Iron Ore Processing,Crushing,Grinding Plant Machine …
Iron ore is the key raw material for steel production enterprises. Generally, iron ore with a grade of less than 50% needs to be processed before smelting and utilization. After crushing, grinding, magnetic separation, flotation, and gravity separation, etc., iron is gradually selected from the natural iron ore.
12.3 Primary Copper Smelting
charge material of copper concentrate mixed with a siliceous flux (often a low-grade copper ore) is heated in air to about 650°C (1200°F), eliminating 20 to 50 percent of the sulfur as sulfur dioxide (SO2). Portions of impurities such as antimony, arsenic, and lead are driven off, and some iron is converted to iron oxide.

Iron ore - Wikipedia
Iron ore being unloaded at docks in Toledo, Ohio. Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), …

(d) The % Weight Recovery is equal to the % Weight of the concentrate in Table 1. It can also be calculated from the assay values given in the table, as follows: % Weight Recovery = 100·(2.09 - 0.1)(20 – 0.1) = 10% (e) The Enrichment Ratio is calculated by dividing the concentrate assay in Table 1 by the feed assay:
