“…Recent developments suggest that improvements may be achieved with hydrocyclone units in smaller diameter (Yang, et al, 2013), or operated under modified process conditions, e.g., cyclic flow (Zhao, et al, 2008), and application of an electric field (Nenu, et al, 2010), though care must be taken to avoid underflow blockage for small units. Experimental work on utilizing these performance enhancements in hydrocyclone for treating fine mineral tailings slurry has yet been published at this time.…”

Highlights Presented facts on escalating generation of fine mineral tailings worldwide.  Overview of coal, alumina, oil sands, and base metals tailings characteristics.  Reviewed theoretical and industrial developments for tailings management.  Determined numerous knowledge gaps between current theories and practices.  Identified opportunities for improvement towards more sustainable practices. Graphical AbstractEvolution of fine mineral tailings treatment objectives.Figures "Flocculated solids" and "Stackable solids" are adopted from Alamgir, et al. (2012), permission pending. The last figure "Reclaimed land" is adopted from Golder Associates (2009), permission pending. AbstractThe mining industry produces fluid fine mineral tailings on the order of millions of tonnes each year, with billions of tonnes already stored globally. This trend is expected to escalate as demand for mineral products continues to grow with increasingly lower grade ores being more commonly exploited by hydrometallurgy. Ubiquitous presence and enrichment of fine solids such as silt and clays in fluid fine mineral tailings prevent efficient solid-liquid separation and timely re-use of valuable process water. Long-term storage of such fluid waste materials not only incurs a huge operating cost, but also creates substantial environmental liabilities of tailings ponds for mining operators. This review broadly examines current theoretical understandings and prevalent industrial practices on treating fine mineral tailings for greater water recovery and reduced environmental footprint of mining operations.

“…Hydrocyclones have been used in many applications of solid-liquid and liquid-liquid separation (oil and water) (Son et al 2016). Its simplicity of operation, lack of moving parts (other than the pump) and low maintenance costs make it advantageous to use in small-scale operations or low-technology processing, where it can easily be fitted to an existing pump (Bain and Morgan 1983;Hwang et al 2012;Soccol and Botrel 2004;Yang et al 2013). Literature review did not show any commercial applications specific to fresh produce washing/processing.…”

Fruit and vegetable wash-water characterization, treatment feasibility study and decision matrices

On average, it is estimated that up to 5 liters of wastewater is generated per kg of produce in postharvest processing of fruit, leafy greens and root vegetables. The typical wastewater parameters vary in concentration (solids content, COD, BOD, nitrogen, phosphorus) based on the produce being processed. The challenge for producers and regulators is that the selection of the appropriate treatment technology is challenging, so decision matrices were developed to narrow down the treatment selections. Wash-waters for different types of fruit and vegetables from two different operation types, washing only vs. washing and processing. Bench-scale treatments selected for testing included settling, coagulation and flocculation with settling, centrifuge, dissolved air flotation, electrocoagulation, screening, and hydrocyclone. The developed decision matrices summarize the removal effectiveness of the different treatments for typical wastewater parameters and serve as a reference tool in understanding wash-water treatment technologies and their effectiveness in treating various wash-waters.

“…However, its performance is not as great if materials being treated have small particles and low concentration. By contrast, recent studies have reported that mini-hydrocyclone can effectively separate those micro-and submicro-scale fine particles from the carrying fluid medium [7][8][9]. Moreover, the separation precision can be adjusted by changing the geometrical dimension of mini-hydrocyclone or regulating the operation parameters to meet the separation requirements [10].…”
