摘要-I-摘要本次设计以鲁中冶金矿山公司张家洼选矿厂现场资料为参考基础基础，要求设计一个年处理量为230万吨的新建铁矿石选矿厂。严格遵守低能耗、高效率、高回收率的原则进行流程的设计和合适磨选生产设备与辅助设施选择的同时还要达到生产指标；设计中还应尽量降低初期建设资本和建成后的运营成本。此设计的主要内容是选矿厂工艺流程的选择和计算、矿浆流程的计算、设备规格型号和数量的选型和计算、相关图纸（如：主厂房平面图、主厂房剖面图、数质量矿浆流程图等）的绘制。其中，结合选厂现场生产资料确定设计采用一段自磨加一段闭路球磨，设计磨矿细度为-200目75%；设计选别流程有：1、采用一次磁力脱水加两段弱磁选，磁选最终铁精矿品位为64.00%，回收率为79.50%，铁精矿中铜品位为0.0200%；2、采用螺旋溜槽进行重粗选、重扫选和重精选，每段重选有精矿、中矿及尾矿三产物；3、重精选中矿浮扫选及一次浮粗选和一次浮扫选铜，浮选铜精矿品位为22.50%，回收率为45.00%，铜精矿中铁品味为13.50%；4、浮选尾矿采用二次重选提高铁的回收率。结合地形条件设计厂房布置采用平地布置，重选及磁力脱水设计在同一高度平台。设计选矿厂工艺过程能基本实现自流，减少辅助设备的应用降低输送费用。关键词：设计，流程，计算Abstract-II-AbstractThedesignisbasedonLuZhongmetallurgicalandminingcompanybasedonthefielddata，therequirementsfortheannualcapacityof2.3milliontonsofnewconcentrator.Strictlycomplywithlowenergyconsumption，highefficiency，recoveryoftheprinciplesofflowdesignandproductionequipmentchooseappropriategrindingauxiliaryfacilities,whilealsochoosetoproductionindex；Designshouldalsotrytoreducetheinitialconstructioncapitalandaftercompletionoftheoperationcost.Thisdesignismaincontentofconcentratorprocessselectionandcalculationofthepulpofcalculation，specificationmodelandnumberoftypeselectionandcalculation，relevantdrawings(suchas:mainworkshopfloorplan，section，severalqualitypulpflowchart)drawing.AmongcombinedwiththemillthefieldproductionmaterialsuredesignUSESasinceamilladditionclosed-circuitballmill,grindingfinenessfor-200mesh75%;Choosedon'tfloware:1usingamagneticdehydrationandtwoperiodoflowintensitymagneticseparation,magneticseparationultimatelythegradeofironconcentrateis64.00%,andtherecoveryis79.50%,andinthegradeofironconcentratecopper0.0200%;2thespiralchutetoheavyroughing,heavyandchooseandheavychoice,eachsegmentofre-electionhaveconcentrate,separationmiddlingsandtailingsthreeproducts;3heavyselectedseparationmiddlingsandchooseafloatandfloatcyclonesandafloatandcopper,flotationcopperconcentrategradeis22.50%,andtherecoveryrateis45.00%,fecopperconcentratetastefor13.50%;4,theflotationtailingsusingtwore-electionimprovetheironrecovery.Keywords:Keywords:Keywords:Keywords:design,process,calculate目录-III-目录摘要.................................................................................................IAbstract...........................................................................................II目录................................................................................................III第一章概论...............................................................................11.1选矿厂设计重要性.............................................................11.2建厂地区概况......................................................................11.3原矿性质..............................................................................31.4厂区供及电供水..................................................................51.4.1厂区供电.......................................................................................51.4.2厂区供水.......................................................................................7第二章可选性及方案设计论证...........................................82.1矿石可选性研究试验.........................................................82.1.1原矿分析：..................................................................................82.1.2选矿试验结果.............................................................................92.1.3选矿试验报告推荐意见.........................................................92.2方案设计............................................................................102.3方案论证............................................................................11第三章干选手选流程计算......................................................133.1产率计算............................................................................143.2产量计算............................................................................143.3回收率计算........................................................................15第四章磨选工艺流程计算....................................................174.1磨矿流程计算....................................................................174.1.1产量计算....................................................................................184.1.2产率的计算................................................................................184.1.3品位计算....................................................................................19目录-IV-4.1.4回收率计算................................................................................194.1.5矿浆计算....................................................................................204.2选别流程计算....................................................................224.2.1磁力脱水及磁选流程计算..................................................224.2.1.1产率计算................................................................................224.2.1.2产量计算................................................................................234.2.1.3计算未知回收率..................................................................234.2.1.4计算未知品位......................................................................244.2.1.5矿浆计算.........................................................
