Extraction of Tin and Copper by Acid Leaching of PCBs

Tin exists as a dissolved species across a small range of potentials at around 0V, or if the pH is less than -0.42 in the acidic region as shown in the diagram. If pH is greater than 12.6 in very alkaline conditions tin is found to exist as a dissolved species. For the remaining pH range (-0.42 pH 12.6), the tin exists as the solid stannous oxide.

Cassiterite Flotation – Tin Oxide

The nominal size range for cassiterite flotation is between 2 and 100 microns. The top size is variable depending upon the liberation of the cassiterite particles. Cassiterite grains coarser than 100 microns are difficult to float whilst grains finer than 2 microns give selectivity problems. Hence the feed for cassiterite flotation should be reduced to 95% minus 100 microns and then deslimed ...
