How phosphate is mined and processed

2014-4-21  Therefore, spreading phosphate rock on fields had little effect on plant growth. However, in the mid-1800s, chemists discovered that mixing sulfuric acid with phosphate rock would make a soluble fine powder called superphosphate; this discovery turned phosphate rock into the valuable fertilizer it is today. A caveat, however, is that once
