Abstract: A highly permeable sorbent platform based on polysulfone and polystyrene-b-poly(acrylic acid) composite membranes. The membranes possess a fully interconnected network of poly(acrylic acid)-lined pores, which enables the surface chemistry to be tailored through sequential attachment of polyethyleneimine moieties and metal-binding terpyridine ligands. The polyethyleneimine moieties increase the saturation capacity, while the addition of terpyridine enables high-affinity binding to a diversity of transition metal ions. This membrane platform removes such metal contaminants from solution. The metal capture performance of the functionalized membranes persists even in high concentrations of competitive ions. Also, fluorescence quenching of the terpyridine moiety upon metal ion complexation offers an in-situ probe to monitor the extent of sorbent saturation.

The method comprises providing an aqueous slurry formed by the minerals in finely divided form in water; optionally adding a collector to render the mineral hydrophobic; subjecting the slurry thus obtained to flotation in a flotation cell aerated to form bubbles; and recovering the hydrophobic mineral particles together with the froth to form a concentrate. In the method, an amphiphilic cellulose derivative, is used as such or in combination with a second surfactant as a frother to promote the formation of a stable froth on top of the slurry in the flotation cell. Hydroxypropyl methyl cellulose or hydroxyethyl methyl cellulose are combined with at least one non-ionic organic surfactant or polyglycol esters, for providing a frother. The novel cellulose-based frothers can be used in mineral processing plants to allow for processing of larger quantities of minerals without significant modification of existing facilities.

Abstract: An immersed membranes uses aeration (air bubbles rising past the membranes) as a means to scour the membrane surface and keep it clean from solids, or foulants, allowing for continuous and effective operation. In a module of flat sheet membranes, fine bubble aeration is used to create and maintain space between the membrane sheets. The bubbles inhibit the sheets from touching and clogging together, thus reducing their surface area and their productivity. The aeration may be used for scouring, to supply oxygen to biomass and as a spacer to maintain the working surface area of immersed flat sheet membranes. The face-to-face spacing between the membrane sheets may be 4 mm or less. The bubbles may be less than twice the face-to-face spacing between the membrane sheets.
