The slurry is passed from an outlet of the mixer into a conduit. An additive is introduced into the slurry along a length of the conduit to achieve a flow stream of a slurry/additive mixture. A cross section of the flow stream is expanded in the conduit while not changing direction of the flow stream and a direction of the flow stream is changed while not expanding the cross section of the flow stream and conduit, all prior to the flow steam exiting from an outlet of the conduit.

They also have a first set of pores wherein the pores have an average diameter of less than 100 nm and a second set of pores wherein the pores have an average diameter of at least 100 nm, which second set of pores contains stabilizing organic microgel particles. These inorganic porous particles are prepared using a first oil phase comprising a first water-immiscible aprotic solvent having a dielectric constant of less than 10 and having dissolved therein organic microgel particles. An aqueous phase comprising a polar solvent, an inorganic gel precursor, a catalyst, and a dispersing surfactant is neutralized to initiate condensation of the inorganic gel precursor. An oil-in-water emulsion is then formed with the organic microgel particles in the first oil phase, which is dispersed as first oil phase droplets in the aqueous phase.

    Abstract: Scorodite-type iron-arsenic compound particles in which the particle surface layer part comprise an iron-rich layer having an Fe/As molar ratio of at least 1.24. The particles can be obtained in a reaction process of feeding an oxygen-containing gas to an aqueous solution containing an arsenic(V) ion and an iron(II) ion to precipitate a scorodite-type iron-arsenic compound crystal at a pH of at most 2, in which an oxidizing agent is further added to the liquid before the end of the reaction (treatment A). The particles may also be obtained by a method comprising keeping a scorodite-type iron-arsenic compound particle of good crystallinity in contact with an iron ion-containing aqueous solution having a controlled pH of from 2 to 9 at 0 to 90° C. (treatment B). The scorodite-type iron-arsenic particles have good filterability and excellent arsenic release-preventing effect.
