“…In the past decades, tall oil and oxidized petroleum were mainly used as the source of manufacturing anionic collectors for phosphate flotation. Due to the high temperature requirement, low flotation selectivity and relatively huge reagent consumption, alternative sources for fatty acids can be derived from the less expensive vegetable oil, such as rice bran oil, hydrogenated soybean oil, cottonseed oil and jojoba oil [9,41,64].…”

Phosphate ore is an important raw material for manufacturing fertilizers and phosphorous chemical products. While most of the phosphate resources cannot be directly treated as feed stock due to the low grade of P2O5 and high content of impurities. In order to obtain a qualified phosphate concentrate, the beneficiation of the low-grade phosphate ore is, hence, of great necessity. Many beneficiation techniques can be employed to upgrade the P2O5 grade of phosphate ores based on their characteristics in chemical composition and texture. The flotation process is most widely applied to balance the P2O5 recovery ratio and cost. In this review, the dominant techniques for the beneficiation of phosphate ores are introduced. Moreover, the factors that affect the flotation of phosphate ore, including the properties of mineralogy, flotation reagents (depressants and collectors) and flotation medium, were systematically analyzed.

“…Cottonseed oil bought from the local market was chosen as an anionic collector for the flotation experiment after being saponified by sodium hydroxide [16]. Analytical grade calcium chloride, aluminium chloride, magnesium chloride hexahydrate, and ferric chloride hexahydrate were purchased from Sinopharm Chemical Reagent Co., Ltd., Ningbo, China.…”

Abstract:The effects of Ca 2+ , Mg 2+ , Al 3+ , and Fe 3+ on the flotation behaviors of apatite, dolomite and quartz were investigated through a micro-flotation test, and the influence of calcium ions on the flotation of these minerals was further elucidated by solution chemistry study, zeta potential measurement, and X-ray photoelectron spectroscopy (XPS) analyses. The results indicate that an appropriate amount of Ca 2+ and Mg 2+ can improve the floatability of apatite but had a negligible effect on the flotation performance of dolomite, whereas Al 3+ , Fe 3+ , and excessive amounts of Ca 2+ decreased the recovery of apatite and dolomite. The studied metal cations can activate quartz at a particular pH. It can be inferred from solution chemistry and zeta potential measurement that the influence of metal ions on the flotation of different minerals should be attributed to the adsorption of various hydrolysis species on the mineral surfaces. XPS analyses reveal that calcium ions can enhance the adsorption of anionic collector on apatite and quartz surfaces, and there are no apparent changes to be observed on the surface of dolomite in the absence and presence of calcium ions at a concentration of 2.5 × 10 −3 M, which was in good agreement with the micro-flotation results.

“…Sources of fatty acids are usually various vegetable oils: Patau palm oil, 8 cottonseed oil, 9 jojoba oil, 10 and tall oil fatty acids. 11 Vegetable oils are mixtures of unsaturated fatty acids, the main ones of which are oleic, linoleic, and linolenic acids.…”

Interaction Features of Sodium Oleate and Oxyethylated Phosphoric Acid Esters with the Apatite Surface

et al. 2022

Apatite ores are the most important phosphate materials used for the agricultural and livestock chemical production. With the global demand for phosphorous compounds, apatite and other phosphorus-bearing ores are being depleted. The main method of apatite ore enrichment at the moment is the flotation process, the efficiency of which depends on complex heterogeneous processes occurring at the boundary of three phases (“liquid–gas”, “solid–liquid”, and “solid–gas”). Significant influence on the process have the flotation modes and composition of the reagent mixture, which provide a synergistic effect. The purpose of this work was to investigate the reasons for the synergism of surfactants used in apatite ore flotation with fatty acid-based collectors. The object of the study is a monomineral fraction of apatite, separated from the apatite-nepheline ore of Khibiny deposits. In the course of the work, it was found that the mixture of sodium oleate and phospholane PE65 has a synergistic effect on the mineral surface of apatite during foam flotation. The ratio of reagents was determined at which the maximum synergistic effect was observed.
