使用国产石油磺酸钠做捕收剂浮选魏鲁蓝晶石,对比使用氧化石腊皂和胺类捕收剂,浮选该矿蓝晶石,表现出了较强的捕收性和较好的选择性。一、原矿物质组成(一)矿石的矿物组成及结构构造魏鲁蓝晶石矿产于含石榴石蓝晶石黑云母斜长石片麻岩中。有用矿物有:蓝晶石(含量5～10％),铁铝榴石(含量5～10％);脉石矿物有:石英、斜长石、钾长石、黑云母、硅线石;次生矿物有:滑石、绢云母、白云母、水黑云母、次生黑云母;金属矿物有:赤铁矿、褐铁矿;副矿物有:独居石、磷灰石、锆石、金红石、黑电气石、石墨。矿石为柱—粒状、斑状变晶结构,筛状变晶结构,鳞片花岗变晶结构和束状变晶结构。矿石为浸染状构造和片麻状构造。蓝晶石呈半自形柱状、板状,横切面近于四边形,常与黑云母相伴,接触界限较平
The use of domestic sodium petroleum sulfonate collector flotation Weilu kyanite, compared with the use of oxidized wax soap and amine collector, flotation of the mine kyanite, showed a strong harvest and better Selective. First, the composition of the original ore (a) mineral composition and structure of the ore Weilian kyanite mineral containing garnet kyanite biotite plagioclase gneiss. Useful minerals are: kyanite (content of 5 to 10%), almandine (content of 5 to 10%); gangue minerals are: quartz, plagioclase, potassium feldspar, biotite, sillimanite Raw minerals are: talc, sericite, muscovite, water biotite, secondary biotite; metal minerals are: hematite, limonite; deputy minerals are: monazite, apatite, zircon, rutile, black Tourmaline, graphite. The ores are column-granulized, porphyritic, crystal-like, sieve-like, granite-like and bundle-like structures. The ore is disseminated structure and gneiss structure. Kyanite is semi-self columnar, plate-like, cross-section near the quadrilateral, often accompanied by biotite, contact with the flat
