    Iron in plants and soil Plantprobs

    Soil is typically between 1% and 5% iron but because most of this iron is unavailable, it is difficult to set an ideal amount for soil. Some estimates suggest that soil should have at least 0.001 g of iron in every 100 g of soil (or 10 mg/kg). Iron Deficiency. Iron deficiency is most likely to occur in plants when the soil is alkaline or when the level of phosphorus, nitrogen, zinc, manganese or molybdenum in the soil is high.

The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

    Mineral Deposit Value How to Calculate the Potential

    As you can see in the example above, the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately $6 billion worth of minerals). However, in order to be as realistic as possible about this valuation, you can not assume that the complete ore body contains the same grade (i.e. 2% copper and 1.5 gram per tonne gold).
