Manganese ore is usually transported by truck and train from the mine to the buyer (Manganese alloy smelter or trading warehouse), and if exported, it is loaded on ships (usually in bulk, but sometimes in containers). China consumes 65% of the global output of Manganese ore (including 16% produced domestically), so around half of global ...
Ore fines are not readily treatable in SAFs and sintering of ore fines is applied as the main agglomeration technique. Primary manganese ferroalloys, namely HCFeMn and SiMn, are produced in SAFs. Although these are mature technologies, the processes are electrical energy intensive and produce significant amounts of CO 2 gas.
