蛇纹石是一种含水硅酸镁矿物,矿石中常含铁、镍、锰、钴、铬等元素。在我国目前蛇纹石块矿的主要用途是作冶金工业的助熔剂和钙镁磷肥的原料,因而合理利用现在大量废弃的粉矿,对于提高矿山的经济效益、充分利用资源、改善环境条件都具有重要意义。 一、农肥的应用 镁在植物体中有多种功能,在国外被列入植物必须的第四大元素。苏联曾将蛇纹石粉直接施入茶园中,茶树的缺镁症状完全消失,茶叶产量提高20％～25％。捷克的试验表明,在大麦和三叶草田中施入蛇纹石粉其产量均有增加。
Serpentine is a hydrous magnesium silicate mineral, ore often contains iron, nickel, manganese, cobalt, chromium and other elements. In our country, the main purpose of serpentine lump ore is used as raw material of flux and calcium magnesium phosphate fertilizer in metallurgical industry. Therefore, it is necessary to make rational use of the large amount of abandoned fines, which can improve the economic benefits of mines, make full use of resources and improve the environmental conditions It is of great significance. First, the application of agricultural fertilizer Magnesium in plants have a variety of functions in foreign countries have been included in the fourth element of the plant must. Serpentine powder was directly applied to the tea plantation in the Soviet Union. Magnesium deficiency in tea trees completely disappeared, and tea yield increased by 20% to 25%. Tests in the Czech Republic show that the output of serpentine flour is increased in both barley and clover fields.
