Iron ore is a nonmetallic ore. Both open-pit mines and underground mines need to apply for safety production licenses before they can be officially put into production. The specific accreditation procedures are basically the same, but there are some minor differences in the materials to be provided. According to China's "Administrative Licensing Law" and other laws and regulations, the safety production license is generally issued within 45 working days after the enterprise submits all the materials. Now government agencies are improving their speed and efficiency, and the time will be shortened a lot.
However, the most important thing is to look at the speed of information provided by mining enterprises. It is most important to sort out all the needed information as soon as possible.
