The yellowcake is roasted at 800°C, 1472 Deg F, in an oil-fired furnace called a calciner, converting it to 98% pure Uranium oxide
An interdisciplinary physical-chemical approach for characterization of arsenic in a calciner residue dump in Cornwall (UK) [An article from: Environmental Pollution] by J.T. van Elteren
For a given capacity, the volume of the kiln can be reduced by approximately 60 per cent as compared to the suspension pre-heater-kiln system, because the raw meal is decarbonized up to 90 per cent in the pre-calciner.
This allows the differentiation of fuel for calcining the clinker: higher calorific fuel for ensuring high temperatures in the sintering zone of the rotary kiln and less calorific fuel for ensuring decomposition of the carbonate component in the pre-calciner.
Another advantage, which is particularly important from the energy point of view, is that low-grade fuels can be burned in the pre-calciner thus saving high-grade fuels such as fuel oil, gas and high-grade coal.
Therefore, it is possible to feed up to 75 per cent of the fuel into the secondary furnace in kilns with pre-calciners (in practice normally up to 60 per cent is burnt in the pre-calciner).
This is possible because the pre-calciner operates at a temperature of about 900°C which is needed for decarbonation of the raw mix.
It now corresponds, more or less, to the stuff which on the mine is sent to the calciner.
They also reviewed issues related to sales and marketing, safety, operation, calciner and marine, power stations and supply chain.
I would like to remind everybody, we think this is an area of significant unmet medical need although the calciner inhibitors originally advanced the state of the art.
