WO2010078787A1 A laterite beneficiation process for

A beneficiation process for enriching nickel and/or cobalt involves the steps of dividing nickel laterite into limonite type ore and serpentine type ore to beneficiate separately; classifying by screening at least one time after washing the ore; beneficiating separately the products of the various grades obtained; further classifying by gravity separation and magnetic separation to obtain the

BHP Ravensthorpe Nickel Operation, Australia Mining

Ravensthorpe was a laterite nickel project which, because of the ores’ low grade, and expensive and intensive processing requirements, has caused BHP some headaches. The project was originally approved in March 2004 with a budget of $1,340m. But by November 2006, capital costs rose to $2.2bn.

Major Mines & Projects Ravensthorpe Mine

Beneficiation Nickel and cobalt values are enriched in the fines fractions of both the limonite and Saprolite ores, and the beneficiation process consists of rejecting the principally siliceous coarse fractions using conventional wet ore sizing equipment. Typical mass rejections of 60-70% are achieved at a nominal nickel recovery of 60-65%.

BENEFICIATION OF NICKEL ORES FALCONBRIDGE NICKEL

BACKGROUND OF THE INVENTION This invention relates to the beneficiation of the type of coherent nickeliferous boulder occurring in laterite deposits which has undergone certain weathering processes resulting in a relatively high degree of nickel enrichment at its surface, a relatively minor degree of enrichment at its center, and intermediate degrees of enrichment inwardly from its surface.
