The Production Of Iron Ore: What Makes Our Main Product

Jan 28, 2016  Ore is a mineral or a collection of minerals (rock) which may be operated economically. Iron ore, for example, Vale’s main product occurs as oxides, carbonates, sulfides and silicates, being the most abundant oxides and greater commercial interest. Our ore, for example, consists mainly of oxides hematite (Fe2O3) and magnetite (Fe3O4).

Mining is a skill about mining ore rocks with the goal of extracting the raw ore from them with a pickaxe. Pickaxes of different tiers mine ores at different speeds. (e.g a Bronze pickaxe is slower then one made of Mithril). A higher mining level allows to mine higher level ores and to mine faster. The mined ores can be made into equipment with smithing or they could be sold to other players ...
