About 0.4 tons. The production of 1 ton pig iron is about 1.6 ton iron ore. If you want to refine 60% of a ton of iron ore, you can't get 600 kilograms of iron. After ironmaking, there will still be a lot of iron in the ore, which cannot be completely extracted. The iron content in the ore is dry basis when it is 60.00% in the test list. Total iron ore ×( 1- moisture content of iron ore )× total iron content of iron ore× output = product quantity.

According to different physical forms, iron ore can be divided into raw ore, lump ore, fine ore, concentrate, sinter and pellet. Lump ore is a high-grade ore that can be directly put into the furnace; Powder ore and concentrate can only be put into blast furnace after artificial briquetting, in which powder ore is the main raw material for sinter production and concentrate is the main raw material for pellet production. Based on the demand of spot market, the target of iron ore futures trading is fine ore.

Extended data

Because the density of iron ore is 4 or 8 tons per cubic meter, the weight of one cubic meter of iron ore is about 4 or 8 tons. Iron ore is an important raw material for iron and steel production enterprises. Natural ore (iron ore) is gradually separated by crushing, grinding, magnetic separation, flotation, gravity separation and other processes. It is a mineral aggregate, which contains iron elements or iron compounds and can be used economically.

Any ore containing economically available iron is called iron ore. There are many kinds of iron ores, among which magnetite (Fe3O4), hematite (Fe2O3) and siderite (FeCO3) are mainly used for ironmaking.
