Atasu iron ore region

ATASU IRON ORE REGION (RU: Атасуйский железорудный район) is situated within the Dzhezkazgan province of the Kazakhstan SSR. It includes more than 20 deposits and ore manifestations (the Western Kara-Jal and the Eastern Kara-Jal, Large Ktay, and others). The centre of the extraction is the Atasu settlement of the mining type. It is known since the 19th century.

The deposits and ore manifestations are of the sedimentary-metamorphosed origin, are situated on the limbs of the Dzhailminskaya syncline among the siliceous-carbonatic rocks of the Lower Carboniferous. They are represented by the slightly and steeply dipping tabular depositions of the magnetite-hematite ores, which are transitioning themselves into the ferromanganese and manganese ores with the thickness from 2 to 50 metres, with the length of several kilometres. The manganese ores form independent depositions within the certain places. The explored reserves of the iron ores are 400 million tonnes (1981). The content of iron within the ores is 40-58%. The deposit of the Western Kara-Jal is being developed by the open pit (since the 1956) and underground (since the 1972) methods. The Large Ktay deposit has been exhausted during the 1962-80 by the open pit method. The mining-technical conditions of the development are favourable. They use the ore without the beneficiation. The extraction is 2.45 million tonnes (1981), there is planned the increase of the extraction up to 10 million tonnes. The Atasu iron ore region is the base of the raw materials for the Karaganda metallurgical plant.
