| | The existent states and particle sizes of submicro-gold in pyrity, arsenopyrite | | 利用透射电子显微象、电子衍射和X射线能量色散谱仪研究了黄铁矿、毒砂、石英等矿物中次显微金的赋存状态及其颗粒大小,扩大了寻找金矿床的范围为全矿的综合开采、选矿流程设计及提高金的回收率等方面提供了技术依据。 | | 文摘来源 | | In flotation technological circle, the product' s fraction, grade,metal distribution, pulp density and water quantity were measured and calculated by the metal equilibrium scheme and the pulp equilibrium scheme in the 1950s Since then the design and operation of flotation production have been promoted to a new stage. However, another important factor for flotation process,the distribution and equilibrium of reagents in flotation circle inclnding their measurement and calculation remains to be solved.In thi... | | 50年代选矿领域提出并广泛应用的金属(组分)平衡流程图和矿浆平衡流程图,将选矿工艺流程中的产品重量、品位、金属回收率及分布比例、水量走向及矿浆浓度等重要参数推向定量测算,从而为选矿流程设计、设备规格选择以及生产操作控制提供定量依据,将设计操作水平推向一个新阶段。但多年来,更为重要的浮选药剂在矿浆流程中的走向及浓度分布平衡图的测试计算,尚未形成体系。本文在对矿浆流程中捕收剂(黄药、黑药)分布于水相内和吸附在矿位表面的浓度及比例进行分析测试研究的基础上,计算出浮选药剂分布平衡流程图,并由此讨论药剂制度及浮选流程,作为定量判据,指示改善浮选过程的方向及途径。这里介绍的是以水口山浮选厂为例的测定与计算结果。 | | 文摘来源 | | The whole course of design and construction of the concentrator of Luzhong MMCo. was described. The operational practice for to years since its commissioning in Sept. 1985 has shown the correctness of the pre-construction preparation and dressing process flow design, so that the better operation indices and more economic profits were gained. | | 介绍了鲁中冶金矿山公司选矿厂设计和建设的全过程,以及从1985年9月建成投产至今的10年生产实践,表明该厂的建设前期准备工作及选矿流程设计是正确的,从而使该厂取得了较好的生产技术指标和经济效益。 | | 文摘来源 | |   |
