本发明是有关从含钛铁矿矿石中生产金属铁精矿和二氧化钛精矿的方法或是对此类方法的改进。钛工业的一般原料是钛铁矿矿石和钛铁矿精矿,其主要成分是氧化铁和TiO_2。如要求精矿中合钛量高,则氧化铁必须除掉。钛铁矿中的一部分氧化铁可能或多或少地以细小的单独的磁铁矿(Fe_3O_4)结晶存在,而另一部分呈小条带状的Fe_2O_3散布在钛铁矿颗粒中。大量氧化铁通常呈结合状态存在于钛铁矿FeO·TiO_2分子中,这部分铁不能用普通选矿方法除掉。过去已经有许多从钛铁矿中分离铁和二氧
The present invention relates to methods for producing metallic iron concentrates and titania concentrates from ilmenite containing ore, or to improvements of such methods. Titanium industry is the general raw material of ilmenite ore and ilmenite concentrate, the main component is iron oxide and TiO_2. If you require a high content of titanium in the concentrate, the iron oxide must be removed. A part of the iron oxide in the ilmenite may be present more or less in the form of fine single magnetite (Fe_3O_4) crystals, while the other part of the iron oxide particles are dispersed in the ilmenite particles. A large number of iron oxides are usually present in the ilmenite FeO · TiO 2 molecule, which can not be removed by conventional methods. In the past there have been many iron and dioxins isolated from ilmenite
