). The next major step is high pressure acid leaching
