Iron ores are rocks and minerals from which metallic iron can be extracted. There are four main types of iron ore deposit: massive hematite, which is the most commonly mined, magnetite, titanomagnetite, and pisolitic ironstone. These ores vary in colour from dark grey, through to deep purple, rusty red and bright yellow.
Relatively deep deposits, or those with elongated or irregular shapes are typically mined from underground with deep vertical shafts, declines (sloped tunnels) and levels (horizontal tunnels) (Figures 8.2.1 and 8.2.2). In this way it is possible to focus the mining on the orebody itself. In some cases, the near-surface part of an orebody is ...

Solution Mining: Solution mining can substitute for conventional shaft mining in potash deposits that occur below 3,000 feet. Vertical pipes are drilled to supply water to the ore zone and a return pipe brings the saturated brine to the surface where it is evaporated in surface ponds leaving potash. Potassium Uses.
Low Grade Iron Ore Crushing Flow Chart. Iron ore processing plant in China generally use the thick broken, broken and fine broken three sections of crushing flowsheets crushing ore.

The process gases carbon monoxide ( CO C O) and hydrogen ( H2 H 2) are blown into the furnace at temperatures of approx. 1000 °C and flow through the iron ores. The reduction of iron oxides takes place according to the following chemical equations: Fe2O3 Fe2O3 + 3CO + 3H2 → 2Fe → 2Fe + 3CO2 + 3H2O (1) (2) (1) F e 2 O 3 + 3 C O …
Low Grade Iron Ore Grinding Flow Chart. China's iron ore grinding process, most use two stage grinding flowsheet, small and medium-sized concentrator is used more for a grinding process. Due to the fine screening regrinding of new technology, in recent years some concentrator by two section has three segments grinding instead of grinding.
Specifically, the grinding behaviour of two different mill feeds (model quartz and iron ore) together with solid loadings (50, 57, and 67 wt% solids) were correlated against measured acoustic signals.
Coal processing or coal beneficiation uses physical (mechanical) and/or chemical methods to remove rocks, dirt, ash, sulphur and other contaminants and unwanted materials to produce high-quality coal for …
Iron ore is generally sourced from open pits on the planet's surface and typically requires only crushing before it is ready for the smelter. Like most mining, It all starts with a bang. Iron ore and its containing rock are blasted loose with high-explosives, making the ore accessible to machinery and small enough to be transported to the plant.
Understanding the geotechnical properties of iron ore tailings is currently one of the major challenges in the mining industry. With transitions from drained to undrained conditions occurring in ...

What is Strontium. Strontium (Sr) is the 15th most abundant element in the earth's crust. Only two minerals, however—celestite and strontianite—contain strontium in sufficient quantities to make recovery practical, and these minerals are found predominantly in sedimentary rocks. Strontium is a silvery-yellow, metallic element.

Platinum (element #78, symbol Pt) is a dense, silvery-gray metal. The platinum group of elements consists of metals with similar physical properties as platinum and these elements are among the rarest in the Earth's crust. They have high melting points, are dense or heavy and are non-reactive with other elements.
Iron ore is transported from the mine to the steel mill through a supply chain that includes mining, processing, and transportation. The supply chain can be complex, with multiple stakeholders involved in each step of the process. To ensure a reliable supply of iron ore, steel companies often sign long-term contracts with mining companies.
Beneficiation of Iron Ore and the treatment of magnetic iron taconites, stage grinding and wet magnetic separation is standard practice.
