    Abstract: A process in which manganese is recovered from manganese nodules after the nodules have been treated to recover base metals such as copper, nickel, cobalt, and molybdenum. The process includes the steps of reacting the manganese in the nodules to yield a carbonate and subjecting the manganese carbonate to flotation. The manganese carbonate froth is collected from the top of a flotation cell, is dried to produce a manganese concentrate, and is sintered to produce a synthetic manganese oxide. Sintering of such concentrates at 1000.degree. C. yields a product containing greater than 50% manganese.The effect of reagent dosage, pH control, and temperature control on the yield of the synthetic manganese oxide is also disclosed.

    Abstract: A process is provided for separation of at least one metal sulfide from a mixed sulfide concentrate. The process may comprise: subjecting the mixed sulfide concentrate to flotation in which at least one sulfide comprising antimony, arsenic and a first metal is floated and at least one sulfide comprising a second metal is depressed. The flotation yields a first metal concentrate having the at least one sulfide comprising antimony, arsenic and the first metal and a second metal concentrate having the at least one sulfide comprising the second metal. The first metal concentrate is leached to yield a further concentrate and a leach solution. The further concentrate comprises the first metal and the leach solution comprises soluble antimony and soluble arsenic. The process may further comprise oxidizing the leach solution to yield an antimony precipitate and an arsenic solution, and forming a stable arsenic compound from the arsenic solution.

    Abstract: A slurry (3) of ground calcite ore in water is subjected to a froth flotation (30) wherein acid insoluble impurities are removed. The flotation process is enhanced by a two-stage pre-flotation conditioning accomplished by adding an acetate salt of a tall oil based imidazoline (5) to the slurry (3) and then mixing a nonpolar hydrocarbon oil (7) into the imidazoline treated slurry. The purified underflow calcium carbonate slurry (11) from the froth flotation is first dewatered to a solids content of 80% to 90% by weight. then reslurried with a dispersing agent (40) and subjected at a solids content of at least 75% by weight to a multi-stage media grinding process (60, 70, 80) wherein each grinding stage is charged with progressively finer grinding media. After degritting, the ground calcium carbonate slurry (17) is ready for shipment as a paper filler-grade product slurry (19) without further dewatering. Alternatively, the product slurry (19) may be passed through an additional fine media grinding stage (100) to-produce a paper coating-grade product slurry (21) also ready for shipment without further dewatering.
