This article about chemical and physical properties of Saudi RP is a good read.
AD has said there are no serious contaminants (like cadmium) showing up at in the samples so far.
The article describes effects and threshold levels for other aspects of the RP including
CaO -> increased sulfuric acid requirements
MgO -> problems in flotation and phos acid production
SiO2 -> erosion and corrosion of equipment
R2O3 -> various processing problems
CO2 & organics -> problems with flotation & filtration
Cl -> corrosion in equipment
F -> corrosion and scale and sludge formation
Cd -> heavy metal toxicity in final product
Sr -> inhibits recrystalisation step
rock particle size -> affects acidulation speed and flotation
Have these sorts of details been published for the early drilling of Wonarah RP?
