Siliceous profiles are defined as having greater than 15% quartz in both siliceous saprolite and siliceous limonite. The limonite zones overlying tire On9a and Puma saprolites are generally thin, discontinuous, and from their chemistry consist of goethite, chromite, several manganese oxide phases, and sporadic amounts of quartz.
The nickel deposit occurs in laterite, a 1030 m thick weathering horizon overlying barren ultramafic bedrock. Two distinct subhorizontal layers make up the laterite: ''limonite'' ore and saprolite ore. Limonite is the reddish, ironrich soil type that forms the uppermost 410 m and represents the most intensely weathered part of the laterite.
Ore processing. The Ravensthorpe ore body is distinctive in that it has a high silica content, which enables the limonite ore to be upgraded to almost twice the mined grade through a beneficiation plant – a simple scrubbing and screening process to remove the barren, hard silica. The saprolite ore also upgrades but to a lesser extent.

We produce two types of nickel ore, namely saprolite ore and limonite ore. We define saprolite ore as nickel ore with iron content of less than 20% and limonite ore as nickel ore with iron content of 20% or higher. Product Mix. We ship out two types of saprolite ore: highgrade and midgrade.
Limonite, or brown ore, is to be found at the bottom of some bogs and shallow lakes, in favorable situations, where the weathering rocks have yielded iron to the water draining into these basins. The limonite accumulates so fast in some places that a lake bottom may be cropped again after a number of years, as at Radnor Forges, Quebec.
