Transcript | netic anomaly will in all probability double the world's supplies, deferring by many centuries the menace of a civilisation bereft of iron. At the present time, first place as regards probable supplies is occupied by the Kerch region, whose supplies are estimated by some geologists at 1 billion tons and by others at 1.5 billion tons. More precise prospecting has been done on the deposits of the Eltigen-Ortel molds and on the mine operated by the Kerch Metallurgical Works. The supplies here were estimated at 169.5 million tons. The Kerch ores represent brown iron-stones containing from 35 to 45 per cent of iron with a large content of phosphor, arsenic, manganese and vanadium. Krivoy-Rog comes first as regards quantity output and quality of ore mined. Its probable stores, accurately prospected, reach 466 million tons running to a depth of 640 metres. Furthermore, at this place up to 40,900 million tons of iron ore quartzites of two types are deposited: rich ore, containing from 40 to 45 per cent of iron, and poor ore, containing from 20 to 25 per cent. According to the opinion of V. G. Mukhin, the entire deposits of these quartzites may yield as high as 7,500 million tons. The Krivoy-Rog ore consists of red iron rocks containing from 50 to 70 per cent of iron. It used to be worked by surface methods; now underground work comprises 48.1 per cent and it grows year by year. The next important iron ore centre is the old Ural ore region. The latter, according to recent data, has about 690 million tons of various iron ores: magnetites, hematites, feldspar and brown iron ores. The actual and probable supplies reach 317.3 million tons, but only 23 per cent are fit for immediate smelting; the remainder needs either simple (37.2 per cent) or even complex dressing (39.8 per cent), i. e., magnetic separation, agglomeration, etc. Consequently, the future progress of the Ural iron ore 56 |
