探寻磷矿山

磷矿是指在经济上能被利用的磷酸盐类矿物的总称,是一种重要的化工矿物原料。用它可以制取磷肥,也可以用来制造黄磷、磷酸、磷化物及其他磷酸盐类,以用于医药、食品、火柴、染料、制糖、陶瓷、国防等工业部门。磷矿在工业上的应用已有一百多年的历史。

今天应中化云龙有限公司的邀请,有幸零距离与我们饲料中的重要原料磷酸氢钙的原身接触。也让我对磷又有了深一步的了解。

 我国磷矿资源比较丰富,已探明的资源储量仅次于摩洛哥和美国,居世界第3位。云南、贵州、四川、湖北和湖南5省是我国主要磷矿资源储藏地区,储量达98.6亿t,占全国总储量的74.5%

世界上磷矿石的消费结构中约80%左右生产磷肥后用于农业,其余的用于提取黄磷、磷酸及制造其它磷酸盐系列产品。磷化工产品在工业、国防、尖端科学和人民生活中已被普遍应用。除了在农业中用作磷肥、含磷农药、家禽和牲畜的饲料以外,在洗涤剂、冶金、机械、选矿、钻井、电镀、颜料、涂料、纺织、印染、制革、医药、食品、玻璃、陶瓷、搪瓷、水处理、耐火材料、建筑材料、日用化工、造纸、弹药、阻燃及灭火等方面广泛使用。随着科技的发展,高纯度及特种功能磷化工产品在尖端科学、国防工业等方面被进一步的推广应用,出现了大量新产品,如:电子电气材料、传感元件材料、离子交换剂、催化剂、人工生物材料、太阳能电池材料、光学材料等等。由于磷化工产品不断向更多的产业部门渗透,特别是在尖端科学和新兴产业部门中的应用,使磷化工成为国民经济中的一个重要的产业。磷化工产品在人们的衣、食、住、行各个领域,发挥着越来越重要的作用。
