如何降低泥土中钛和铁的含量，或者说是分解出一部分的钛和铁
有没有可能通过提高温度，使它气态化或者其他方式能够溶解于水中，排掉一部分
有没有大侠能帮我解决啊
谢谢--


For everything there's a season, and a time for every purpose under heaven.
A time to weep, and a time to laugh; a time to mourn, and a time to dance;
A time to cast away stones, adn a time to gather stones togher;
A time to embrace, and a time to refrain from embracing;
