Generally, iron ore with a grade of less than 50 needs to go through a dressing process before it can be sent to smelting for utilization. After the mined ore goes through the processes of crushing and grinding, magnetic separation, flotation and gravity separation, the high grade concentrate is obtained.At present, the iron ore resources are decreasing day by day.
Ore deposits are inconsistent in nature, having high concentrations of metals in one area but much lower concentrations in others. Mining geologists perform ore grade control in underground mining operations to figure out where the most profitable ore bodies are, in terms of location and mineral concentration variability. By performing ore grade control, mining operators are also reducing risk.

Mining Mining is the process of taking out the ores from the mines, when an ore occurs near the surface of the earth and can be directly dug out. Such mining is termed as open pit mining. When an ore is taken out form greater depths, then the mining is termed deep mining. Crushing Extracted ore often occurs in big lumps.
Alluvial mining is the cheapest method and, if on a large scale, can be used to mine ores of very low contained value due to low grade, low metal price, or both. For instance, in Malaysia, tin ores （ cassiterite ） containing as little as 0.01 Sn are mined by alluvial methods.
