How to distinguish the iron content in iron ore

The easiest way to distinguish is to look at the other party's quality inspection report. If you are not at ease, you can sample yourself for inspection. Pay attention to random sampling and then mix until it is representative. It is better to have CMA qualification for domestic quality inspection reports, so that the credibility of the reports will be higher.

Of course, if the sample size is large and you don't want to spend so much money on testing, you can set up your own laboratory and have a chemist. Send a message if necessary.
