摘要： A process for the separate recovery of phosphate and carbonate minerals from finely-divided phosphate-carbonate-silicate ores or concentrates with a carbonate to phosphate ratio of over 1 is disclosed, in which an anionic collector agent is added to an aqueous slurry of these ores and concentrates, the slurry is then exposed to froth-flotation in order to separate a silicate-bearing residue from phosphate-carbonate concentrate, thereafter(a) the combined phosphate-carbonate concentrate is either treated with a base in order to remove the collector-agent coatings from the surfaces of the mineral particles, whereafter the combined concentrate is froth-flotated with a cationic collector agent using a depressing agent for carbonate in order to recover the phosphate concentrate and the carbonate concentrate separately, or(b) the aqueous slurry to which the anionic collector agent has been added and which has been froth-flotated is treated with sulfur dioxide or carbon dioxide in order to inactivate the collector-agent coatings on the surfaces of the carbonate minerals, whereafter the slurry is froth-flotated in order to obtain separately recovery of a phosphate concentrate and a carbonate concentrate.

摘要： A process is disclosed for the recovery of lead, silver and gold from the iron-bearing residue of an electrolytic zinc process by froth-flotating a slurry of the iron-bearing residue in the presence of a sulfidic collector agent in order to froth-flotate the sulfides and to separate them from the iron-bearing residue. The iron-bearing residue is sulfidized selectively in order to convert the lead, silver and possibly gold substantially quantitatively to sulfides before the iron-bearing residue is froth-flotated.
摘要翻译：公开了一种从电解锌工艺的含铁残渣中回收铅，银和金的方法，该方法是在存在硫化物收集剂的情况下，通过浮选含铁残渣的浆料来浮选浮选液硫化物并将其与含铁残渣分离。含铁残留物被选择性地硫化，以便在含铁残余物被浮选之前将铅，银和可能的金基本上定量转化为硫化物。

摘要： A process for the selective froth-flotation of sulfidic, oxidic and salt-type minerals, whereby an ore is first wet ground to the flotation fineness to obtain a slurry and then the obtained slurry is prepared and froth-flotated. In addition to the collector agent a polysaccharide, lignosulfonate, quargum and/or a surface active additional chemical is used which prevents the collector agent from adhering to the silicate surfaces and passivates active silicate mineral surfaces, or weakens the hydrophobia of minerals to which the collector agent has already adhered. The collector agent and the additional chemical may be added as early as the wet-grinding stage.
