    Abstract: Free-flowing, dense solid particles are prepared via a process comprising providing a solids suspension in a vessel with stirring, directing the suspension to a separation device, which device separates the suspension into a high solids stream and a low solids stream, subjecting the high solids stream to high shear conditions in a high shear compartment and circulating both streams back to the vessel, where the solids suspension is continuously circulated through an integrated apparatus. The integrated apparatus comprises a vessel equipped with a stirring mechanism, a separation device capable of separating a solids suspension into a high solids stream and a low solids stream and a compartment capable of subjecting the high solids stream to high shear conditions, where the separation device is connected to the vessel via a first feed line, the compartment is in-line in a second feed line connecting the separation device and the vessel and the separation device and the vessel are connected via a third feed line, where the first, second and third feed lines are capable of continuously circulating the solids suspension from the vessel to the separation device, circulating the high solids stream from the separation device through the compartment to the vessel and circulating the low solids stream from the separation device to the vessel, respectively and where the apparatus is capable of continuously circulating a solids suspension.

    Abstract: The present invention is directed towards a process for preparing a nickel composite hydroxide with a mean particle diameter in the range from 3 to 20 µm (d50) comprising the step(s) of combining
    (a) an aqueous solution of water-soluble salts of nickel and of at least one of cobalt and manganese, and, optionally, at least one of Al, Mg, B, or transition metals other than nickel, cobalt, and manganese,
    (b) with an aqueous solution of an alkali metal hydroxide and
    (c) with an organic acid or alkali or ammonium salt of an organic acid or an anhydride of an organic acid wherein said organic acid whose nickel(+II) salt has a solubility of 1g/l or less in water at 20°C and, optionally, with
    (d) an aqueous solution of alkali metal aluminate.
