Beneficiation of Iron Ore - Mineral Processing & Metallurgy

The mill discharge passes through a wet magnetic separator for further upgrading and also rejection of additional non-magnetic tailing. The ball mill and magnetic cleaner and cyclone all in closed circuit produce an iron enriched magnetic product 85 to 90% minus 325 mesh which is usually the case on finely disseminated taconites.

The Mining Process – Waihi Gold

1. Mining – open pit and underground. To define the ore from the waste rock samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the rock to the primary crushers in the open pit or to the ore stockpiles from underground.

The balls become hard as they cool. The finished product is taconite pellets. Steel The taconite pellets are loaded into ore ships. These ships sail on the Great Lakes to Gary Indiana Cleveland Ohio and other steel-making towns. The taconite pellets are brought to the steel mills to be melted down into steel.

Taconite - Wikipedia

In the late 19th and early 20th centuries the United States was mining such an abundance of iron ore of high quality that taconite was considered an uneconomic waste product. By the end of World War II however much of the high-grade iron ore in the United States had been exhausted. Taconite became valued as a new source of the metal.

Iron | Geoscience Australia

About 98% of world iron ore production is used to make iron in the form of steel. Iron in cast form has many specific uses (e.g. pipes fittings engine blocks) but pure iron is quite soft. Adding a small amount of carbon (usually less than 1%) makes iron into steel which is significantly harder and extremely versatile.

Metal Melt & Pour: Life of a Casting | Reliance Foundry

Smelting is the process of removing a metal element from mined ores. Most metals are found as veins in rocks or as parts of other elements. Smelting is the first step of extraction. Melting is what is done with metal alloys or pure metals. Scrap is melted ore is smelted. Pig iron is the rough iron ingots created from iron ore smelting. Blast ...
