The ore dressing production process is to convert the mined iron ore material into the iron ore concentrate. Also, in order to meet the demand of different ore concentrate products from back-end customers in the supply chain, the front-end mining production and mineral processing/dressing production should be coordinated.

The Iron Ore Company of Canada (IOC), which is a joint venture with Rio Tinto as the majority shareholder, produced about 17.7 Mt of iron ore concentrate and pellets at its Carol Lake (see Fig. 1.40) and Labrador City operations, which is railed to Sept-Iles at the mouth of the Saint Lawrence Seaway for shipping to customers (Iron Ore Company ...
