摘要： In a method for recovering a copper sulfide concentrate by froth flotation from an ore containing an iron sulfide, hydrogen peroxide is added to the conditioned mineral pulp before or during flotation in an amount effective to lower the redox potential of the conditioned mineral pulp in order to improve concentrate grade and recovery of copper sulfides.

摘要： The invention relates to a process for the selective flotation of kainite from ground potash ores or, for example, from crystallized salt mixtures which are obtained by evaporation processes and can contain other minerals in addition to kainite, such as halite, sylvite and other salt minerals, in order to produce a kainite concentrate fraction and a residue fraction. The separation process is characterized in that the ground or crystallized salt mixture in the form of a crystallizate suspension is intensively mixed with a conditioning-agent combination consisting of a sulfated fatty acid or the alkali salt thereof as the collector reagent and of a known flotation foaming agent (e.g. glycol ethers, monovalent aliphatic alcohols, terpene alcohols, polyglycol ethers etc.) and is subsequently separated into a kainite concentrate fraction and a residue fraction by agitator flotation or pneumatic flotation. The fractions that are formed can be further treated in downstream processes. This process allows an industrial-scale treatment for the selective recovery of kainite from mineral mixtures with the aid of the flotation process.
摘要翻译：本发明涉及从磨碎的钾盐矿石或例如通过蒸发过程获得的结晶盐混合物中选择性浮选红土细菌的方法，并且除了红藻岩之外还可以包含其它矿物，如岩盐，钾盐和其它盐矿物，以生产红松岩精矿部分和残渣部分。分离过程的特征在于将结晶悬浮液形式的研磨或结晶盐混合物与由硫酸化脂肪酸或其碱金属盐作为收集剂和已知的浮选发泡组成的调理剂组合强烈地混合（例如乙二醇醚，一价脂族醇，萜烯醇，聚乙二醇醚等），随后通过搅拌器浮选或气动浮选将其分离成红松岩精矿部分和残余部分。形成的级分可以在下游工艺中进一步处理。这个过程允许工业规模的处理，以便借助浮选过程从矿物混合物中选择性回收红藻岩。

摘要： A new reagent for the application in the preparation of mineral raw materials, mainly sulphide and oxyde mono-and polymetallic ores of non-ferrous metals, which are used as a corrosion inhibitor of the equipment and grinding bodies and as a selective collector of the wanted metal, is described. The new reagent is a composition of water, mercaptobenzothiazole salts and its derivatives in the quantity of 0-50%, by weight, sodium metasilicates in the quantity of 0,1-10%, by weight, amines in the quantity of 1-5%, by weight, and dithiophosphates in the quantitiy of 0,5-20%, by weight. Also, it discloses the methods for the applicationof that new reagent for the preparations of the copper, zinc and lead concentrates from the sulphide and oxyde ores, for the purpose of further metallurgic processing. In those methods the new reagent is added fully, or in part, in the phase of wet grinding, and in part, as needed, in the flotation phase, in the quantity of 20-300g of the reagent per ton of ore. The application of this new reagent eliminates the need for the use of cyanide and other poisonous depressants of metals, as well as other collectors.
