本文论述的是用浮选法处理含有大比重的浸染型矿物的复杂矿石的研究和实际应用的结果．研究矿样是从科拉半岛科夫多尔矿床采得的含有斜锆石的复杂矿石，斜锆石是一种有价值的稀有矿物，天然ZrO2。密度5．8～6．0g/cm3，品位0．15～0．17％，浸染粒度小于0．2mm．作者对取自重选流程不同地点的含斜锆石的产品进行了全面研究．研究发现，由于比重相近，使一些硫化物（黄铁矿、磁黄铁矿）和烧绿石族矿物（铀烧绿石）也混入了斜锆石精矿中．研究结果表明利用浮选技术有可能进一步提纯斜锆石粗精矿．所采取的重选用矿存在一些显著特点，如搅拌过程中，矿浆固相中较高密度的矿物具有较快的沉降速度，大量的硫化矿物（超过10％）具有较好的可浮性。由于这些特性，考虑使用浮选技术处理含有斜锆石的重选精矿（超过5～10％的ZrO2）．该工艺分三个浮选阶段：第一阶段斜锆石的反浮选，使“轻”矿物（镁橄榄石、磷灰石和碳酸盐）进人泡沫，第二阶段硫化矿物的浮选，第三阶段底流产品中斜锆石的优先浮选．浮选所用药剂：磷酸盐类（三聚磷酸钠、烷基磷酸的单醚和双醚）和黄原酸钠作为硫化矿物的捕收剂．由于捕收剂的选择性和具有较高承载能力的泡沫层的存在，使浮选效率很高．研制了用于从复杂矿石中回收斜锆石的新的?
This article discusses the results of research and practical application of flotation for the treatment of complex ores containing a large proportion of disseminated minerals. The study mineral is a complex ore containing slalite recovered from the Cobdor deposit in the Kola Peninsula, which is a valuable rare mineral, natural ZrO2. Density of 5.8 ~ 6.0g / cm3, grade 0.15 ~ 0.17%, disseminated particle size of less than 0.2mm. The authors conducted a comprehensive study of orthoclase-containing products taken from different locations in the re-election process. The study found that some sulphides (pyrite, pyrrhotite) and pyrochlore minerals (uranium pyrochlore) have also been mixed with orthoclase concentrates due to their similar specific gravity. The results show that the use of flotation technology is likely to further purify the crude ore denticulate. There are some notable features in the re-election of ore. For example, higher density minerals in the solid phase of the slurry have faster settling velocity during the mixing process and a large amount of sulphide minerals (more than 10%) have good floatability. Due to these characteristics, consider the use of flotation technology to treat diagenetic zircon ore concentrate (more than 5 to 10% ZrO2). The process is divided into three flotation stages: the first phase of counter-flotation of slalomite brings “light” minerals (forsterite, apatite and carbonate) into the foam and the flotation of the second stage sulphide mineral , The third stage of the downstream products of oblique zircon preferential flotation. Flotation agents used: phosphate (sodium tripolyphosphate, alkyl phosphoric acid monoether and bis ether) and sodium xanthate as sulphide minerals collector. The flotation efficiency is high due to the selectivity of the collector and the presence of a foam layer with higher load carrying capacity. Developed a new method for the recovery of orthoclase zircon from complex ores?
