This project focuses on the geochemical characterization of the iron ore deposits of Ikutha area of Kitui County, which lies in the Mozambique mobile belt. The Ikutha iron ore deposits are situated about 250 Km to the south east of Nairobi. The deposits consist of apatite bearing magnetite veins and mineralized country rock.

The Ikutha iron ore deposits are fairly rich in magnetite and apatite, although other minerals such as amphiboles and pyroxenes are found associated with them. Some of the rocks have high iron values, some as high as over 90%. This iron can therefore be mined economically. Apatite varies between 4%

Application of Magnetic Survey in the Investigation of Iron Ore Deposits and Shear Zone Delineation: Case Study of Mutomo-Ikutha Area, SE Kenya
The main objective of this research was to use ground magnetic survey to delineate shear zone and iron ore deposit within the Neoproterozoic rocks of Mutomo-Ikutha area of south eastern Kenya. Total field magnetic data was recorded by using high resolution proton precision geometric magnetometer which recorded total components of the ground magnetic anomaly data running through sixteen traverses.
Mineralogical characterization of iron ore is a very important and basic aspect that has to get due attention before any attempt for its processing and has become almost inevitable these days because of the increasing demand of the ore. Mineral processing technology is evol-ved to separate and recover ore minerals from gangue in a commercially viable method and is mainly based on the process
As part of a geometallurgical program for the Leveäniemi iron ore mine, the Davis tube was used as proxy to classify ore types, predict iron recoveries in wet low-intensity magnetic separation (WLIMS), and to estimate liberation of mixed particles. The study was conducted by testing 13 iron ore samples with a Davis tube and a laboratory WLIMS.

Chapter 3: Characterisation of airborne dust in a South African opencast iron ore mine: a pilot study, is written in article format.
These techniques have been successfully used in the lithological discrimination of iron ore bearing sheared hornblende gneisses. The capabilities of remote sensing data to characterize the iron ore bearing gneisses, in addition to characterization and mapping the hydrothermal alteration zones helped in identification of iron mineralization regions.

Dec 11, 2013 The exponential demand, improved socio-economic conditions, stringent environmental regulations on mining industry and depletion of massive compact high grade anhydrous iron oxide ores necessitated the processing and utilization of sub and low grade iron ore
The IR spectra of goethite of type 1 iron ore over the 400–4000 cm −1 spectral range is shown in Fig. 3 and Table 1.Generally, goethite of this type can be differentiated from goethite of type 3 by an intense broad band due to the bulk hydroxyl stretch at ca. 3140 cm −1 and two far less intense bands at 3660 and 3484 cm −1 that can be attributed to the surface hydroxyl groups .
Magnetic survey has shown that Iron ore in Mutomo-Ikutha occurs from the surface to 160 meters below the surface in form of veins, dikes, sills, and pod form extending more than 10 kilometers from north- western part of the area towards the south. The iron ore deposit is structurally controlled by shear zone and hosted in. Figure 8
The mineralogical characterisation of tailings of iron ore samples used an integrated mineral analyser known as TIMA-MIRA. The TIMA-MIRA system was designed specifically for the mining industry and enables fast quantitative mineralogical analyzes of rocks, ores, concentrates, tailings, leach residues and foundry products.

AbstractIn order to develop downstream processing routines for iron ore and to understand the behaviour of the ore during processing, extensive mineralogical characterisation is required. Microscopic analysis of polished sections is effective to determine mineral associations, mineral liberation and grain size distribution. There are two main imaging techniques used for the characterisation of
The study aimed at investigating the chemical composition and microstructure of raw iron ore from the deposits in Muko area (south-western Uganda). The quality of this iron ore was evaluated to establish its suitability to serve as a raw material for iron production. Samples were taken from the six hills of Muko ore deposits and tests carried out to establish their composition and properties.
