Obtaining uranium from uraniferous ores containing arsenic

Creators

Description

A uraniferous ore containing arsenic as an impurity is subjected to sulphuric acid attack. The pH of the resulting liquor is adjusted to between 1.5 and 3.5 by the addition of an alkaline agent and iron arsenate precipitates. In order to maximize precipitation of arsenic while minimizing the amount of co-precipitated uranium, the proportion of Fe3+ is increased such that the Fe/As molar ratio is greater than 1
