    Abstract: A method for the manufacture of precipitated calcium carbonate from impure calcium oxide of improved colour is disclosed. The method comprises admixing impure calcium oxide with an aqueous solution consisting essentially of a salt of at least one compound selected from the group consisting of organic amines of the formula RNH2 and alkanolamines of the formula NH2(R1OH), where R and R1 are alkyl groups of 1-4 carbon atoms, and hydrochloric or nitric acid. The solution obtained is treated with a reducing agent e.g. sodium hydrosulphite, separated from insoluble matter and then treated with carbon dioxide or the carbonate of the amine or alkanolamine. Preferably, the amine of the salt and of the carbonate are the same, and the salt is used in at least the stoichiometric amount to dissolve the lime.

    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: Se provee un proceso para la separacion de al menos un sulfuro metalico a partir de un concentrado de sulfuro mezclado. El proceso puede comprender: someter el concentrado de sulfuro mezclado a flotacion donde se somete a flotacion a al menos un sulfuro que comprende antimonio, arsenico y un primer metal y se deprime a al menos un sulfuro que comprende un segundo metal. La flotacion da un primer concentrado de metal con el al menos un sulfuro que comprende antimonio, arsenico y el primer metal y un segundo concentrado de metal con el al menos un sulfuro que comprende el segundo metal. El primer concentrado de metal es lixiviado para dar un concentrado adicional y una solucion lixiviada. El concentrado adicional comprende el primer metal y la solucion lixiviada comprende antimonio soluble y arsenico soluble. El proceso puede tambien comprender oxidar la solucion lixiviada para dar un precipitado de antimonio y una solucion de arsenico, y formar un compuesto de arsenico estable a partir de la solucion de arsenico.
