Mine wastes management Mining wastes is generated during the process of extraction, beneficiation and processing of minerals. Extraction is the first phase that consists of the initial removal of ore from the earth. This is normally done by the process of blasting, which results in generation of large volume of waste (soil, debris and other material). This is useless for the industry and is ...

The HIsarna steelmaking process is a process of primary steelmaking in which iron ore is processed almost directly into steel. The process is based on a new type of blast furnace called a Cyclone Converter Furnace, which makes it possible to skip the process of manufacturing pig iron pellets, a necessary step in the basic oxygen steelmaking process. Because it skips this step, the HIsarna ...

Ore:a mineral deposit that has sufficient utility and value to be mined at a profit. Gangue:the valueless mineral particles within an ore deposit that must be discarded. Waste:the material associated with an ore deposit that must be mined to get at the ore and must then be discarded. Gangue is a particular type of waste. A further subdivision of the types of minerals mined by humankind is ...

The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace.

In order to remove the iron oxides and most of the silicon oxides present, the ore is first treated with sodium hydroxide. The digestion process takes advantage of the solubility of amphoteric aluminum oxides to form a solution of aluminate ions, whilst the basic iron oxides which form do not dissolve and are separated by filtration.

The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron. Pores are left behind in the DRI after oxygen has been removed. These pores, if filled with water, for example, can cause the iron to reoxidize with ambient oxygen, generate heat and occasionally ...

Iron Ore. Iron ore is the basic mineral. It forms the backbone of industrial development. There are four varieties of iron ore : Limonite; Haematite (contains 60% to 70% iron) – Most important industrial iron ore. Magnetite (contains 70% iron) — Finest quality, with magnetic properties. Siderite (contains 40% to 50% iron) Manganese Ore. Manganese ore is used for making iron and steel. It ...
