  • Publication number: 20240409432
    Abstract: A process for generating a metal sulfate that involves crystallizing a metal sulfate from an aqueous solution to form a crystallized metal sulfate in a mother liquor with uncrystallized metal sulfate remaining in the mother liquor; separating the crystallized metal sulfate from the mother liquor; basifying a portion of the mother liquor to convert the uncrystallized metal sulfate to a basic metal salt; and using the basic metal salt upstream of crystallizing the metal sulfate. So crystallized, the generated metal sulfate may be battery-grade or electroplating-grade.

  • Patent number: 11807865
    Abstract: In accordance with the present invention, a method for increasing the yield of rLV vector particles comprising a trans gene encoding a therapeutic protein or fragment thereof is disclosed. In one approach, cells are transfected with plasmids encoding the necessary components for rLV production using a calcium chloride transfection mix at pH 7.1 wherein the calcium chloride and plasmids form a complex which is added to the cells at a constant speed. The cells are then incubated for a suitable time period wherein virus particle media is collected at least twice during the incubation period and stored in a cold storage unit, thereby reducing virus inactivation.

  • Publication number: 20230046474
    Abstract: A process for removing impurities from a crystallized metal sulfate, including contacting crystallized metal sulfate with a liquor rich in metal sulfate. The metal may be cobalt, nickel, or manganese, and the impurities may be magnesium or calcium. The liquor rich in metal sulfate may be an overflow liquor from crystallization of the metal sulfate, and said overflow liquor may be subject to one or more impurities removal steps prior to contacting the crystallized metal sulfate, such that the overflow liquor contains lower levels of impurities than the crystallized metal sulfate to be contacted. A counter-current wash circuit may be used to remove impurities from a crystallized metal sulfate, whereby a plurality of washing tanks are configured to receive crystallized metal sulfate in a sequence, and washing liquor in reverse of said sequence.
