对含锡品位0.065～0.085％的残坡积砂矿进行了大型试验,该矿石含泥大,-0.01毫米粒级产出率占64.11％,+0.074粒级产出率占11.86％,锡石结晶粒级细,酸处理后-0.01毫米级锡金属率占28.02％,0.037～0.01毫米占48.52％。铁锡致密结合,原矿含Fe_2O_320.64％,+0.074毫米结合体50.69,0.074～0.01毫米结合体35.6％。针对如此低品位、含泥火、与铁矿
Large-scale experiments were carried out on the residual sands ore containing tin with a grade of 0.065-0.085%. The ore contains large amounts of mud, with a grain yield of -0.01 mm accounting for 64.11% and a grain yield of +0.074 accounting for 11.86% Fine grain size, acid-treated -0.01 mm grade tin metal accounted for 28.02%, 0.037 ~ 0.01 mm accounted for 48.52%. Iron and tin dense combination of raw ore containing Fe2O3 320.64%, + 0.074 mm combination of 50.69,0.074 ~ 0.01 mm combination of 35.6%. For such low grade, clay fire, and iron ore
