Caliche ore can be found beneath a blanket of inert material between 0.5 and 2.5 meters thick, in layers from 0.2 to 5 meters thick. Caliche ore concentrations vary from one mine to the next. In all, SQM extracts around 30 million tons of caliche ore each year. Caliche ore overburden is removed with bulldozers.

In panning large samples, only one or two specks of gold could be seen, although the ore contained from 1 to 2 ounces per ton. This ore yielded only about 40 per cent, on being amalgamated, but over 90 per cent, was dissolved out by leaching the raw ore with cyanide of potassium, and similar results were obtained by chlorination.

5000 kg ore for each kilogram of uranium recovered. To produce the same amount of uranium, therefore, mill-size can vary by a factor of 10. Most uranium mills use wet grinding, and the resulting slurry is fed to a leaching circuit where sulphuric acid is added. Acid consumption does not depend on the uranium content of the ore, but is ...
