Solvent extraction and solid phase extraction procedures were also applied to separate Pd from interfering elements before the irradiation in the nuclear reactor. The results obtained by different techniques were compared against each other to examine sensitivity, precision and accuracy.
Important among them are the titanium minerals ilmenite and rutile, as well as zircon and monazite. The largest deposits are worked on the east coast of Australia, where more than 1 million tons of titanium minerals are extracted annually; 1,245,000 tons were mined in 1970, including 877,000 tons of ilmenite.

Cobalt extraction refers to the techniques used to extract cobalt from its Hematite crystallizes in the lattice system, and it has the same crystal structure as ilmenite. Hematite and ilmenite form a solid solution at temperatures above 950 °C. Red ochre contains unhydrated hematite, whereas yellow ochre contains hydrated hematite, the
Selenium is sourced from the pyritic bedrock and concentrations are retained in red weathering smelt soils, but lost in bedrockweathered soils and clays. Selenium correlates with Te, Au, Bi, Cd, Hg, Pb, S, and Sb across bedrock and weathered deposits.

Yellow ochre, FeO·nH 2O, is a hydrated iron hydroxide also called gold ochre Red ochre, Fe 2O3, takes its color from the mineral hematite. Purple ochre, is identical to red ochre chemically but of a different hue caused by different light diffraction properties associated with an average particle size.

The pottery was, however, decorated with designs formed by red ochre and graphite burnishing. In addition, crosshatched designs and fine lines of incisions appeared on some potsherds. These designs are typical of Letaba pottery dated elsewhere to between AD .

Cro magnon man used red ochre in burial sites, place on chest and head, probably associating it with lifegiving blood. Egyptians painted tombs with green, obtained from ground malachite (isolated from mineral by grinding, washing and sifting).

Iron isotope analysis of red and black pigments on pottery
For all experiments, the starting material was the same powdered red ochre from Mina Primavera, which XRD analysis showed is mainly hematite mixed with some barite. This material was placed in a kiln and fired in oxidizing (experiments 1–2) and reducing (experiment 3) atmospheres (Table 5 ).
Cinnabar: A toxic ore of mercury, once used as a pigment
What is Cinnabar? Cinnabar is a toxic mercury sulfide mineral with a chemical composition of HgS. It is the only important ore of mercury. It has a bright red color that has caused people to use it as a pigment and carve it into jewelry and ornaments for thousands of years in many parts of the world.
