基金项目：2020年度韶关市科技计划项目（编号：200810224537618）收稿日期：2022－09－15基于色选法的钨矿石分选技术冯伯翰，周泽湘，武秀琪（广东松山职业技术学院电气工程学院，广东韶关512126）摘要：针对石英脉型钨矿中石英矿无法被分选利用以及原矿分选效率低的问题，采用色选法研究钨矿石分选技术。介绍韶关地区石英脉型钨矿的矿石性质，指出伴生石英矿与花岗岩废石之间存在的显著分选差异性；对色选机的组成和色选法原理进行分析，利用图像采集系统提取矿石表面颜色；基于RGB颜色空间模型描述矿石颜色，通过计算比较矿石颜色空间距离，精准区分有用矿石与伴生石英矿和花岗岩废石；构造适合原矿分选的色选机，随机选取15～22mm原矿样本进行试验。结果表明：钨矿分选技术能够有效分选含钨矿石、石英矿石和花岗岩废石，可大幅度提高分选效率和分选矿石量，分选量超过2500kg/h，分选精准度超过99%，经济效益和社会效益显著。关键词：色选；钨矿预选；图像采集中图分类号：TD45文献标志码：A文章编号：1009－9492(2023)03－0138－03TungstenOreSortingTechnologyBasedonColorSeparationFengBohan，ZhouZexiang，WuXiuqi（SchoolofElectricalEngineering,GuangdongSongshanPolytechnic,Shaoguan,Guangdong515126,China）Abstract:Inviewoftheproblemsthatquartzoreinquartzveintypetungstenorecannotbesortedandutilizedandtheraworeseparationefficiencyislow,thecolorseparationmethodwasadoptedtostudythetungstenoresortingtechnology.TheorepropertiesofquartzveintypetungstenoreinShaoguanareawereintroduced,andthesignificantcolordifferencesbetweenassociatedquartzoreandgranitewasterockwerepointedout;thecompositionofthecolorsorterandtheprincipleofthecolorseparationmethodwereanalyzed,thecoloroftheoresurfacewasextractedbyusingtheimageacquisitionsystem;thecoloroftheorewasdescribedbasedontheRGBcolorspacemodel;bycalculatingandcomparingthecolorspacedistanceoftheore,theusefulorewasaccuratelydistinguishedfromtheassociatedquartzoreandgranitewasterock;basedonthis,acolorsortersuitableforraworeseparationwasconstructed,and15mm~22mmraworesampleswererandomlyselectedfortest.Theresultsshowthatbyusingthetungstenoresortingtechnology,thetungstenore,quartzoreandgranitewasterockcanbeeffectivelysep...
