· Altın yaygın olarak, içinde pek çok mineral bulunan kara kum toprak türünün olduğu bölgelerde ve kuvars kayaların arasında bulunur. Altın madeni çoğu zaman büyük kütleler halinde bulunmaz. Toprak arasında ince pullar şeklinde ya da kayaçlar arasında şeritler halinde bulunur. Altın tespit edildikten sonra kazı yapılarak tonlarca toprak çıkarılır.

· Ilmenite is a mantle derived kimberlite indicator mineral (KIM) and has been used as a tracer for kimberlite exploration. Moreover, kimberlites containing magnesian ilmenite are believed to be produced by a reduced magma, thus indicating an environment that preserves diamond, while the presence of Fe 3+-rich ilmenite could indicate an …

· Titanium is the ninth most abundant element in the Earth's crust and it is present mainly in the form of ilmenite (40–80% TiO 2), rutile (~ 95% TiO 2), anatase (> 95% TiO 2), and leucoxene (> 65% TiO 2) [35,36,37,38].Major ilmenite deposits of the world are found in countries such as Australia (eastern and western coast), South Africa (Richards bay), …
· The maximum dissolution of ilmenite was obtained on agitating ilmenite with HCl at a speed of 400 rpm for 300 min resulting in 96.37% and 92.87%, leaching of iron and titanium, respectively. The rate of dissolution could be controlled by two different mechanisms, mainly solid or product layer diffusion and chemical reaction.
Ilmenite is one of the most significant ore s of the metal titanium. It is mined as an important industrial mineral in several deposits throughout the world. Many of those deposits are in heavy placer sands. Ilmenite is very similar in structure to Hematite, and is essentially the same as Hematite with roughly half the iron replaced with titanium.
· Ilmenite is further upgraded to titanium dioxide to be used in paper, plastic, paint colour and cosmetic industries such as sunscreen. According to a 2011 report of ministry of mines, Odisha has third largest deposit of ilmenite in the country. Andhra Pradesh has the biggest deposit followed by Kerala and Tamil Nadu at the second spot.
· Therefore, the use of vanadium-titanium magnetite resources titanium nowadays can only be recycled in the ferromagnetic tail ilmenite . In 1995,the mining ore Ti0 grade is about 11% the metal quantity content is more than 500 000 t, adding the Ti0 ilmenite form, the metal is about more than 40 million tons, its responding ilmenite ore is about 900 000 t.
· Experiments to evaluate the performance of the ilmenite were carried out in a laboratory-scale cylindrical fluidized bed. Losses of the ilmenite were investigated by mixing and recovering the ilmenite using two different coal samples of 13.2–50 mm particle size. Density tracers were used to determine the écart probable moyen (EPM).
· The spatial distribution patterns of Mg-bearing ilmenite (Ilm) composition were studied on 54 kimberlite bodies of the Daldyn field in the Yakutian kimberlite province. The representativity of the ilmenites sampled in this study is ensured by analysing ca. 100 grains from each kimberlite body.
