  • 方法一:硫酸法将钛铁矿粉碎成一定细度的矿粉,再与浓硫酸进行酸解反应。生成块状固相物,用水浸取后,得到钛液(含硫酸氧钛和硫酸亚铁及大量杂质)。通过沉降除去杂质。经冷冻分离除掉硫酸亚铁。添加晶种使硫酸氧钛水解生成偏钛酸(水合二氧化钛),经漂洗、在800~1000℃下煅烧,得到二氧化钛,经粉碎直接作为产品,亦可再继续进行后处理。其 TiO2?FeO+2H2SO4→Ti0SO4+FeSO4+2H2O TiOSO4+2H2O→TiO2?H2O↓+H2SO4 TiO2?H2O→TiO2+H2O 氯化法将金红石或高钛渣原料粉碎成一定粒度与焦炭混合,于900℃在流化床中进行氯化,生成四氯化钛,经净化,加入晶型转化剂,在1300℃左右进行氧化反应,生成二氧化钛,再继续进行后处理,经过滤水洗、干燥、粉碎,得到成品二氧化钛。其 3TiO2+4C+6C12→3TiCl4+2CO+2CO2 TiCl4+O2→TiO2+2C12

  • 防护措施:长期受二氧化钛粉尘作用使人的肺部出现弥漫性肺硬化,支气管炎,以致支气管扩张。 最高容许浓度为10mg/m3。空气中含尘量高时,使用防毒口罩,穿防尘工作服。操作人员定期进行体检。
  • 用途三:用于制作钛白粉、海绵钛、钛合金、人造金红石、四氯化钛、硫酸氧钛、氟钛酸钾、氯化铝钛等。钛白粉可制高级白色油漆、白色橡胶、合成纤维、涂料、电焊条以及人造丝的减光剂、塑料和高级纸张的填料,还用于电讯器材、冶金、印刷、印染、搪瓷等部门。金红石还是提炼钛的主要矿物原料。钛及其合金具有强度高、密度低、耐腐蚀、耐高温、耐低温、无毒等优良性质,并具有能吸收气体、超导等特殊功能,因而广泛应用于航空、化工、轻工、航海、医疗、国防及海洋资源开发等领域。据报道,世界上钛矿物90%以上用于生产二氧化钛白色颜料,而此产品在油漆、橡胶、塑料、造纸等工业中的应用越来越广泛。
  • 属锐钛矿(anatase),旧称八面石,钛矿的主要矿物组分之一,与金红石、板钛矿同属TiO2的同质多象变体,理论含钛60%,四方晶系,晶体呈锥状、板状或柱状等,晶体形态变化大,褐、黄、浅紫、灰黑、浅蓝绿色等,金刚光泽,硬度5.5~6.5,产于区域变质岩系的石英脉中或作为副矿物产于火成岩及变质岩中。
  • 用途二:工艺研究,工业上用于生产钛白粉和海绵钛,也是提炼金属钛的矿物原料。
  • 用途一:用作分析试剂,也用于高纯钛盐的制备及医药工业

  • 方法一:多为露天开采。钛原生矿选矿可分为预选(常用磁选和重选法)、选铁(用磁选法)、选钛(采用重选、磁选、电选及浮选法)三个阶段;钛锆砂矿(主要为海滨砂矿,其次为内陆砂矿)的选矿可分为粗选和精选两个阶段。1995年地矿部郑州综合利用研究所采用磁选一重选一酸浸工艺流程对河南省西峡特大型金红石矿进行选矿,已通过试生产,各项指标均处于国内领先水平。
