OREAS 196
Артикул: 196
OREAS 196 has been prepared from a blend of classic Ni-Co laterites,
comprising goethite-hosted limonite ores and garnierite/serpentine-rich
saprolite ores sourced from the north-eastern Goldfields of Western Australia
and the north-east of South Sulawesi Province, Indonesia. Mineralisation has
developed through the weathering of ultramafic rocks, including komatiite,
peridotite and dunite. Nickel is concentrated in both the limonite and saprolite
zones. The limonite zone, rich in goethite, hosts most of the cobalt content.
The saprolite zone contains the majority of the nickel, primarily occurring in
silicate minerals such as garnierite, serpentine, and smectite. Secondary
minerals, including chromite, magnetite, hematite, and manganese oxides (e.g.
asbolane or wad), are also present.
Twenty-six commercial analytical laboratories participated in the program to
certify the elements reported below:
Lithium borate fusion whole rock analysis package with X-ray fluorescence
Thermogravimetry: Loss on Ignition (LOI) at 1000 °C
Sodium peroxide/borate fusion with full suite ICP-OES or ICP-MS elemental
packages
Total C and S by infrared combustion furnace
Homogeneity was assessed using XRF analysis on 12 pulp samples (20 g each)
from six sampling units. An ANOVA test was performed to compare within- and
between-unit variances, providing a statistical measure of uniformity and
confirming that all units belong to the same population.
