蛇纹石是镁的一种含水硅酸盐矿物。一般具有斑点状花纹,特别是其磨光面很像蛇皮,由此得名。 一、工业用途 在化肥工业上,将蛇纹石与磷块岩或磷灰石煅烧制成钙镁磷肥(又称煅烧磷肥)。这种肥料在酸性或中性土壤用作基肥或追肥均可,尤以作基肥更好。每斤钙镁磷肥可增产稻谷2～3斤。每生产一吨钙镁磷肥需消耗蛇纹石(氧化镁含量大于30％)500公斤(高炉法、电炉法、平炉法用量皆同),这方面的蛇纹
Serpentine is a hydrous silicate mineral of magnesium. Generally has a mottled pattern, especially its polished surface is like a snake skin, hence the name. First, the industrial use In the fertilizer industry, the serpentine and phosphorite or apatite calcined calcium magnesium phosphate fertilizer (also known as calcined phosphate fertilizer). This fertilizer in acidic or neutral soil as a base fertilizer or top dressing can be, especially as a base fertilizer better. Per kilogram of calcium magnesium phosphate fertilizer can increase rice 2 to 3 pounds. For every ton of calcium magnesium phosphate produced, it needs to consume 500 kg of serpentine (magnesia content greater than 30%) (blast furnace method, electric furnace method and open heart method), and the serpentine
