俄罗斯诺里尔斯克选矿厂选矿新工艺的创立

由于近年来塔尔纳赫斯克选矿厂的生产能力已达到能够处理塔尔纳赫斯克矿山开采的全部富的致密块状硫化矿石。所以，诺尔斯克选矿厂多余的生产能力可以用来分别处理过去同时开采的浸染状矿石和铜矿石，以及处理过去堆存的磁黄铁矿精矿，处理浸染状矿石除采用常规的浮选工艺外还采用闪速浮选和从浮选尾矿中重选回收贵金属；在铜矿石处理中采用正优先浮选流程；在处理堆存的磁黄铁矿精矿时采用贵金属重选预选和给矿磨矿擦洗。

Interaction of Bacillus polymyxa with some oxide minerals with reference to mineral beneficiation and environmental control

Interaction of Bacillus polymyxa with calcite, hematite, corundum and quartz resulted in significant surface chemical changes not only of the cells but also in the minerals. Both the cell surfaces as well as quartz particles were rendered more hydrophobic after mutual interaction, whilst the rest of the minerals exhibited enhanced hydrophilicity after interaction with the bacteria. The bacteria were also observed to be capable of dissolving calcite, hematite and corundum and biosorbing the dissolved metal ions to varying extents. An excess of polysaccharides could be observed on biotreated calcite, hematite and corundum while the predominance of a protein-based metabolic product was evident on quartz surfaces. The utility of bioprocessing in the beneficiation of the above minerals through bioflotation and bioflocculation is demonstrated.

用氮气和戊基黄药浮选时黄铁矿的低电位疏水状态

为了解释和查明N2TEC浮选法的基本原理，本文报道了在用戊基钾黄药(PAX)作捕收剂时，黄铁矿的低电位疏水状态的研究成果。新制定的N2TEC浮选法的目的是提高难处理含金硫化矿金回收率。在典型的N2TEC浮选法中，用氮气代替空气作为浮选气体，戊基钾黄药作为评选含金黄铁矿颗粒的捕收剂。l997年3月，第一个N2TEC浮选工艺在内华达州Lone Tree矿山浮选厂投产，一直操作至今。根据电化学校制接触角测量结果，研究了黄铁矿的低电位、低pH疏水状态与浮选变量(pH、气相组成、捕收剂浓度和黄铁矿电位)之间的关系。
