Improvement of Sylvite flotation from halite by starvation feeding the collector octadecylamine
RSC Advances, 2018Co-Authors: Shoujiang Li, Bo Xu, Yunliang Zhao, Peng Chen, Shaoxian SongAbstract:In order to improve the separation of Sylvite and halite in SDIC Xinjiang Lop Nur potash Co. Ltd. (SLNP), in this work, the flotation kinetics of Sylvite and halite under different collector dosages were investigated. It was observed that the increased speed of halite was much faster than Sylvite in terms of flotation rate with an increase in octadecylamine hydrochloride (ODA) dosage. The reason for the upward floating of halite explored by SEM-EDS was that Sylvite was locked with halite, thus it can float up along with Sylvite. According to the analysis results, a strategy of starvation feeding the collector was employed to increase the flotation rate difference between Sylvite and halite, and consequently improve the separation of Sylvite and halite. It has been demonstrated that starvation feeding the collector is an efficient method for obtaining high grade Sylvite, because it can not only improve the separation of Sylvite and halite but also decrease the consumption of ODA in the flotation process.

Improvement of Sylvite flotation from halite by starvation feeding the collector octadecylamine
RSC Advances, 2018Co-Authors: Peng Chen, Yunliang Zhao, Guihua Nie, Shaoxian SongAbstract:The flotation rate of halite increased much faster than that of Sylvite on increasing the ODA dosage. Sylvite locked with halite which allowed the halite to float upward along with the Sylvite. Starvation feeding the collector improved the separation of Sylvite from halite.

Geochimica et Cosmochimica Acta, 1992Co-Authors: Iming Chou, Michael S Sterner, Kenneth S PitzerAbstract:The Sylvite liquidus in the binary system KCl-H2O and the liquidus in the ternary system NaCl-KCl-H2O were determined by using isobaric differential thermal analysis (DTA) cooling scans at pressures up to 2 kbars. Sylvite solubilities along the three-phase curve in the binary system KCl-H2O were obtained by the intersection of Sylvite-liquidus isopleths with the three-phase curve in a P-T plot. These solubility data can be represented by the equation Wt.% KCl (±0.2) = 12.19 + 0.1557T − 5.4071 × 10−5T2, where 400 ≤ T ≤ 770°C. These data are consistent with previous experimental observations. The solidus in the binary system NaCl-KCl was determined by using isobaric DTA heating scans at pressures up to 2 kbars. Using these liquidus and solidus data and other published information, a thermodynamic-PTX analysis of solid-liquid equilibria at high pressures and temperatures for the ternary system has been performed and is presented in an accompanying paper (Part V of this series). However, all experimental liquidus, solidus, and solvus data used in this analysis are summarized in this report (Part IV) and they are compared with the calculated values based on the analysis.
