Magnetic separation is used to separate natural magnetic iron ore (magnetite) from a variety of less-magnetic or non-magnetic materials. It may be conducted in dry or wet environment, with wet systems being commonly used. Magnetic separation operations can also be categorized as either low or high intensity where low intensity separators use magnetic fields between 1,000 and 3,000 gauss and ...

MAGNETIC STUDIES OF IRON ORE MINERAL DEPOSITS IN MBEU

Iron industry in Kenya is dependent on imported raw materials. Local deposits of iron ore have been identified at various places in the country but not much has been done to determine whether the deposits are viable in quantity and quality for commercial exploitation. The location and delineation of the iron deposits and formation in the Mbeu

while rocks on the hills contains medium to high grade iron ore with 40-90% magnetite. The Isiolo-Meru area of Kenya has been a target for mineral exploration since 1940’s [1]. Of particular interest have been the granitic intrusions and relatively young Mbokoro Inlier that were seen to be part of basement rocks whose mineral bearing potential is well documented. However none of the early ...

01/04/2015  The quality of the iron ore was evaluated to establish its suitability as a raw material for iron production in Kenya. Samples were obtained along the perimeter vertices and centre of a land parcel measuring 150m 2 with each excavation being 50cm length, 50 cm width and 500cm depth. Detailed studies were conducted to establish the composition and properties of the 5 samples. X-ray

Magnetite - Wikipedia

Magnetite is a mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally occurring minerals on Earth. Naturally magnetized pieces of magnetite, called lodestone, will attract small pieces of ...

Global Drivers for High Grade Concentrate Magnetite

Iron is extracted from iron ore in a blast furnace by a process known as reduction. The raw materials – iron ore, coke and fluxes – are fed into the top of the furnace. Air, which is heated to about 1200°C, is blown into the furnace through nozzles. The air causes the coke to burn which creates the chemical reaction. The iron ore-based feedstock is reduced to molten iron and slag. Slag is ...
