Definitions
- step a) and/or step c) be carried out at temperatures ranging from 30 to 70 °C.
- step a) and/or step c) be carried out at a temperature of approximately 50°C.
- the following description is in the context of a copper extraction plant.
- the present invention is not confined to separating polonium from this valuable metal and is equally applicable to separating polonium from other valuable metals, such as nickel.
- the prior art in its simplest form is a dust leaching process such as the process shown in Figure 1 and is a single step process carried out on a batch or continuous basis in a leaching tank.
- the process includes forming a slurry of a smelting furnace dust of a copper extraction plant; a raffinate from a solvent extraction circuit of the copper extraction plant or water; and sulphuric acid.
- the density of dust particles in the slurry is of the order of 120 g/L.
- the concentration of sulphuric acid is approximately 100 g/L.
- the pH of the second step is maintained at a value less than the pH of the first step.
- the free sulphuric acid concentration be greater than 50 g/L and more preferably around 100 g/L so as to dissolve polonium and polonium compounds into solution.
