iron oxide copper gold ore deposits. these ore bodies range from around 10 million tonnes of contained ore, to 4,000 million tonnes or more, and have a grade of between 0.2% and 5% copper, with gold contents ranging from 0.1 to >3 grams per tonne parts per million . these ore bodies tend to express as cone-like,

these are crystals of calaverite - a gold, silver and tellurium mineral. this is very high grade gold ore from the cripple creek district in colorado. many old time miners mistook this type of mineral for low grade sulfides, but this silvery metallic material probably is 40 percent gold by weight.

the country is awash with natural resources like gold, diamond and iron ore. liberia is a low-income country dependant on foreign investments for revenue. all the major mines in the country were shut down during the civil war that ended in 2003 and hence the mineral industry's contribution to the country's economy was reduced drastically.
the inferred mineral resources of the putu iron ore project were 1.08 billion mt of iron ore in 2010. iron ore deposits in nimba county are expected to produce 1 million mt of iron ore per year. in 2010, the liberian government estimated the iron ore reserves at mano river to be 80 mt having about 51% iron and that of bomi hills deposits to be 50 mt having nearly 68% iron. the map of liberia. image credits: cia factbook. industrial minerals
mining in mauritania. gypsum production increased by 8.9%; iron ore production, by 6.8%; salt production, by about 35.5%; and crude steel production, by about 4.2%. the sharp increase in copper and gold production was owing to the opening of the guelb mohgrein mine in late 2006.
in the present work, we propose a simple and efficient method for quantitative estimation of minerals in iron ores using elemental assays and thermo-gravimetry analysis data.
the basics. lode deposits of gold containing minerals are the result of volcanic activity, so minerals like quartz may appear near gold. another type of gold ore is the result of cementing within hosts of sedimentary rocks after making its way down a river.
thus :in spathic ores, 5 to 15 per cent, of manganese or carbonaceous matter in a clay stone is an advantage ; whereas some iron ores are decreased in worth by being associated with iron pyrites. magnetic iron ore occurs in granite, gneiss, schist rocks, clay slate, and limestone.
exploitation of existing iron ore deposit is the easier part of the mining operations. the harder part is to find new ore deposits and to define their extent and the iron content grade . exploration is the process by which the accumulations of iron ore minerals can be found in the earths crust.
