The ore is crushed into smaller pieces, usually no larger than six inches in diameter. The crushed ore is then transported to a concentrator or a smelter for further processing. Manganese Ore Grinding: After the manganese ore is crushed, it is then ground into a fine powder in a grinding mill. This process is called milling.
