Where there is no constraint on concentrate quality, high gold and sulfide flotation recoveries are achievable to the extent that a discardable gold flotation tail is possible (Bax and Bax, 1993; O'Connor and Dunne, 1991 ...
The fatty acid flotation of a difficult-to-float igneous phosphate ore (26.2% P 2 O 5, 15.4% Fe 2 O 3) was investigated through batch flotation tests in the presence of soda ash.The poor flotation of this otherwise high quality ore was attributed to very high concentrations of calcium and sulfate ions (about 1000 and 2000 mg/L, respectively) …
PG, making it difficult to utilize for high-value applications. To address this issue, this study employed a two-stage flotation process to remove the majority of impurities, including SiO 2, organic substances, and fine slime adhered to the surface of PG particles. The raw PG sample was first sieved to remove some SiO 2 particles.
