究了含有独居石、钛铁矿、锆英石、金红石和锡石的潜水层以下海滨砂矿中毛矿精选新工艺，毛矿重选富集后湿式强磁选。磁性产品在自然ｐＨ值条件下，添加水玻璃、ＭＳ－５浮选独居石，浮选精矿经磁选后得品位高于６５％的独居石精矿；独居石浮选尾矿通过磁选得到钛铁矿精矿。非磁性产品用摇床丢尾并将有用矿物分成３组粗精矿和１组中矿，锆英石粗精矿和中矿采用分流流程、捕收剂Ｂ３和抑制剂ＲＷ，在弱酸性条件下浮选，浮选精矿电选除钛后得锆精矿特级品和一级品；锆英石浮选尾矿经电选和金红石粗精矿采用浮选－电选流程均可获得含ＴｉＯ２高于９０％的金红石精矿。锡石粗精矿用电选精选得锡石精矿。
The new technology of wool concentrating in the seashore sand below the aquifer containing monazite, ilmenite, zircon, rutile and cassiterite was studied, and the wet magnetic separation was carried out after re-enrichment of wool ore. Magnetic products at natural pH conditions, adding water glass, MS-5 flotation monazite, flotation concentrate after magnetic separation was higher than 65% purity monazite concentrate; monazite flotation tailings by magnetic separation Get ilmenite concentrate. Non-magnetic products are shaken off the tail and the useful minerals are divided into three groups of crude ore and a group of ore, crude ore and concentrate using zirconium diversion process, collector B3 and inhibitor RW, in weak acid conditions Under the flotation, flotation concentrate electrowinning titanium obtained after the zirconium concentrate special grade and first grade; zirconium flotation tailings by electrowinning and rutile rough concentrate using flotation - electrowinning process can be obtained containing TiO2 is higher than 90% rutile concentrate. Cassiterite concentrate concentrate selection of cassiopeic concentrate.
