Because much of the iron-rich ore, the higher the grade, the better the quality of industrial grade set at more than 45%, a phosphorus-containing lower, the lower the cost of sorting and smelting iron ore, smelter is favored, The higher the price. There are two types of mining equipment: 1. Open-pit mining: low cost and high profit, mainly using digging machines, loaders, cars, wind drills , explosives, etc. 2. Underground mining: The cost is high. It also needs tunnel brackets and ventilation equipment, laying mine tracks, and transporting them to the surface by special trains. If you supply ore to the smelter, you can contact the train wagon. If you are providing semi-finished products, you need a set of equipment. The smallest type is also more than 1 million yuan. The ore is ground and sorted (requires a large amount of water). It requires more than 90% iron and is then supplied to the smelter. As for the rational use of resources, mine mining units are generally difficult to do, causing pollution and damage to the environment during mining, and slag is basically useless. If it is a smelter, it will separate other elements in the ore. Come out and use it for other purposes.

Technical requirements for mining of iron ore
In general, there must be mineral deposits of industrial value before they can be considered for mining.
