The ore is then carried out to the primary crusher or process plant. An ore after mining typically contains mostly gangue minerals. The amount of non-valuable gangue minerals could be more than 99.0 % for gold or PGM ores, ~97 % for a copper ore containing 1 % Cu as chalcopyrite.
Mine haul-truck capacity is an important factor at primary crusher installations, because it is cost-effective to integrate truck cycle time at the crusher station with mine/shovel operations. If a primary crusher dump pocket is undersized and unable to handle the mine's trucks, then operators must slowly meter the ore into the receiving hopper.
We will discuss the extraction of iron from iron ore as an example. Extraction of iron. Iron atoms are found in the compounds FeO, Fe 2 O 3 and Fe 3 O 4 and in rocks like haematite and magnetite. South Africa is the seventh largest producer of iron ore in the world. Iron has been mined in South Africa for thousands of years.
Africa is rich in natural resources ranging from arable land, water, oil, natural gas, minerals, forests and wildlife. The continent holds a huge proportion of the world's natural resources, both renewables and non-renewables.

The type of crusher selected will play a role in the shape of the rocks generated from crushing, which may affect sorting. For example, jaw crushers and unloaded cone crushers will produce particles that are flat and elongated while impact crushers and choke-fed cone crushers will make more cubic-shaped particles.
This estimate is in agreement with an energy saving of 11.8% observed in an iron ore application where VSI's were introduced as a crushing step preceding the grinding circuit. View Show abstract

The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.
