“…The micro flotation experiments were conducted using an XFG-type flotation machine (Wuhan Exploration Machinery Co., Ltd., Wuhan, China) with a 50 mL flotation cell and an impeller speed of 1800 rpm, Figure 2 presents the schematic of XFG-II flotation machine [11,12]. As for the single mineral flotation, the procedure was described as follows: firstly, 2 g of fluorapatite/dolomite was added in the flotation cell with 50 mL pure water, and then stirred 2 min for dispersion.…”

“…Flotation is a separation and concentrate method that uses the physicochemical features of minerals to separate valuable minerals from gangue minerals [11][12][13], is regarded as the most effective method for removing dolomite from apatite [14]. Traditional fatty acid collectors, particularly oleic acid or its salts, are still the most widely used to separate apatite from dolomite because they are simple to make and inexpensive [3,6].…”

Flotation is the most often employed process to achieve the selective removal of contaminants from the raw materials used in the manufacturing of phosphate fertilizer. However, sodium oleate (NaOL), as a typical collector, is ineffective because of its low collecting ability under low temperature. As a result, developing and implementing feasible alternatives is critical for the long-term output of mines. In this study, sodium dodecyl benzene sulfonate (SDBS), a low-cost and freely soluble reagent under low temperature was used to examine its collecting ability and selectivity in a fluorapatite-dolomite system by means of single and artificially mixed minerals flotation. The adsorption mechanism was evaluated with the help of XPS analyses. The flotation results demonstrate that SDBS could float both fluorapatite and dolomite, but show a higher affinity towards fluorapatite instead of dolomite. Moreover, SDBS could preferred adsorb onto fluorapatite surface when fluorapatite and dolomite coexist. SDBS is more suitable than NaOL for satisfactory recovery of fluorapatite under low temperature in terms of the higher recovery obtained. The XPS analyses results demonstrate that the adsorption of SDBS on fluorapatite surface was more intensively as opposed to that on dolomite surface and Ca active sites on fluorapatite surface are supposed to be the main location for SDBS attachment.

“…They appear in consumer and industrial products from foods, healthcare products, to paints and coatings, as well as being a crucial component of many industrial processes such as oil recovery and printing. Global production of surfactants was reported to be 7 million tonnes annually 20 years ago (1), increasing to 12.5 million tonnes in 2006 (2) and to 14.1 million in 2017 with a forecast growth of 18% by 2022 (35). As of 2019 the market size for surfactants was 39,901million USD globally and is projected to grow to 52,417 million USD by 2025.…”

“…Two decades ago, more than 4.2 million tons (MTs) of detergent products and 1.2 MTs of softener products were used annually in Western Europe (Ivanković & Hrenović, 2010; Pettersson et al, 2000). The annual global surfactant production was reported to be 7 MTs in 2000 (Pettersson et al, 2000), which showed an enormous leap to 12.5 MTs in 2006 (Johnson et al, 2021), and 14.1 MTs in 2017 with an 18% estimated growth by 2022 (Chen et al, 2020; Johnson et al, 2021). Studies have shown that surfactants have contaminated all surface water bodies such as lakes, rivers and the sea.…”

The use of surfactants in households and industries is inevitable and so is their discharge into the environment, especially into the water bodies as effluents. Being surface-active agents, their utilization is mostly seen in soaps, detergents, personal care products, emulsifiers, wetting agents, etc. Anionic surfactants are the most used class. These surfactants are responsible for the foam and froth in the water bodies and cause potential adverse effects to both biotic and abiotic components of the ecosystem. Surfactants are capable of penetrating the cell membrane and thus cause toxicity to living organisms. Accumulation of these compounds has been known to cause significant gill damage and loss of sight in fish. Alteration of physiological and biochemical parameters of water decreases the amount of dissolved oxygen and thus affecting the entire ecosystem. Microbes utilizing surfactants as substrates for energy form the basis of the biodegradation of these compounds. The main organisms for surfactant biodegradation, both in sewage and natural waters, are bacteria.Several Pseudomonas and Bacillus spp. have shown efficient degradation of anionic surfactants namely: sodium dodecyl sulphate (SDS), linear alkylbenzene sulphonate (LAS), sodium dodecylbenzenesulphonate (SDBS). Also, several microbial consortia constituting Alcaligenes spp., Citrobacter spp., etc. have shown efficacy in the degradation of surfactants. The biodegradation efficiency studies of these microbes/ microbial consortia would be of immense help in formulating better solutions for the bioremediation of surfactants and help to reduce their potential environmental hazards.
