Abstract: Apparatuses and methods are described for the discrimination of particles using sedimentation field-flow fractionation operating without the use of rotating seals. Multiple lines of fluid and electrical communication are provided through a centrifugation unit comprising a fishhook-shaped umbilical conduit traveling from a stationary frame through a rotating guide frame to the separation channel. Twisting and tangling of the umbilical conduit enclosed communication lines are prevented by rotating the guide frame and separation channel in the same direction about an axis at an angular velocity ratio of 1:2. The design eliminates maintenance problems associated with rotating seals, simplifies channel installation and adjustment, and enables the use of multiple channels and the simultaneous application of multiple modes of field-flow fractionation either in concert or in a two-dimensional format.

Abstract: Some mineral processing plants encounter difficulties in dewatering pulps using clarifier/thickener (C/T) equipment due to a layer of fine particles, air bubbles and chemicals formed at the top of the liquid in the thickener. Such layers are very stable and form a cap on the C/T. The dewatering performance of the C/T then deteriorates under these conditions, and a high percentage of solids is contained in the thickener overflow. A process for removing water from rock slurry containing a wide range of particle sizes in mineral processing operations has been developed. The process includes: (a) classifying the feed slurry into two size fractions, namely a coarse fraction and a fine fraction, (b) treating the fine fraction (and the coarse fraction if required) with a selected flocculant, and (3) thickening the flocculated slurry in sedimentation equipment to separate liquid from solids.

Abstract: Wood ash residues are a complex ternary mixture of small stones, biochar particles and ash. The present application shows how a combination of physical separation processes can be applied to the efficient extraction of a biochar-rich fraction. Two different techniques were tested: segregation and elutriation. The effects of the fluidization velocity on both of the processes were investigated respectively. Either technique happened to be ineffective, on its own, to obtain high purity biochar. However, a combination of segregation and elutriation proved to recover 78% of the biochar with a purity of 90%.

Abstract: An inline bitumen froth steam heater system is comprised of steam injection and static mixing devices. The steam heater system heats and de-aerates an input bitumen froth without creating downstream processing problems with the bitumen froth such as emulsification or live steam entrainment. The inline bitumen froth steam heater is a multistage unit that injects and thoroughly mixes the steam with bitumen resulting in an output bitumen material having a homogenous temperature of about 190° F. The heating system conditions a superheated steam supply to obtain saturated steam at about 300° F. The saturated steam is contacted with a bitumen froth flow and mixed in a static mixer stage. The static mixers provide a surface area and rotating action that allows the injected steam to condense and transfer its heat to the bitumen froth. The mixing action and the increase in temperature of the bitumen froth results in reduction in bitumen viscosity and also allows the release of entrapped air from the bitumen froth.

A primary cyclone state, a secondary inclined plate separator stage and a secondary cyclone stage further process the underflow stream to produce a secondary bitumen recovery product stream and a recycle stream. The secondary bitumen recovery product stream is incorporated into and becomes part of the circuit bitumen product output stream. The recycle stream is incorporated into the bitumen froth feed stream for reprocessing by the circuit.

Abstract: A method and system are for sorting shredder residues of metal-containing wastes, in particular of body shells Shredder residues are separated into a shredder light fraction and a non-ferromagnetic fraction (shredder heavy fraction). During the sorting of the shredder light fraction and the shredder heavy fraction in preliminary processes and a main process, a crude-sand fraction is produced by separating out at least a ferromagnetic fraction, a fraction containing nonferrous metals, a fiber fraction, and a granulate fraction. In a refining process, the crude-sand fraction is separated into a residual fraction rich in organics, a dust fraction containing heavy metals, a sand fraction depleted in organics and metals, and a metallic fraction, using the sequential process steps of density separation and metal separation.
