The manganese present in the form of various manganese carbonate minerals or manganese oxide in the mixed manganese ore accounts for less than 85 of the manganese content in the ore. polymetallic manganese ore is different from the above three kinds of manganese ore, in addition to manganese, it also contains other metal and nonmetal minerals.
All manganese ore consumed in the united states is imported from sources that include gabon, australia, south africa, and brazil. although there are manganese ferroalloy and manganese chemical producers in the united states, the country still imports large amounts of manganese alloys, chemicals, and metal to meet its consumption needs.
The selenium contamination of electrolytic manganese results in a product with a metal purity of 99.7 mn, whereas selenium free manganese has a metal purity of 99.9 mn. the selenium content in manganese metal produced using the selenium technology can be as high as 0.15.
