Silica Iron Ore Mining

Different Types of Iron Ore

Iron formation consists of iron ore such as siderite, magnetite, and hematite, with silica in the form of chert, jasper, etc., generally in bands, but sometimes not distinctly so. The bands of iron ore are at times high-grade, but are often mixed with a good deal of silica, the whole making an ore too lean for use without concentration.

What Are The Advantages And Disadvantages Of High Silica

Jindal Steel and Power High silica low alumina iron ores have no specific disadvantage in blast furnace iron making unless silica is so high that it results in large slag volume Low Al2O3 in ore facilitates and helps in maintaining lower alumina in slag without increasing slag rate and keeps it fluid

Mining Operation Tryex Ore Minerals

The most plausible estimate of magnetite iron ore concentration on this property is around 313 million metric tons or a 104 year supply of 3 million tons of production The costs of production is extremely low because the ore is already in the form of dry loose sand as opposed to the traditional open pit mining that require blasting grinding and sifting
