Effect of calcium and thiosulfate ions on nickel flotation (KeX 75 g/t). The effect of thiosulfate was negligible in the beginning of flotation, and in some cases nickel recovery was even lower than without thiosulfate addition. This may be a consequence of the lower ion concentrations and more negative pulp potentials after thiosulfate addition.
