In order to improve the utilization rate and economic benefits of resources, reduce the backlog of mines and tailings, and pollution to the environment, the Guangzhou Institute of Nonferrous Metals has studied the occurrence of titanium and the comprehensive recovery methods of the difficult minerals in Hainan Island. (Proceedings of the 3rd National Conference on Comprehensive Utilization of Mineral Resources, 1990). The research and experiments show that: 1 Titanium element mainly exists in the titanium-iron ore series formed by the isomorphous substitution of Ti4+ and Fe2+; among them, ilmenite (containing TiO252%～54%) and iron-rich ilmenite The proportion of (including TiO246%) was 66.2%, followed by titanium-rich ilmenite (containing TiO256%~58%) accounting for 19.2%, and titanium hematite (containing TiO210.7%~19.5%) accounting for 14.6%. In addition, titanium is also present in small amounts in rutile, anatase, whitite and vermiculite. ② hard metal selected mineral ilmenite, zircon, monazite, rutile, anatase or the like mixed minerals, mineral grain size 0.2 ~ 0.08mm (genus optional particle size); using diiodomethane media as "ups and downs" beneficiation, gravity < 3.3 The non-useable minerals have a floating removal rate of 19.76 %, and the specific heavy minerals with a specific gravity > 3.3 have a sinking yield of 73.5%. 3 In the heavy minerals that sink, in addition to the main ilmenite, it can comprehensively recover zircon, monazite, titanium-rich ilmenite and rutile; its effective beneficiation process is two: one is the use of useful heavy minerals by electromagnetic selection The field strength 6000Oe sorted out the magnetic product (TiO243%) which accounts for 88.1% of the ilmenite mineral content, and then oxidized and roasted at 800 °C for 10 minutes, and finally the field strength 650 Oe weak magnetic separation, TiO250 can be obtained in the magnetic separation product. ～ ～ 51 % of ilmenite concentrate products; the second is useful heavy minerals (ilmenite concentrate, containing TiO243% ~ 46%) by electro-election (2.1kV, 120r / min), in conductor products Obtained ilmenite concentrate products with 51% to 53% TiO2. 4 In the tailings with a field strength of 8000 - 12000 Oe magnetic separation, flotation can be used to obtain a qualified monazite concentrate; in the non-electromagnetic heavy mineral tailings with a field strength > 20000 Oe magnetic separation With electrification, qualified zircon concentrates can be obtained in non-conducting products, and qualified rutile concentrates can be obtained in conductive products.
The filter disc also called Wire Mesh Filter Disc ,it is made of Stainless Steel Wire Mesh ,sintered wire mesh, sintered felt, perforated metal sheet etc.It can be divided into single layer, multi-layer, round, rectangle, oval and so on.
