Hematite(low magnetic) dressing plant   Hematite(week magnetic ore) is refractory minerals. Before, the flotation and roasting-magnetic separating process are mainly used. For the past few years, due to the application of strong magnetic separator, undersize sieve etc new equipment and gravity separation equipment, reverse flotation process, hematite (week magnetic ore) dressing have got remarkable effect

Tin ore separation process   The density of tin ore is bigger than paragenetic mineral , so we use gravity concentration to processing tin ore . Because there are many oxide iron ore inside , for example : magnetite , hematite , if use gravity concentration or flotation , that could not separate them from tin , so magnetic will be added .   Introduction [Application] All kinds of tin minerals ,  teallite,franckeite, cylindrite , canfieldite ,Black boron tin , Malaya Garnet , varlamoffite , schoenfliesite and so on .   [Process Description]   Crushing  and  Screening Crush the raw ore to 20mm, then screen it  to two grade, (20mm~4mm) and (4mm~0mm). Preselecting Put the 20~4mm ore into heavy medium cyclone to be selected. Then the ore will enter into the rod mill. After that, it will be preselected in jig. The tailings over 2mm will be abandoned, the 2mm ore will be put into shaking table. Bulk  Flotation The concentration from jig and shaking board  will be separately selected by bulk flotation. The tailings will enter the  shaking board to get qualified tin concentrates.   Separating  Flotation After the bulk flotation, the concentrate  will be fine grinded, then will be do the flotation separation of lead zinc ore.  After that Lead antimony concentrates and zinc concentrates will be  produced.   Gravity  Separation The pulp enter into Φ300mm hydrocyclone, then overflow to Φ125mm and Φ75mm  hydrocyclone group to  remove the fine mud. The sand setting will enter into the process of thickening, desulphurization by flotation, and then cassiterite flotation .   (Tips: You can add this webpage as favourite, or find it by serach in Google with the keywords below: tin crusher machine, tin mining company, tin mine for sale, tin flotation, tin ore extraction, tin ore mining, tin grinder, tin mining company, tin mining equipment, tin ore mining, tin mining process, tin mining company, tin processing plant, and so on.)
