smaller and is decided based on change of ore types, ore / waste contact etc. In case of iron ore, waste bands > 50 cm should be separately sampled. If within the 1m sample there are repetitive bands of waste with thinner intervening ore zones, they may be sampled together, as that the entire sample may analyse as waste or low-grade ore.

What factors influence the amount of iron in well water at different depths? Iron is a common contaminant that can be found in well water. The amount of iron present in well water can vary depending on a variety of factors, including the depth of the well, the type of soil and rock formation surrounding the well, and the presence of other minerals and substances.
